Answer:
x=(-3/4)-(5y/4)
Step-by-step explanation:
hello again, the answer is x=(-3/4)-(5y/4). solve using system of equations. please give brainliest
Answer:
Infinitely many solutions
Step-by-step explanation:
=> -16x - 20y = 16 => - 4(4x + 5y) = 12
=> 4x + 5y = 12/(-4) => 4x + 5y = -3 .. (1)
=> 8x + 10y = - 6 => 2(4x + 5y) = - 6
=> 4x + 5y = -6/2 => 4x + 5y = - 3 ...(2)
Note that both the equations come out be same on simplification. It means, we are given with only 1 equation that is 4x + 5y = -3, and since there is nothing more about this, equation would give different values of y for infinitely many random values of x.
Thus,
Equation has infinitely many solutions.

Lisa works at a music store. Last week she sold 6 more than 3 times the number of CDs that she sold this
week. Lisa sold a total of 110 CDs over the two weeks. Find the number of CDs she sold last week and the
number of CDs she sold this week.
Answer:
This week sales = 26
Last week sales = 84
Step-by-step explanation:
Let this week sales = x
Sales last week = 6 + 3x
Sales last week + this week = 110
x + (6 + 3x) = 110
x + 6 + 3x = 110
6 + 4x = 110
4x = 110 - 6
4x = 104
x = 26
This week sales = 26
Last week sales = 6 + 3(26) = 84
Darcie wants to crochet a minimum of 3 blankets to donate to a homeless shelter. Darcie crochets at a rate of 1/15 blanket per day. She has 60 days until when she wants to donate the blankets, but she also wants to skip crocheting some days so she can volunteer in other ways.
Write an inequality to determine the number of days, s, Darcie can skip crocheting and still meet her goal.
Answer:
Since Darcie wants to crochet a minimum of 3 blankets and she crochets at a rate of 1/5 blanket per day, we can determine how many days she will need to crochet a minimum of 3 blankets following the next steps:
- Finding the number of days needed to crochet one (1) blanket:
\begin{gathered}1=\frac{1}{5}Crochet(Day)\\Crochet(Day)=5*1=5\end{gathered}
1=
5
1
Crochet(Day)
Crochet(Day)=5∗1=5
So, she can crochet 1 blanket every 5 days.
- Finding the number of days needed to crochet three (3) blankets:
If she needs 5 days to crochet 1 blanket, to crochet 3 blankets she will need 15 days because:
\begin{gathered}DaysNeeded=\frac{NumberOfBlankets}{Rate}\\\\DaysNeeded=\frac{3}{\frac{1}{5}}=3*5=15\end{gathered}
DaysNeeded=
Rate
NumberOfBlankets
DaysNeeded=
5
1
3
=3∗5=15
- Writing the inequality
If she has 60 days to crochet a minimum of 3 blankets but she can complete it in 15 days, she can skip crocheting 45 days because:
AvailableDays=60-RequiredDaysAvailableDays=60−RequiredDays
AvailableDays=60-15=45DaysAvailableDays=60−15=45Days
So, the inequality will be:
s\leq 45s≤45
The inequality means that she can skip crocheting a maximum of 45 days since she needs 15 days to crochet a minimum of 3 blankets.
Have a nice day!

Why tan(π/4) = 1 can you explain it simply? Also can we use it with cos, cot, sin, sec and cosec? Thanks! please, please dont write random answers it may be reported.
Answer:
1) tan π/4 = 1
2) cos π/4 = 0.7071
3) cot π/4 = 1
4) sin π/4 = 0.7071
5) sec π/4 = 1.4142
6) cosec π/4 = 1.4142
Step-by-step explanation:
Angle π is in radians
But converting to degree, it is;
π = 180˚
Thus; π/4 = 180/4 = 45°
Thus;
1) from calculator; tan π/4 = tan 45° = 1
2) from calculator, cos π/4 = cos 45° = 0.7071
3) cot is equivalent to 1/tan
Thus; cot π/4 = 1/(tan π/4) = 1/tan 45 = 1/1 = 1
4) from calculator, sin π/4 = sin 45° = 0.7071
5) sec in trigonometry is equivalent to 1/cos.
Thus;
sec π/4 = 1/cos π/4 = 1/cos 45° = 1/0.7071 = 1.4142
6) cosec in trigonometry is equivalent to 1/sin
Thus;
cosec π/4 = 1/sin π/4 = 1/sin 45° = 1/0.7071 = 1.4142

Maria who is 6 feet tall stand 20 feet away from the base of a tree she looks up at the top of the tree at 43° angle of elevation what is the approximate height of the tree rounded to the nearest 10th but
Answer:
24.7 feet
Step-by-step explanation:
Maria who is 6 feet tall stands 20 feet away from the base of a tree she looks up at the top of the tree at a 43° angle of elevation.
what is the approximate height of the tree rounded to the nearest 10th?
We solve the above question using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = Angle of elevation
Adjacent = Distance from the base of the tree = 20 feet
Opposite => Height of the tree = x
θ = 43°
tan 43 = x/ 20 feet
x = tan 43 × 20 feet
x = 18.650301723 feet
Approximately = 18.7 feet
We are told in the question that Maria is 6 feet tall
Therefore, the height of the tree = Maria's height + Height
= 6 feet + 18.7 feet
= 24.7 feet

Find the following arc measures
For question 1,3
Answer:
1) arc JL = 127°
arc JML = 233°
3) arc DE = 104°
arc FE = 76°
arc DEF = 180°
arc CFD = 284°
arc DFE = 256°
Step-by-step explanation:
1) arc JL = 127°
arc JML = 360 - 127 = 233°
3) arc DE =104°
arc FE = 180 - 104 = 76°
arc DEF = 180°
arc CFD = 180 + 104 = 284°
arc DFE = 360 - 104 = 256°
The angles arc measures are,
1) arc JL = 127°
arc JML = 233°
3) arc DE = 104°
arc FE = 76°
arc DEF = 180°
arc CFD = 284°
arc DFE = 256°
What is the angle of the circle?An angle of a circle is an angle that is formed between the radii, chords, or tangents of a circle. We saw different types of angles in the Angles section, but in the case of a circle, there, basically, are four types of angles. These are central, inscribed, interior, and exterior angles.
1) arc JL = 127°
arc JML = 360 - 127 = 233°
3) arc DE =104°
arc FE = 180 - 104 = 76°
arc DEF = 180°
arc CFD = 180 + 104 = 284°
arc DFE = 360 - 104 = 256°

What value for x will make the equation true?
−3 ( 7x − 5 ) = 87 + 3x
A. −17/4
B. -3
C. 4
D. 17/3
Answer:
C . 4
Step-by-step explanation:
step 1 : -3 multiply with inside of the ( 7x-5 )
= -21x + 15
step 2 : then it will be 21x + 15 = 87 + 3x
step 3 : switch between the odds into like this
21x - 3x = 87 - 15
step 4 : subtract it all
18x = 72
step 5 : bring 18 to the other side
x = 72/18
step 6 : to find the ans of x is just calculate them
x = 72 ÷ 18
= 4
Or you can do like these ⬇️
-3 ( 7x - 15 ) = 87 + 3x
21x + 15 = 87 + 3x
21x - 3x = 87 - 15
18x = 72
x = 72/18 or 72÷18
x = 4
A company has offices in two different countries. The 125 employees at location A have a mean commute time of 40 minutes and a standard deviation of 15 minutes. The 250 employees at location B have a mean and standard deviation of 35 and 10 minutes, respectively.
Every month, the company takes separate random samples of 20 employees from each location for a survey. Each time, they look at the difference in the mean commute time sampled from each location
Consider the formula: ...
Why is it not appropriate to use this formula for the standard deviation of ...
Choose
A. The samples are not independent of each other.
B. We cannot assume independence for the employees sampled from location A.
C. We cannot assume independence for the employees sampled from location B.
Answer:
B
Step-by-step explanation:
We cannot assume independence for the employees sampled from location A.
It is not appropriate to use this formula for the standard deviation of
A. The samples are not independent of each other.
What is the difference between the sample and the population?The entire group about whom you want to make conclusions is referred to as a population.
The particular group from which you will gather data is known as a sample. The sample size is always smaller than the population as a whole.
We cannot rely on the workers' sampled employees' independence.
Assuming independence based on the 10% condition requires at least 200 employees in the population with a sample size of 20, however, location A only has 125 employees.

A square pyramid has a base length of 4 inches. The height of each triangular face is 12 inches. What is the surface area of the pyramid?
Answer:
The surface area of the given pyramid is 112 [tex]inches^{2}[/tex].
Step-by-step explanation:
Base length of the pyramid = 4 inches
Area of the base = [tex]length^{2}[/tex]
= [tex]4^{2}[/tex]
= 16
Area of its base = 16 [tex]inches^{2}[/tex]
Area of one of its triangular surface = [tex]\frac{1}{2}[/tex] x base x height
= [tex]\frac{1}{2}[/tex] x 4 x 12
= 2 x 12
= 24 [tex]inches^{2}[/tex]
Area of all its four triangular surfaces = 4 x 24
= 96 [tex]inches^{2}[/tex]
surface area of the pyramid = sum of areas of all its surfaces
= 16 + 96
= 112 [tex]inches^{2}[/tex]
The surface area of the given pyramid is 112 [tex]inches^{2}[/tex].
