parenthesis 3.5*x=3.5x 3.5*2=7
3.5x+7=-4
subtract 7 from both sides
3.5x=-11
divide both sides by 3.5
x=-3.14
or -3 with -.5 remainder
Answer:
x=-22/7
Step-by-step explanation:
multiply 3.5 and x then multiply 3.5 and 2. this will get you 3.5x+7=-4. next you need to subtract the 7 from the -4, resulting in 3.5=-11. finally divide -11 and 3.5, after that you get the answer of x=-22/7 or -3 1/7. if you need decimal form that will be -3.142857

If a triangle has three sides with the lengths 20, 16, and 12, what are the angles?
Answer:
angle a = 53.13°
angle b = 36.87°
angle c = 90°
Step-by-step explanation:
The following is one way to perform the calculation. It may not be the best way.
Calculates ∠A, ∠B, ∠C based on given a, b and c.
∠A = arccos( b2 + c2 - a2 2bc )
= 0.9273 rad = 53.13° = 53.13°
∠B = arccos(a2 + c2 - b2 2ac )
= 0.6435 rad = 36.87° = 36.87°
∠C = arccos(a2 + b2 - c2 2ab )
= 1.5708 rad = π/2 = 90°

Step-by-step explanation:
A. 3x+4/2 = 9.5
3x + 4/2 = 9.5........criss cross
3x+4= 9.5×2
3x = 19-4
3x = 15
x=5 ..........divide both sides by 3
B. 7+ 2x/3= 5.......criss cross
7+2x = 5 × 3
7 + 2x = 15
2x = 15-7
2x = 8......divide both sides by 2
x = 4

Step-by-step explanation:
You spend 264 dollars on clothes. Shirts cost 24 and pants cost :2 you buy a total of 9 items
EQUATIONS:
24x + 32y = 264
x + y = 9
x is shirts, y is pants
SOLVING by substitution:
x = 9 - y
24(9 - y) + 32y = 264
216 - 24y + 32y = 264
8y = 48
y = 6
x + 6 = 9
x = 3

What is the answer for 3/4g = -12
Answer:
Solving the expression: [tex]\frac{3}{4}g=-12[/tex] we get: [tex]\mathbf{g=-16}[/tex]
Step-by-step explanation:
We need to solve the expression: [tex]\frac{3}{4}g=-12[/tex] and find the value of g
Solving:
[tex]\frac{3}{4}g=-12[/tex]
Multiply both sides of the equation by [tex]\frac{4}{3}[/tex] because we need to find value of g.
[tex]\frac{3}{4}g\times \frac{4}{3} =-12\times \frac{4}{3}\\g=-4\times 4\\g=-16[/tex]
So, we get g = -16
Solving the expression: [tex]\frac{3}{4}g=-12[/tex] we get: [tex]\mathbf{g=-16}[/tex]

Solve the equation-7(x-2)= -84
Answer:
x = 14
Step-by-step explanation:
First, use the distributive property:
-7x + 14 = -84
-7x = -98
x = 14
Answer:
my answer got deleted for no reason so ill add it again with my way of solving it with steps this time.
x=14
Step-by-step explanation:
divide both sides by -7
[tex]\frac{-7(x-2)}{-7} =\frac{-84}{-7}[/tex]
simplify
[tex]x-2=12[/tex]
add two to both sides
[tex]x-2=12[/tex]
[tex]+2[/tex] [tex]+2[/tex]
simplify
[tex]x=14[/tex]

A store is selling T-shirts. Which is the best deal?
8 for $26
5 for $30
4 for $15
12 for $39
10 for $45
divide cost by quantity. The lowest rate is the best buy:
26/8 = 3.25 each
30/5 = 6.00 each
15/4 = 3.75 each
39/12 = 3.25 each
45/10 = 4.50 each
The 8 for 26 and the 12 for 39 are both the same price each and are the better buys.
Justin's car used 12 gallons to travel 252 miles. At what rate does the car use gas, in

In a survey of 2,800 people who owned a certain type of car, 1,540 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
55%
Step-by-step explanation:
Calculation for What percent of the people surveyed were satisfied with the car
Percentage of people satisfied=1,540 people/2,800 people
Percentage of people satisfied=0.55*100
Percentage of people satisfied=55%
Therefore the percent of the people surveyed were satisfied with the car is 55%

Answer:
The length is 6.875 (6.9) ft, the width is 5 ft, and the area is 34.375 (34.5) [tex]ft^{2}[/tex]
Step-by-step explanation:
If the scale is 4 in to 5 ft, we can simply divide 5 by 4 to find out the scale by which we would multiply one inch. The reason it is 5/4 and not 4/5 is because 5 ft > 4 in. 5/4 = 1.25. 1.25 * 5.5 = 6.875. When rounded to the nearest tenth, it is 6.9. Using the same measurement NOT rounded, it is 34.375, but using the rounded value the answer is 34.5 sqft.
Hope I helped! Also, if this is wrong someone please correct me.

Colin gets £x wages each week. After he pays his tax of £t, he
then pays his rent of £120. He shares what's left between
himself and his wife. How much do they each get?
Answer:
They will each get ;
(x-t)/2 - 60
Step-by-step explanation:
Here, we want to know the amount of money that Colin and his wife gets
we start by subtracting the necessary terms
Mathematically, that would be;
x-t-120
So what each of them get will be;
(x-t-120)/2
= (x-t)/2 - 60

Answer:

Set up and solve an absolute value inequality to determine the range of possible ... determine if the Democratic candidate will win the election?
Step-by-step explanation:
The percentages candidate could earn falls in the range of absolute value inequality |47 - x| ≤ 4.5.
What is Absolute Value Inequality?Absolute value inequalities are kind of inequality expressions which includes the absolute value symbol in the expression.
For example : |x - 5| < 4 is an absolute value inequality.
Given that,
Percentage of American citizens going to vote for candidate B = 47%
Tolerance level = 4.5%
Suppose x be the percent of voters who will vote for candidate B.
Value of x can be,
47% + 4.5% = 51.5%
Or,
47% - 4.5% = 42.5%
The absolute value inequality for the situation is,
|47 - x| ≤ 4.5
Hence the absolute value inequality is |47 - x| ≤ 4.5.

HELP ME PLEASEEEEEEEEEEEE
Answer:
m<1 = 54
m<3 = 54
m<4 = 126
Step-by-step explanation:
<1: <2 and <1 are supplementary angles.
<3: <2 and <3 are supplementary angles. <1 and <3 are vertical angles.
<4: <2 and <4 are vertical angles.
Supplementary angles equal to 180 degrees.
Vertical angles are equivalent.
Let's solve for <1.
<2 + <1 = 180 --> Due to supplementary angles
126 + <1 = 180 --> Substitution
126 + <1 - 126 = 180 - 126 --> Subtracted 126 on both sides
<1 = 54 --> Simplified
Let's solve for <3.
<3 = <1 --> Due to vertical angles
<3 = 54 --> Substitution
Let's solve for <4.
<4 = <2 --> Due to vertical angles
<4 = 126 --> Substitution
Therefore, m<1 = 54, m<3 = 54, and m<4 = 126
Hope this helped! <3
