• Answer:
x = 2
• Step-by-step explanation:
AB = AC/2 = 16/2 = 8
AB = 2x + 4
8 = 2x + 4
2x = 8 - 4
2x = 4
x = 4 : 2
x = 2
PLEASE HELP!!! One step equation... solve by division b/7=5
Answer:
b = 35
Step-by-step explanation:
[tex]\frac{b}{7} =5\\Multiply\: through\: by\: 7\\\\7(\frac{b}{7} ) =5\times 7\\\\b = 35[/tex]
Answer:
multiply both side of the equation by 7.
7 x b/7 = 7 x 5
cancel common factor of 7
b = 7 x 5
b = 35
ax+b=c for x how do I solve this can someone help explain it to me.
Answer:
x= c - b / A
please look at the step by step explanation to better understand :)
Step-by-step explanation:
subtract b from the left side and right side
so you are left with Ax = c - b
divide what number c - b is by A
and you are left with x= c - b / A

A seagull is floating on the surface of the ocean when it takes off and flies upward at a rate of 4 ft per second. After 19 seconds, how far away from the surface of the water will the seagull be?
Answer:
d = 76 m
Step-by-step explanation:
It is given that, the speed of 4 ft per second when it takes off and flies upward
We need to find how far away from the surface of the water will the seagull be after 9 seconds.
Speed is distance over time.
So,
Distance, d = vt
d=4 ft/s × 19 s
d=76 meters
So, the seagull will be at a distance of 76 m from the surface of water.
Mum bought a litre of orange juice. She filled 5 glasses and had 1/5 of a litre left. How much was in each glass?
use this information for items 1-3. Aaron has $65 to rent a bike in the city . It costs $15 per hour to rent a bike. The additional fee for a helmet is $3 for the entire ride
Answer:
You will ride for 4 hrs 8minStep-by-step explanation:
What we are expected to solve for that the problem did not expressly state is most likely the number of hours that you could ride for an amount of $65.
firstly we need to model the inequality (equation) for this scenario.
the constant fee= $3 additional fee for helmet
[tex]3+15n\leq 65\\\\[/tex]
We can now solve for n since the above inequality satisfies the condition presented in the problem statement.
[tex]3+15n\leq 65\\\\15n\leq65-3\\\\ 15n\leq 62[/tex]
Divide both sides by 15 to find n
[tex]n\leq 62/15\\\\n\leq 4hrs -8min[/tex]

Aliyah wants to estimate the value of the quotient of 5.68 x 10- and 8.54 x 10 Which statement about the value is true?
The value will be greater than 1 because (-3)+(-9) is a positive number. A number in scientific notation with a
positive exponent has a value greater than 1.
The value will be greater than 1 because (-3)-(-9) - 6. A number in scientific notation with a positive exponent is
greater than 1.
The value will be less than 1 because 5.88 - 8.54 is less than 1. The negative exponents will make it even smaller.
The number will be less than 1 because 5.68 x 10- is a very small number and division always makes the size of a
number smaller.
Answer:
B-The value will be greater than 1 because (negative 3) minus (negative 9) = 6. A number in scientific notation with a positive exponent is greater than 1.

Answer:
upper bound = 112.5
lower bound = 111.5
Step-by-step explanation:
x = 360 - 59 - 108 - 81
x = 112°
upper bound = 112.5 < 113
lower bound = 111.5 < 112
so
L.B. U.B.
111.5 < 112 < 112.5
Answer:
upper bound = 112.5
lower bound = 111.5
Step-by-step explanation:
x = 360 - 59 - 108 - 81
x = 112°
upper bound = 112.5 < 113
lower bound = 111.5 < 112
so
L.B. U.B.
111.5 < 112 < 112.5

−(−9) = 9
If 5y + 2 = 8/3, what is the value of 5y - 6?
Answer:
5y - 6 = (-16)/3
Step-by-step explanation:
1. Step:
Solve for y:
5 y + 2 = 8/3
Subtract 2 from both sides:
5 y + (2 - 2) = 8/3 - 2
2 - 2 = 0:
5 y = 8/3 - 2
Put 8/3 - 2 over the common denominator 3. 8/3 - 2 = 8/3 + (3 (-2))/3:
5 y = 8/3 - (2×3)/3
3 (-2) = -6:
5 y = 8/3 + (-6)/3
8/3 - 6/3 = (8 - 6)/3:
5 y = (8 - 6)/3
8 - 6 = 2:
5 y = 2/3
Divide both sides by 5:
y = (2/5)/3
3×5 = 15:
Answer: y = 2/15
2. Step.
Evaluate 5 y - 6 where y = 2/15:
5 y - 6 = 5×2/15 - 6
5×2/15 = (5×2)/15:
(5×2)/15 - 6
5/15 = 5/(5×3) = 1/3:
2/3 - 6
Put 2/3 - 6 over the common denominator 3. 2/3 - 6 = 2/3 + (3 (-6))/3:
2/3 - (6×3)/3
3 (-6) = -18:
2/3 + (-18)/3
2/3 - 18/3 = (2 - 18)/3:
(2 - 18)/3
2 - 18 = -(18 - 2):
(-(18 - 2))/3

suppose that Y varies directly with X andY equals 12 when X equals -2 what is X when Y equals -6
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
A direct variation equation has the following format:
[tex]y=kx[/tex]
Where k is a constant.
We know that y is 12 when x is -2. Thus, substitute:
[tex]12=-2k[/tex]
Divide both sides by -2:
[tex]k=-6[/tex]
So, our direct variation equations is:
[tex]y=-6x[/tex]
To find what x is when y equals -6, substitute in -6 for y:
[tex]-6=-6x[/tex]
Divide both sides by -6:
[tex]x=1[/tex]
So, our answer is 1 :)

Simplify the following numerical expression as much as possible: 53*25= ?
Answer:
1325
Step-by-step explanation:
53 * 25 =
Break it apart to solve without a calculator
5 * 25 = 125 and we add a 0 because it's 50 * 25 so 1250
now multiply 3 * 25 = 75
Add them
1250 + 75 = 1325
You can't simplify further.
Answer:
1325
Step-by-step explanation:
53 * 25 = 1325

Mitchell works at the local movie theater. He currently has $395 in his
savings account and he plans to deposit $30 in his account every week.
Define the variable and write an algebraic expression to show how much
money Mitchell will have in his account after any number of weeks.
Answer: 395+30x
Step-by-step explanation:
Given : Mitchell has $395 now.
He saved $30 each week.
Let x be a variable that represents the number of weeks.
Since, Total amount = Current money + (Money save each week ) (Number of weeks)
Then, Total amount = (395 ) + (30)(x)
= 395+30x
Hence, the required algebraic expression= 395+30x
An algebraic expression is a mathematical expression consisting a variable (a,b,c,..) which can be manipulated .

Can u guys PLEASE answer this question ASAP. A fat cat that was initially 12 kg reduces its weight by 10% each month. How long does it take for the cat to be at least 6 kg lighter than its original weight? Give your answer as a whole number of months.
Answer:
It takes at least 7 months for the cat to be at least 6 kg lighter than the original weight.
Step-by-step explanation:
Use exponential decay formula:
A = P (1-r)t
A = amount decreased to
P = original amount
r = rate of decrease
t = time
6 ≥ 12 (1-0.10)t divide both sides by 12
0.5 ≥ (0.9)t take log of both sides
log (0.5) ≥ log (0.9)t power rule of logs lets the exponent t drop to front of log to become a factor
log (0.5) ≥ t log(0.9) divide both sides by log(0.9) which is negative so reverse the inequality sign
log (0.5) / log (0.9) ≤ t use calculator
6.57 ≤ t
It takes at least 7 months for the cat to be at least 6 kg lighter that original weight.
check:
12 (0.9)7≈ 5.73
12 (0.9)6 ≈ 6.37
