Answer:
The Correct Answer Is 4
Step-by-step explanation:
So if you have $12 and you can buy $3 with each box of envelopes, you think, how many times can 3 go into 12
count in your head, 3 6 9 12 therefore, ITS 4
here is your equation to match this:
3 x ? = 12
You probably already know this, but i simple way to figure this out is to flip the equation to
12/3 = ?
so from here you can tell that 3 goes into 12 4 times
so the equation is
3 x 4 = 12
Hope It helps!

lines a and b are parallel. if the slope of line a is 1/4 what is the slope of line b?
Answers
if the lines are parallel the slope is the same!
Answer:
1/4
Step-by-step explanation:
we know that the lines A and B are parallel.
The term "parallel" implies that they will never meet each other, and to do so, the lines must have the same slope.
So the slope of line A is the same as line B (as for all parallel lines have the same slope)
So the slope of line B is also 1/4

How can you describe the graph of the equation y= mx + b? Explain
Answers
Answer:
mx is the slope. b is the y-intercept
Step-by-step explanation:
the first thing you should always do is identify your slope this is key for graphing. remember your slope is b so what ever b is you locate that point in the x axis.
then whatever your slope is remember that it is rise over run so say your equation is y=3x+5 you plot the point on the y intercept which is 5. now 3x is your slope so you put it as a fraction to make it easier this is what it looks like in a fraction "3/1" so you go up 3 on the graph and over 1 because of rise/run

The captains of the soccer team describe ordering identical T-shirts for the team. Bindi says the total cost is $192. Gina says the cost is 8t, where t is the number of T-Shirts. Which person tells how much each T-shirt costs? How do you know?
Answers
Answer:
Both of them.
Step-by-step explanation:
Gina says the cost is 8t, which means you can easily find out the cost of each t-shirt if you know the the total cost too. Bindi says the total cost was 192, which is completely useless on its own, but paired with Gina's info, you can get the answer. Divide 192 by 8, and you get the cost of each t-shirt.

A phone company offers two monthly plans. Plan A costs $8 plus an additional $0.09 for each minute of calls. plan B cost $16 plus an additional $0.07 for each minute of calls.
a. For what amount of calling do the two plans cost the same? minutes
b. What is the cost when the two plans cost the same? $
Answers
Answer: 72
Plan A = 30 +0.15x
Plan B = 16 +0.20x
30+0.15x = 16+0.20x
subtract 16 from each side
14 +0.15x = 0.20x
subtract 0.15x from each side
14=0.05x
x = 14/0.05 = 280 minutes
280*0.15 = 42 +30 = $72
280 * 0.20 = 56 +16 = 72
280 minutes and cost $72 each

Step-by-step explanation:
12x+(17x-14)+(2x+5)+90 = 360
31x+81 = 360
31x = 279
x = 9
arc AD = 12(9) = 108 degrees

HELP ASAP 3.) Andy's Karpet Kleaning charges a $23 consultation fee, plus $17 per hour to clean carpets. Stanley
Steemer charges a $37 consultation fee, plus $13 per hour. After how many hours will the total charge be the
same? What is the charge?
Answers
Answer:
After 3.5 hours and the charge is $82.50.
Step-by-step explanation:
Setting up the equations equal to each other will give a solution (x-value) that makes both sides equal (the same price) after the same amount of hours (x-value).
13x + 37 = 17x +23
x = 3.5
Then plug the hours into either side to get the equal price.
13(3.5) + 37 = $82.50
OR
17(3.5) + 23 = $82.50
The value of a car decreases by 5% each year. Sophie bought a car two years ago for £10000. Work out the value now.
Answers
Given:
The value of car before two years = £10000
The value of the car decreases by 5% each year.
To find:
The present value of the car.
Solution:
The exponential decay model for present value is
[tex]y=a\left(1-\dfrac{r}{100}\right)^t[/tex]
Where, a is the initial value, r is the rate of decay and t is time in years.
Putting P=10000, r=5 and t 2, we get
[tex]y=10000\left(1-\dfrac{5}{100}\right)^2[/tex]
[tex]y=10000\left(1-0.05\right)^2[/tex]
[tex]y=10000\left(0.95\right)^2[/tex]
On further simplification, we get
[tex]y=10000(0.95)(0.95)[/tex]
[tex]y=9025[/tex]
Therefore, the present value of the car is £9025.
