$\Large\boxed{\tt Answer:~2 ~dollars}$

$\tt Step-by-step~explanation:$

See how many times 15 can go into 120.

$\tt \frac{120}{15} =8$

If 15 • 8 is 120, then the cost would have to multiply by 8.

$\tt 0.25*8= 2$

It costs $2.00 to use the dryer for 120 minutes.

We can also use the equation to help. We plug in 120 for m and solve.

$\tt 0.25(20)=30\\30 \div 15 = 2$

We still end up with the same result: $2.00 for 120 minutes.

Find a number which decreased by 12 equals 3 times it’s opposite

-BARSIC- [3]

Answer:

The number is 3.

Step-by-step explanation:

To find : A number which decreased by 12 equals 3 times it’s opposite ?

Solution :

Let the number be 'x'.

It's opposite is '-x'.

A number which decreased by 12 equals 3 times it’s opposite

i.e. $x - 12 = 3(-x)$

Solving the equation,

$x-12=-3x$

$x+3x=12$

$4x=12$

$x=\frac{12}{4}$

$x=3$

Therefore, the number is 3.

Abby rode the Metro bus 4 miles farther than James rode. The sum of their distances traveled is 28 miles. How far did James ride

ohaa [14]

A. define the variables : a = abby's miles, j = james' miles

b. a = j + 4......j = a - 4

c. a + j = 28
a = j + 4

d. (j + 4) + j = 28
2j + 4 = 28
2j = 28 - 4
2j = 24
j = 24/2
j = 12

a = j + 4
a = 12 + 4
a = 16

e. check..
a + j = 28
16 + 12 = 28
28 = 28 (correct)

solution is : abby's miles (a) = 16
james' miles (j) = 12

The graph of the parent function f(x) = x3 is translated to form g(x) = (x – 2)3 – 3. Which is the graph of g(x), the translated

Nookie1986 [14]

f(x) + n - shift a graph of f n units up

f(x) - n - shift a graph of f n units down

f(x + n) - shift a graph of f n units left

f(x - n) - shift a graph of f n units right.

f(x) = x³, g(x) = (x - 2)³ - 3 = f(x - 2) - 3

2 units right and 3 units down.
