Answer:

Step-by-step explanation:

Set up a proportion.

3/25 = x / 20      Notice that both times are in the denominators. Be sure you always set up a proportion that way. Like units in the denominator. Like units in the numerator.

Cross multiply

3 * 20 = 25 * x                        Combine

60 = 25x                                 Divide by 25

60/25 = x

x = 2.4 miles in 20 minutes.

Answer:

In 20 minutes, Trey would run 2.4 miles.

Step-by-step explanation:

20x = 25

x = 4/5

This means we multiply the number by 0.8

3 * 0.8 =

3/25 = 2.4/20

2.4 miles / 20 minutes

1. 2(H-8)-h=h-16
podryga [215]

(1) C and (2) D

(1)

distribute the left side of the equation

2h - 16 - h = h - 16 ( simplify left side )

h - 16 = h - 16

Since both sides are equal, any value of h will make the equation true.

Hence there are infinitely many solutions to the equation → C

(2)

3 + 6z = 13 + 6z ( subtract 6z from both sides )

3 = 13 ← not possible

Hence there are no solutions to the equation → D

Can Someone help me plz????

Answer:

4. C

5. 7

6. 3

Step-by-step explanation:

Four:

You have to multiply both of them. Just easy math!

Five:

This one is more complicated. You can see that it is asking you to plug in for a,

F(3):

f(3)= 4(3)-5

f(3)=12-5

f(3)=7

F(1.25):

f(1.25)=4(1.25)-5

f(1.25)=5-5f(1.25)=0

So now just subtract the answers. 7-0 equals 7.

Six:

Just look at the graph and see what number corresponds with y(6), or the 6 on the y axis. It appears to be three.

Have a nice day! Hope this helps. Don't forget to mark brainliest!
