40 mph

a to b's distance = 180 miles

7:30 - 12pm = 4.5 hours (time)

Answers

Answer:

s = 16

Step-by-step explanation:

[tex]\frac{s}{4} +12=16[/tex]

step 1 subtract 12 from each side

12 - 12 cancels out

16 - 12 = 4

now we have [tex]\frac{s}{4}=4[/tex]

step 2 multiply each side by 4

[tex]\frac{s}{4} *4=s[/tex]

4 * 4 = 16

Find the values of x and y that make each quadrilateral a parallelogram. Show your work.

Answers

Step-by-step explanation:

A. to make the quadrilateral a parallelogram, we have:

7y + 5 = 8y - 4

112 = 10x - 8

<=> y = 5 + 4

120 = 10x

<=> x = 12

y = 9

B.we have:

17 = 4x + 5

63 = 8y - 1

<=> 12 = 4x

64 = 8y

<=> x = 3

y = 8
