edgar and tim each wrote a correct number sentence to solve this problem.

megan finished a 6 mile bike race in 30 minutes. she biked each mile in the same amount of time. how many minutes did it take megan to bike each mile?

each boy wrote a different number sentence. edgar wrote: 30 ÷ 6 = .

which number sentence could tim have written to solve the problem?

a.
+ 6 = 30

b.
– 36 = 30

c.
× 6 = 30

d.
= 30 × 6

no this is a nonlinear negative

1st part is 64,000,000

2nd part 500,000

step-by-step explanation:

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
