Question

Need help number 18,19

Answer 1

18) Seven less than the product of a number z and 3 is equal to 4

Product of a number z and 3 ⇒ 3z

Seven less than^ ⇒ 3z - 7

Equal to 4 ⇒ = 4

3z - 7 = 4

19) Make an equation for this problem. Your equation will look like:

d + 132 = 468, where d + 132 is the distance she drove on Monday and 468 is the distance she drove on Tuesday.

Solve the equation for d by subtracting 132 from both sides.

d = 336

The truck driver drove 336 miles on Monday, so that means she did not drive 600 miles on Monday.

Answer 2

18) 7 less than the product of a number z and 3 is equal to 4.

$7\ less\ than = -7 \\ Product = \times \\ Product\ of\ a\ number\ z\ and\ 3 = 3z \\ equal\ to\ 4 \rightarrow =4$

That gives you:

$3z - 7 = 4$

18) 3z - 7 = 4

$d+ 132 = 468$

d + 132 is the distance she drove on Monday. 468 is the distance she drove on Tuesday.

Subtract 132 from both sides to solve for d:

$d+132 - 132 = 468 - 132 \\ d = 336$

The truck driver drove 336 miles on Monday. That means she did not drive 600 miles on Monday.
