In one hour, 17 cars drive through an intersection. Two-fifths of the 17 cars fail to come to a complete stop at the stop sign.

Rasek [7]

Answer:

Step-by-step explanation:

When you have a number (17) and want to know some fraction (2/5) of that number, you should multiply the number by the fraction.

17 * (2/5)

= (17*2)/5

= 34/5

= 6.8

You can then round this number up --> about 7 cars.

X/2.4+39=239<br> show work

grin007 [14]

Answer: x = 480

Steps: x/2.4 + 39 = 239

Subtract 39 from both sides: x/2.4 + 39 - 39 = 239 - 39

Simplify: x/2.4 = 200

Multiply both sides by 2.4: x/2.4 × 2.4 = 200 × 2.4

Simplify: x = 480
