Answer:
<u>x = 14</u>
Step-by-step explanation:
4x + (2x + 6) = 90
6x + 6 = 90
subtract both sides by 6:
6x + 6 <em>- 6 </em>=<em> </em>90 <em>- 6</em>
6x = 84
divide both sides by 6
6x/6 = 84/6
x = 14
double check:
4*14 + (2*14 + 6) = 90
56 + 28 + 6 = 90

Heer is the complete question:
A factory makes car batteries. The probability that a battery is defective is 1/14. If 400 batteries are tested, about how many are expected to be defective?
A) 14
B) 371
C) 29
D)35
Probability that a battery is defective = 1/14
Number of batteries tested= 400
Expected number of defective batteries= Probability that a battery is defective × Number of batteries tested
= 1/14 × 400
= 400/14
= 28.57
= 29 Approximately
