Answer:

x = 12 6/7 or 90/7

Step-by-step explanation:

5x + 2x - 10 = 80

^^add you like terms (5x + 2x)

7x - 10 = 80

add -10 to both sides so it cancels out

7x = 90

divide 7 from both sides to get x by itself

x = 12 6/7

Benjamin has to wear a uniform to school. His uniform is made up of tan or blue pants and a blue or white collared shirt. Benjam
oee [108]

Explanation:

As his uniform is made up of tan or blue pants and a blue or white collared shirt.

So, there are possibly four combinations which are as follows:

  • tan pants/blue shirt
  • tan pants/white shirt
  • blue pants/blue shirt
  • blue pants/white shirt

As Benjamin carries an extra piece of white shirt. So, he has a little bit better than 25% chance of wearing his favorite combination.

So,

  • Probability of getting tan pants = 2/4 = 1/2
  • Probability of getting white shirt = 3/5

The probability of getting both can be computed by simply multiplying 2/4 and 3/5.

So,

  • Probability of getting both = 1/2 × 3/5 = 3/10 ⇒ 30%
