3x+ 32 +7x - 22 = 180

Sedaia [141]

Add 3x and 7x because they’re on the same and when you added it you’ll get 10x and than do 32+-22 and you’ll get 10 because 32-22 is 10 and you subtract the 10 to 180 and you’ll get 10x=170 and divide 170 by 10x to get x by itself when you divided you’ll get x=17 and that’s the answer.

Answer:

The probability that the person will not be a senior

P(E⁻) = 1 - P(E)

= $1- \frac{5}{9} = \frac{4}{9}$

Step-by-step explanation:

Explanation:-

Given A high school club has 10 members who are seniors and 8 members who are juniors

n(S) = 10 + 8 = 18

If a member is randomly selected to be the club president

Let 'E' be the event that the person will be a senior

The probability that the person will be a senior

$P(E) = \frac{n(E)}{n(S)}$

$P(E) = \frac{n(E)}{n(S)} = \frac{10}{18} = \frac{5}{9}$

The probability that the person will not be a senior

P(E⁻) = 1 - P(E)

= $1- \frac{5}{9} = \frac{4}{9}$

Manuel is making cookies for the holidays. Each batch of cookies he will make requires 3/4 cup of sugar. He has a total of 2 5/8

vichka [17]

Set up proportions.
3/4 cups → 1 batch
x cups → 2 batches
x = 2(3/4) = 6/4 = 1 1/2 cups
3/4 cups → 1 batch
y cups → 9 batches

y = 9(3/4) = 6 3/4 cups
