8 0

Answer:

no solution

Step-by-step explanation:

Given

2(x - 3) = 2x + 5 ← distribute parenthesis on left side

2x - 6 = 2x + 5 ( add 6 to both sides )

2x = 2x + 11 ( subtract 2x from both sides )

0 = 11 ← not possible

This indicates the equation has no solution

If Adrianna can read 7 pages in 10 minutes. At this rate, how many page can she read in 25 minutes?
lesya692 [45]

3.5 : 5

7 : 10

14 : 20

17.5 : 25

At that rate, she can read 17.5 pages in 25 minuets.

Divide both 7 and 10 by 2, which gets 3.5 and 5

5 * 5 = 25

5 * 3.5 = 17.5

Therefore, in 25 minuets, she can read 17.5 pages.

Lisa is in charge of planning a reception for 3600 people. She is trying to decide which snacks to buy. She has asked a random s
Olenka [21]

Answer:

The expected number of the people at the reception whose favorite snack will be chips is 1152

Step-by-step explanation:

Given

The data in the above table and

Reception = 3600

Required

Predict the number of the people at the reception whose favorite snack will be chips.

The first step is to determine the total number of samples;

Total = Brownies + Cookies + Chips + Other

Total = 32 + 22 + 56 + 65

Total = 175

The next step is to determine the fraction of people whose favorite is chips

Fraction = \frac{Chips}{Total}

Fraction = \frac{56}{175}

The product of the above fraction and the expected number of people in the reception is the solution to this question;

Expected\ Number = \frac{56}{175} * 3600

Expected\ Number = \frac{56* 3600}{175}

Expected\ Number = \frac{201600}{175}

Expected\ Number = 1152

<em>Hence, the expected number of the people at the reception whose favorite snack will be chips is 1152</em>
