slamgirl [31]

Answer:

x= 3

Step-by-step explanation:

1. -5(3) + 2 = -13

2. -15 + 2 = -13 A positive times a negative will always equal a negative

3. -13 = -13 Whenever you add anything to a negative number, the

number becomes smaller

Ex: -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, ...........

Although the number itself becomes smaller, its value

becomes bigger

Hope this helps.

Draw and write to explain how these two problems are different 35-15=. And 43-26=.

Rashid [163]

35-15 is 20. and 43-26 is 17. These two are different because you are regrouping in the 2d problem, as in the first, you just subtract.

if the measure of <BEC is (2x+3)° and x=30, which expression could represent the measure of <AED?

Maurinko [17]

Answer:

The answer is 3x-27

Step-by-step explanation:

If the angles are vertical from each other it means they are congruent. 2x+30 is 63, you plug in the x, 2(30)+30. You do that to the second one and also get 63, 3(30)-27. Therefore 3x-21 is the answer.

To estimate the number of people in Springfield, population 10,000, who have a swimming pool in their backyard, 250 people were

Andrei [34K]

Answer:

2400 people

Step-by-step explanation:

Let x be the number of people who had a swimming pool in the population of 10,000,

Thus, the ratio of people who had swimming pool to the total population = $\frac{x}{10000}$

Since, out of 250 people 60 had swimming pool,

So, the ratio of the people who had swimming pool to the total population = $\frac{60}{250}$

$\because \frac{x}{10000}=\frac{60}{250}$

$\implies 250x=600000$

$\implies x=\frac{600000}{250}=2400$

Hence, 2400 people in the city might one expect to have a swimming pool.

First option is correct.
