Answer:

y = 50

Step-by-step explanation:

Since 20 is even with 100, all we have to do is multiply both sides by 5.

(5 × 20%) × y = 10 × 5

y = 50

Please give me brainliest :)

If 10 is 20% of a number, we can multiply it by 5 to get the original number.

So 10 * 5 = 50, and 20% of 50 is 10.

I hope this helps! :)

I'll focus on problem 19 and problem 22

============================================================

Problem 19

Answers:

x = 87
x+15 = 102

-------------------------------

Explanation:

The horizontal lines are parallel. Note the arrow markers along the interior portion of the lines. These similar markers tell us how the lines pair up to be parallel to one another.

Since the horizontal lines are parallel, this means the angles in question are congruent. They are corresponding angles.

x+15 = 102

x = 102-15

x = 87

Which leads to

x+15 = 87+15 = 102

============================================================

Problem 22

Answer: y = 27

-------------------------------

Explanation:

We have a pair of alternate exterior angles. They are congruent due to the parallel lines.

Let's solve for y.

7y-55 = 3y+53

7y - 3y = 53+55

4y = 108

y = 108/4

y = 27

Tanner collected 360 cans and bottles while fundraising for his baseball team. This was 40% of what Reggie collected. How many c

Vanyuwa [196]

The amount Reggie collected is equal to x
$\frac{360}{.4}= \frac{x}{1}$

$x = \frac{360}{.4} = \frac{360}{ \frac{4}{10} } = \frac{360*10}{4} = 900$
