Are these three different questions? if so:
1: add 19 to both sides to get a = 3 +19
answer: a = 22
2: multiply both sides by 7 to get y = 10 * 7
answer: y = 70
3: divide both sides by 5 to get g = 100/5
answer: g = 20
hope this helped! good luck :)
Answer:
1,045 applications
Step-by-step explanation:
Create a proportion where x is the number of applications they received:
= 
Cross multiply and solve for x:
7x = 7315
x = 1045
So, they received 1,045 applications
I'll focus on problem 19 and problem 22
============================================================
Problem 19
Answers:
-------------------------------
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
