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
$1 = 2 weeks
-
<u>Multiply by 800:</u>
$1 x 800 = 2 x 800 weeks
$800 = 1600 weeks
-
Answer: You need <u>1600 weeks </u>to get $800
Your breaking the problem down.
8 x (40 + 7)
You notice how in the second part of the equation, the (8 x 7) the 40 is not there?
Your answer will be 8 x (40 + 7) = (8 x 40) + (8 x 7)
Answer:
Step-by-step explanation:
Minnesota: 86900 square miles
Wisconsin: 65000 square miles.
Net form
86900 - 65000 = 21900 square miles.
Standard Form
86900/65000 = 1.33
Minnesota is 1.33 times as large as Wisconsin.
Scientific notation
1.33 * 10^0
Minnesota is still 1.33 times as large as Wisconsin
Answer:
Its option A
Step-by-step explanation:
P=2l+2w
P=2(l+w)
P/2=l+w
P/2-l=w
(P-2l)/2=w
