y - 90 - 1/9 = 12.45 Step-by-step explanation: i think so if im incorrect
Answer:
The answer to your question is 900 black and white copies
Step-by-step explanation:
Data
9 black and white copies for every 2 colored
printed 200 color copies
black and white copies = ?
Process
This is a proportion exercise
BW : C :: bw : c
9 : 2 :: bw : 200
bw = 200(9) / 2
bw = 1800 / 2
bw = 900 copies
Two supplementary angles when added together need to equal 180 degrees.
Let the first angle = X
The second angle would then be X - 152
Add them together to equal 180:
X + X - 152 = 180
Simplify:
2X -152 = 180
Add 152 to each side:
2X = 332
Divide both sides by 2:
X = 332 / 2
X = 166
The first angle = X = 166 degrees.
The second angle = X - 152 = 166 - 152 = 14 degrees.
The angles are 166 and 14
