Set up a system of equations using the sum and difference equation.
x + y = 180 <em>definition of supplementary angles</em>
+ <u>x - y = 35</u>
2x = 215
x = 107.5
x + y = 180 ⇒ 107.5 + y = 180 ⇒ y = 72.5
Answer: 107.5 and 72.5

Answer:
399 minutes a month
Step-by-step explanation:
As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.
The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).
The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.
Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.
Answer:
D.
Step-by-step explanation:
the graph has a y intercept of -3
try substituting any point in one of the equations that fit the graph in this one that is D.
try(1,1)
1<1-3
1<-3
it is false so shade the outside of the graph

Answer:
x = 5
Step-by-step explanation:
Given
8 = 
Multiply both sides by 3 to clear the fraction
24 = 5x - 1 ( add 1 to both sides )
25 = 5x ( divide both sides by 5 )
x = 5
