Answer:
x = 29, C
Explanation: We are given that total angle is 90°, or a right angle. This means that the two complementary angles must equal 90° together.
Create the equation:
2x - 4 + x + 7 = 90
Solve algebraically:
3x + 3 = 90
3x + 3 - 3 = 90 - 3
3x = 87
3x / 3 = 87 / 3
x = 29 or C
Answer:
15 houses
Step-by-step explanation:
1/3 * 72 = 24
5/8 * 24 = 15
Answer:
(5, 0)
Step-by-step explanation:
For the first line, we can isolate x by subtracting 5y on both sides.
x=5-5y.
Now we can use substitution on the second line!
-(5-5y)+6y=-5
= -5+5y+6y=-5
=-5+11y=-5
=11y=0
y=0
We subsitute y for the first line,
x+5(0)=5
x+0=5
x=5
We can check our work by plugging in x and y
5+5(0)=5 ✔
-5+6(0)=-5 ✔
