Answer:
x = 80 degrees
Step-by-step explanation:
y degrees = 180 - 55 - 45 (Angles in a triangle add up to 180 degrees)
y degrees = 80 degrees
x = y (Vertically opposite angles are equal)
So,
x = 80 degrees
Answer:
The solutions are the points (-3,0) and (-1,-2)
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system of equations by graphing
The solution of the system of equations are the intersection points both graphs
The solutions are the points (-3,0) and (-1,-2)
see the attached figure
Let b be the number of books in a box. Then we can say that the total number of books is equal to the number of boxes times the number of books per box.
7b=126 divide both sides by 7
b=18
So there are 18 books per box.
Solve your equation step-by-step.
2s+s+12=132
Simplify both sides of the equation.
2s+s+12=132
Simplify:
3s+12=132
Subtract 12 from both sides.
3s+12−12=132−12
3s=120
Divide both sides by 3.
3s/3 = 120/3
s=40
Answer:
Slope=2 (B)
Step-by-step explanation:
Find 2 points first.
(2,1) and (0,-3)
use y2-y1/x2-x1 formula
-3-1/0-2
-4/-2=2
