The given equations satisfy the given conditions. There are
2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
Answer: 30°
Step by step explanation:
1) Supplementary angles add up to 180°
2) (2x+10)+(5x-40)=180
3) solve for x
4) x=30
Answer:
A
Step-by-step explanation:
Taking the square root of both sides.
Answer:
A) 32, 40, 48, 56, 64, 72, 80
B) y-axis goes 4, 8, 12
x-axis goes 4, 8, 12, 16, 20
