Answer:
1. 90
2.60
3.30
4. 40
5. 80
6. 60
7. 30
8. 30
9. 120
Total for all triangles=180
Step-by-step explanation:
In all the problems, you have to solve for y. This can be done because the three angles are supplementary For example, in the first diagram, you have:
3y+2y+y=180
6y=180
y=30
It's fairly easy to solve from there. Just more multiplying and subtracting.
Im pretty sure it’s $36.50 because you divide 78,475 by 2,150
Answer:
2^2
Step-by-step explanation:
2^-3/2^-5
We know that a^b / a^c = a^(b-c)
2^-3/2^-5 = 2^( -3 - -5) = 2^(-3+5) = 2^2
B = -16
m = (-15-(-16))/18-0 = 1/18
y= 1/18x - 16
Answer: y=-2/5x+2
Solving Steps:
2x+5y=10 - Move the variable to the right
5y=10-2x - Divide both sides by five
y=2-2/5x - Reorder the terms
y=-2/5x+2
