8/10 of a dollar is the correct answer
Answer:70
Step-by-step explanation:
10^2 =100
-2(10+15) = -2(15)=-30
100-30= 70
You can set up two equations from the information given. I will set them up for you:
32 = 4x + 2y
36 = 5x + 2y
Let's solve the first equation to come up with a value for y.
32 = 4x + 2y
32 - 4x = 2y
16 - 2x = y
Now we plug y into the other equation.
36 = 5x + 2(16-2x)
36 = 5x + 32 - 4x
4 = x
Now we have our real x value and we can plug it into the first equation.
32 = 4(4) + 2y
32 = 16 + 2y
16 = 2y
8 = y
Since x = 4 and y = 8, you get the final coordinates of (4,8).
Your answer is the second statement provided above.
When two adjacent angles form a straight line, they are called linear pair. They add up to 180.
j + 102 = 180
j = 180 - 102
j = 78
