Answer:
59
Step-by-step explanation:
The answer is 59 because when you add 24 and 7 it is 31 and 31 +59 makes a 90° angle.
Answer:
The solution to this system is (4, 1/6).
Step-by-step explanation:
Please separate these two equations for clarity. I like to write them in column format:
2.5y + 3x = 27
5x – 2.5y = 5
---------------------
8x = 32, and x = 4.
Subbing 4 for x in the second equation yields 5(4) - 2.5y = 5.
Then 20 - 2.5y = 5, or 15 = 2.5y. Solving for y, we get y = 1/6.
The solution to this system is thus (4, 1/6).
1) C. 100
a pentagon has 540 degrees
130 + 130 + 90 + 90 + x = 540
440 + x = 540
x = 100
2) C. 169
a hexagon has 720 degrees
151 + 135 + 115 + 75 + 75 + x = 720
551 + x = 720
x =169
Answer:
B, C, A.
Step-by-step explanation:
A = C + 3A = C + 3
A = C + 3
A = C + 3A
C + 3A = C + 3
3A = 3
A = 1
A = C + 3
1 = C + 3
C + 3 = 1
C = -2
B = 2C
B = 2(-2)
B = -4.
So, from least to greatest, B = -4, C = -2, and A = 1.
Hope this helps!
