1/2, 3/4, 9/10, 4/2
I don't think this was a middle school question but whatevs
2(x - 16) + 12 = 30
2x - 32 + 12 = 30
2x - 20 = 30
2x = 30 + 20
2x = 50
x = 50/2
x = 25 <=== the temp was 25 at midnight
Answer:
add the 2 equations together
Step-by-step explanation:
i was in class when I heard this so it should be correct
Answer:
The value of x = 18
===============================
Step-by-step explanation:
Given m∠A = 2x + 4
m∠B = 6x - 58
The exterior angle at C = 5x
We should know that:
The exterior angle at C = m∠A + m∠B
∴ 5x = (2x + 4) + (6x - 58)
Solve for x
∴ 5x = 2x + 4 + 6x - 58
∴ 5x = 8x - 54
∴ 5x - 8x = -54
∴ -3x = -54
∴ x = -54/-3 = 18
<u>So, the value of x = 18</u>
Answer:
5x^2 - 4r - 3
hope this will hel you :))
