The answer should be 37
2(x+8) = 3(x-7)
distribute
2x+16 = 3x-21
Subtract 2x from both sides
2x+16-2x = 3x-21-2x
16 = x-21
Add 21 to both sides
16+21 = x-21+21
-2x + 7 and 0.5x - 5 are both equal to y, so they must be equal to each other.
-2x + 7 = 0.5x - 5
2.5x = 12
x = 4.8
Answer: x=8
Step-by-step explanation:
Since we are given that ∠ABC and ∠DBC are complementary angles, we know that adding them together should give us 90°. We can use this to solve for x.
6x+13+4x-3=90 [combine like terms]
10x+10=90 [subtract both sides by 10]
10x=80 [divide both sides by 10]
x=8
Now, we know that x=8.
Answer:
2 * ? =
OR
? * 2 =
Step-by-step explanation:
The given expression is:
divided by 2.
