Answer:
4y + 24
Step-by-step explanation:
4(y + 6) = 4y + 24
With these values x = 14.
In order to find this, we must note that LM will be half of KM (since L is the midpoint). Because we know this, we also know that we can multiply LM by 2 and set equal to KM.
2LM = KM
2(2x + 4) = 5x - 6
4x + 8 = 5x - 6
8 = x - 6
14 = x
Answer:
3a-1
Step-by-step explanation:
Substitute
3(a+2)-7

3a-1
Answer:
Step-by-step explanation:
12x - 2 + 20x - 10 = 180
32x - 12 = 180
32x = 192
x = 6
12*6 - 2
72 - 2 = 70
the solution is b
Answer:
R1: Given
R2: Subtraction Property of Equality
R3: Distribute Property
R4: Addition Property of Equality
R5: Division Property of Equality
Write a paragraph proof for the following conjecture: m∠1 + m∠2 = m∠4
Prove: m∠3 + m∠1 + m∠2 = 180°
Given: ∠1 + ∠2 = ∠ 4
∠4 + ∠3 must be 180° because they are supplementary
If ∠4 + ∠3 is 180, and ∠1 + ∠2 = ∠4, you can substitute ∠4 in the first equation for ∠1 + ∠2.
Hence, we arrive at the answer ∠1 + ∠2 + ∠3 = 180.
