Answer:
x = -10/6 or - 5/3 (in lowest terms)
Step-by-step explanation:
To solve 2(x + 3) = -4(x + 1) for x:
Distribute 2 into (x + 3), and -4 into (x + 1):
2(x + 3) = -4(x + 1)
2x + 6 = -4x - 4
Add 4x to both sides:
2x + 6 + 4x = -4x + 4x - 4
6x + 6 = -4
Subtract 6 from both sides:
6x + 6 - 6 = -4 - 6
6x = -10
Divide both sides by -6:
x = -10/6 or - 5/3 (in lowest terms)
Correct Question: If m∠JKM = 43, m∠MKL = (8x - 20), and m∠JKL = (10x - 11), find each measure.
1. x = ?
2. m∠MKL = ?
3. m∠JKL = ?
Answer/Step-by-step explanation:
Given:
m<JKM = 43,
m<MKL = (8x - 20),
m<JKL = (10x - 11).
Required:
1. Value of x
2. m<MKL
3. m<JKL
Solution:
1. Value of x:
m<JKL = m<MKL + m<JKM (angle addition postulate)
Therefore:
Solve for x
Subtract 8x from both sides
Add 11 to both sides
Divide both sides by 2
2. m<MKL = 8x - 20
Plug in the value of x
m<MKL = 8(17) - 20 = 136 - 20 = 116°
3. m<JKL = 10x - 11
m<JKL = 10(17) - 11 = 170 - 11 = 159°
