X+x=15 combine like terms on left side
2x=15 divide both sides by 2
x=7.5
Step-by-step explanation:
A. 2(10)-(-10)
20 -(-10) -------> (-)×(-) =(+)
20 + 10
30
B.29 + 1
30
The LCM (least common factor) of 12 and 27 is the number: 3
Answer:
x>-4
Step-by-step explanation:
divide both sides by -6 without changing the sign
Answer:
y = -5x + 7
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Define
5x + y = -2
Random point (2, -3)
Step 2: Rewrite
y = -5x - 2
m = -5
Step 3: Write parallel line
y = -5x + b
-3 = -5(2) + b
-3 = -10 + b
7 = b
y = -5x + 7
