Answer: 7x + 20 = 90
Step-by-step explanation:
Let x be the number of children she babysat.
7x + 20 = 90
I think the answer is this
2x-4x+1=0
Combine like terms
-2x+1=0
Subtract 1 both sides
-2x=-1
Divide by -2 both sides
x=-1/2
1/3b-1/3
factor out 1/3
1/3(b-1)
hope this helps
Answer:
1.4
Step-by-step explanation:
Answer:
y = 2x
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Find slope <em>m</em>
2x - y = -4
-y = -2x - 4
y = 2x + 4
Since the 2 lines are parallel, they have the same slope.
Step 2: Define variables
Slope <em>m</em> = 2
Origin (x-int and y-int) (0, 0)
Step 3: Write parallel linear equation
y = 2x + 0
y = 2x
