You have to keep order of operations in mind.
1. Take care of the parentheses; distribute.
-3+6x-3=-20-8x
Simplified: 6x-6=-20-8x
2. Isolate the x variable.
Add 8x to both sides and add 6 to both sides.
14x=-14
3. Solve for x.
Divide by 14 on both sides.
x=-1
Answer c = (a-b)/d
Step-by-step explanation:
subtract b and divide by d
1. Slope = 7
2. x-intercept = 6/7 = 0.85714
3. y-intercept = 6/ - 1 = -6.00000
Rearrange:
Rearrange the equation by subtracting what is to the right if the equal sign from both sides of the equation:
7x-y- (6) = 0
Answer:
Ava's share = $20
Charlotte's share = $16
Step-by-step explanation:
15x + 12x = 36 : multiply each girl's age by same amount and adding gives $36
27x = 36 : add x terms
x = 36 / 27 : divide both sides of equation by 27
x = 4 / 3
Ava's share = 15x = 15 * 4/3 = 20
Charlotte's share = 12x = 12 * 4/3 = 16
Answer: N= 4/8
3/8+4/8= 7/8
