Given :
Evaluate the equation.
2x – 4(x – 2y) + 6y = ?When x = 5 and y = 2 then,
2x – 4(x – 2y) + 6y
= 2(5) – 4[(5) – 2(2)] + 6(2)
= 10 – 4(5 – 4) + 12
= 10 – 4*1 + 12
= 10 – 4 + 12
= 22 – 4
= 18

5x - 14 = 3(3x + 6) + 5
Answer:
x= -9.25
Step-by-step explanation:
5x - 14 = 3(3x + 6) + 5
5x - 14 = 9x + 18 + 5.......distribute
-4x = 37.............move values and combine like terms
x= -9.25.............divide both sides by -4

Explain your answer using words, and show your work using division of fractions.
Answer:=> 10 months
Given :
Step-by-step explanation:
Given :
1 / 4 inches = 1 month
Find :
5 / 8 inches = ? months
According to the question :
1 month = 1 / 4 inches
5 / 8 inches = ' x ' months
=> ( 5 / 8 ) / ( 1 / 4 ) = x
=> ( 5 / 8 ) × ( 4 / 1 ) = x
=> ( 5 × 2 ) / 1 = x
=> 10 / 1 = x
=> x = 10.
So, it takes 10 months.
Answer:
it would be 5 months for his hair to grow 5 inches.
Step-by-step explanation:
well, if his hair grows 1 inch per month, and it take 5 months for his hair to grow.

1 year = 12 months
3/4 year =
Answer:
3/4 year = 9
Step-by-step explanation:
To find 3/4 of a year you first need to find 1/4 of a year so you do 12/4 and get 3. Now we know that 1/4 of a year is 3 months so you just multiply that by 3 to get 9. So 3/4 of a year is 9 months.
I hope this helps!
Your answer to 3/4 of a year is 9 months

How Many Solutions Does 6 + [tex]\frac{x}{5}[/tex] = [tex]\frac{x}{5}[/tex] - 5 - [tex]\frac{3x}{10}[/tex] Have?
A. One solution
B. Two solutions
C. No solutions
D. Infinitely many solutions
Answer:
A. One solution
Step-by-step explanation:
6 + x/5 = x/5 - 5 - 3x/10
Cancel equal terms on both sides.
6=-5-3x/10
Multiply both sides of the equation by 10.
60=-50-3x
Move the variable to the left-hand side and change the sign.
60+3x=-50
Move the constant to the right-hand side and change the sign.
3x=-50-60
Calculate the difference.
3x=-110
Divide both sides by 3.
x=-110/3
=-36 2/3
Meaning one solution.
Hope this helps :)
