Answer:
9/27 or 9 to 27
Step-by-step explanation:
First step is parentheses so subtract 1/4 from 1
(1-1/4) = (4/4 - 1/4) = (3/4)
After parentheses we perform exponent operations
(3/4)^2 = (3^2/4^2) = (9/16)
Finally, after exponent operations we perform multiplications
(1/3)*(9/16) = (3/16)
3(x-2)+4(2x-3)
Use distributive property
3(x)-3(2)+4(2x)-4(3)
=3x-6+8x-12
Combining like term
3x+8x-6-12
=11x-18. As a result, 11x-18 is another expression that equivalent for 3(x-2)+4(2x-3). Hope it help!
Answer:
13. y = -4x + 6
14. y = 1/2x - 2
Step-by-step explanation:
You want to put y on one side and the rest of the numbers on the other side. You can do this by adding or subtracting or dividing the numbers/variables on the left.
13.
4x + y = 6
subtract both sides by 4x
y = 6 - 4x
or rewritten as:
y = -4x + 6
14.
-3x + 6y = -12
add both sides by 3x
6y = 3x - 12
divide both sides by 6
y = 1/2 x - 2
