Answer:
17. 11x - 11y or 11x + (-11y)
18. -7.52 - 2.8 or -7.52 + (-2.8)
19. 41x - 21y - 6
20. -3y -8xy
Step-by-step explanation:
17. Use the distributive property.
18. Use the distributive property to multiply each number inside the parentheses by 0.4
19. Multiply each number inside the parenthese by 7.
20.Multiply each term in parenthese by y.
Answer:
1966600 items must be produced in other to profit $3933
Step-by-step explanation:
from the equation y = 0.002x -0.20
where y is the profit in dollars
and x is the number of items
then to get the number of item to be produced in other to profit $3933 ?
will be by substituting $3933 for y in the equation and solving for x,
3933 = 0.002x - 0.20
Firstly you will add 0.20 to both sides, which will be
3933 + 0.20 = 0.002x - 0.20 + 0.20
3933.20 = 0.002x
then we will divide both sides by 0.002
3933.20 / 0.002 = 0.002x / 0.002
therefore, x = 1966600
18+6x?= 168
try taking away the 18 and 6 then dividing it
