Answer:
y=45-3x
Step-by-step explanation:
we want y, which is the number of hours left. to find this, we take:
hours left=total # of hours required - hours worked/day
so:
y=45-3x
(because x could be any number: 2 days, 3 days, etc.)
Answer:
3x - 27 = 51
x equals 26
Step-by-step explanation:
3(dollars) times x(number of shirts sold). Then you subtract the amount she spent on supplies($27) and you get 51, the total profits she made.
Answer:
I only know the first 1 sorry but here is the answer y=-3/4+2
Step-by-step explanation:
3x+4y=8
-3x -3x subtract -3x to get on the right side
4y=-3x+8
/4 /4 /4 divide by 4 on both sides
y=-3/4x+2 since 4 can't go into 3 you leave as a fraction -3/4x
UPDATE: I found the answer to number 4
The answer is y=-11/7x+8
-11x-7y=-56
+11x +11x Add 11x
-7y=11x-56
/-7 /-7 /-7 Divide by -7 on both sides
y=-11/7x+8 Since -7 can't go into 11 you leave as a fraction -11/7x
ANOTHER UPDATE: I found the answer to number 7
-14x+y=7
+14x +14x Add 14x to both sides
y=14x+7 Since y doesn't have a number your answer is as shown
