Answer:
1 hour
Step-by-step explanation:
25min=1 poster for the shop owner
25×4=100

Answer:
Step-by-step explanation:
-2x + 6 = -6
-2x = -12
x = 6
Answer:
X + X + 1 + X + 2 = 72
3X + 3 = 72
3X + 3 - 3 = 72 - 3
3X = 69
3X/3 = 69/3
X = 23
Step-by-step explanation:
To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side.
About 151. That seems pretty close. If it is incorrect, sorry.
Answer:
Given the expression -3 - 4(2x- 3) the correct solution is -8x + 9.
Step-by-step explanation:
Andy wrote -14x + 21, so his error was to do de substraction (-3 -4) and then distribute -7(2x-3) = -14x+ 21.
Sylvie wrote -8x -6. Her error was to multiplied -4 only for 2x,
then -3 - 4(2x -3) = -3 -8x -3 = -8x -6.
