Answer:
x = 1
Step-by-step explanation:
-5x-(-7-4x)-2(3x-4)
-5x + 7 - 4x - 6x + 8 First step is to factor all the numbers out so you have no parenthesis. In this case -(-7 just turns into + 7 because two negatives equal a positive. As well as -2*3x and -2*-4 which gives you -6x + 8.
-15x + 15 In this step you combine like terms.
-15x = -15 Next you move the whole number to the other side of the equation by subtracting it from both sides.
x = 1 Finally you divide -15 by -15 to get x by its self.
I think the answer is 1.5 when you flip the 36/45.
I hope this helps you
-7.x^3=2.7.9
x^3=-18
x=i.(3square root of 18)

Answer:
B would be correct.
Step-by-step explanation:
You have to subtract the 1/3 and 1/4 by the whole pizza (1) otherwise you never had a whole pizza according to your equation. By doing 1-1/3 you solve for the amount left on Monday, and when you subtract 1/4 from the number you just got, you have solved for the total amount left on Tuesday.
1-1/3=2/3
2/3-1/4= 2/3 * 4/4 - 1/4 * 3/3 =
8/12-3/12= 5/12 of a pizza left
