Solve 4(-2x + 7) = 24 for x
tamaranim1 [39]

Answer:

x = 1/2

Step-by-step explanation:

brainlest please

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    4*(-2*x+7)-(24)=0

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 4 • (7 - 2x) -  24  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  4 - 8x  =   -4 • (2x - 1)

Equation at the end of step  3  :

 -4 • (2x - 1)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    -4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    2x-1 = 0

Add  1  to both sides of the equation :

                     2x = 1

Divide both sides of the equation by 2:

                    x = 1/2

There are 30 students in an art class. Fourteen of the students are girls.
DedPeter [7]

Answer: B

Step-by-step explanation: To get the boys part of the ratio you will have to subtract 30 students and 14 students that are girls because all together there are 30 students and since we only know that 14 of them are girls that leaves the rest of the students boys. 30 - 14 = 16  so now we know how many boys there are. 16:14 can be reduced by 2 and that equals to 8:7.

Hope this helps!
