Zahra wants the equation below to have an infinite number of solutions when the missing number is placed in the box. - 3) + 2x = -(x - 5) + 4 which number should she place in the box? –3 –1 1 3

The answer is -3.

To find this, we simply have to solve the equation and leave only the blank and the parenthesis that it is with on the right side. Then we can divide by the parenthesis. The work for this is done for you below.

(x - 3) + 2x = -(x - 5) + 4 > Distribute the -1 to the parenthesis.

(x + 3) + 2x = -x + 5 + 4 > Simplify

(x + 3) + 2x = -x + 9 > Subtract 2x from both sides

(x + 3) = -3x + 9 > Divide both sides by x + 3

= -3.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
