Kens prediction temperature for April 7C. His prediction for May is 2C higher than April. He use the number line to solve the problem, starting at zero, moving right to seven, and then moving to units to the left. Explain Ken's error

Step-by-step explanation:

Given that:

Ken's prediction temperature for April 7C.

His prediction for May is 2C higher than April.

He attempts to use the number line to solve the problem.

On a number line, we have the origin at a given point zero, the positive x-axis to the right side, and the negative x-axis to the left side.

So, if Ken's starts from zero and move right to seven and the move units to the left, the error he made was moving 2 units to the left because he supposed to have continued in the right direction by moving 2 units forward. This is because moving to the left side will showing a decrease in the temperature by -2° C and he intends to have 2° C.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
