choices
70
110
129

110

Step-by-step explanation:

Step one- Plug in the value of a &b so the equation should look like this

10 x 9 + 5(6-2)

Step two- Apply the PEMDAS rule so in this case we are going to o the parenthesis. 6-2=4

Rewrite the equation like this 10 x 9+5 x 4

Step three- there are no exponents so we are going to multiply and divide from left to right 10 x 9=90 and 5 x 4 = 20

Rewrite the equation 90+20

Step 4 Add and subtract from left to right

Your final answer is 110

Hope this helped :)
