Evaluate the expression 2×(d+62)−20÷4 when d=4 .

2 x 64 -20/4             do (  ) first (4 +64) = 68

136 x 2 - 20/4                   multiply next 2 x68 =136

136 -5                           division next 20/4

131                                  then subtract 136 -5 = 131      PEMDA rule :)

Step-by-step explanation:

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
