Solve using the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .
3(8 - 2) + 4 = 22
Parentheses...
(15 - 6)² ÷ 3 - 3³
15 - 6 = 9
(9)² ÷ 3 - 3³
Exponent....
9² ÷ 3 - 3³
In this case you have two exponents. Always apply the steps from left to right
9² ÷ 3 - 3³
9² = 81
81 ÷ 3 - 3³
3³ = 27
81 ÷ 3 - 27
Division...
81 ÷ 3 - 27
81 ÷ 3 = 27
27 - 27
Subtraction...
27 - 27 = 0
0
<u>Your mistake: </u>
You subtracted 3 - 27 before dividing 81 by 3. Remember that according to the rules of PEMDAS division must come before subtraction

Answer:
3 unit
Step-by-step explanation:
3/4 x 4 = 12/4 = 3
56 + 90 = 146 kilometers
4 + 2 = 6 hours
rate = 146 km / 6 hour
= 24.333 km / hour
Answer:
-17
Step-by-step explanation:
3x-7=4x+10
Add 7 to both sides & simplify
3x-7=4x+10
+7 +7
3x=4x+17
Subtract 4x from both sides & simplify
3x=4x+17
-4x -4x
-x=17
*Negative x equals -1*
Divide both sides by -1 & simplify
