Remember PEMDAS
first add -3p^2 and 7p^2 to get 4p^2.
next add 8p^2 and 4p^2 to get 12p^2
12p^2 is your answer
Answer:
A. 1.2x = 78
B. x = 65
Step-by-step explanation:
Just informally, first:
x is the number that we don't know. 120% of that number is a number BIGGER than that number. 120% of x is 78. So 78 is BIGGER than the number that we don't know.
120% of x = 78
Change 120% to a decimal by moving the decimal two places to the left. Multiply.
1.2x = 78
To solve, divide both sides by 1.2
x = 78/1.2
x = 65
