Simplify 18.03 – 3(12.7 + 8.06) ÷ 2.

Answers

Answer:

−13.11

Step-by-step explanation:

Simplify the expression.

− 13.11

Answer:

-13.11

Step-by-step explanation:

Remember: Please Excuse My Dear Aunt Sally (PEMDAS)

You use the parentheses first, so it is 18.03-3*(20.76)÷2

So then, you see there are no exponents, so you multiply and divide from left to right. So, 18.03-62.28÷2. Then you divide: 18.03-31.14

Then, you subtract from left to right, which gives you: -13.11

Given the following expression.

2 1/4 - (-3 2/5)
A. Rewrite the expression using addition.

B. Evaluate the expression.

Answers

In order to rewrite the expression using addition, you would change all the subtraction signs and make the second terms negative. This means that your new expression is 2 + -2 1/4 + 3 2/5. If the number is already negative, the second negative sign would make it positive. Once you've got Part A done, do 2 + -2 1/4 which would give you -1/4. Then you add -1/4 and 3 2/5 by finding common denominators, 20. -5/20 + 3 8/20 would give you 3 3/20 as your final evaluated answer.

–7.5 • (–2¾) and explain how you got the answer

Answers

Answer:

20.625

Step-by-step explanation:

I turned 3/4 into a decimal which would be .75 and then multiplyed -7.5 times -2.75 and then when you multiply 2 negatives you get a positive and then 2.75 times 7.5 is 20.625

1. Negative • Negative = Positive

-7.5 • (-2 3/4) = Positive

2. Turn (-2 3/4) into an improper fraction: (- 11/4) to multiply:

-7.5 • (- 11/4) = 20.625

EXTRA: “If you want, you can turn -7.5 into a fraction too if it helps you better!”
