Weegy: I need to pass you to another expert

User: 10. Write as a mathematical expression using parenthesis and brackets. Then evaluate. Subtract 4 from 12. Divide this difference by 2. Multiply this quotient by 4.

-4b(5a – 2b ) + 4(-3ab – 5b^2)

= (-20ab + 8b^2) + (-12ab - 20b^2)

= -32ab - 12b^2
8
Subtract 4 from 12: 12 - 4 = 8;
Divide this difference by 2: 8 ÷ 2 = 4;
Multiply this quotient by 4: 4 * 4 = 16

(12 - 4)/2 * 4

= 8/2 * 4;

= 4 * 4

= 16

4x + 18 = 10 User: 12x – 17 = -41
Weegy: 12x-17=-41 (add 17 to both sides), (More)
Question
Updated 12/28/2018 10:22:07 AM
4x + 18 = 10
4x = 10 - 18
4x = -8
x = -8/4
x = -2
12x – 17 = -41
12x = -41 + 17
12x = -24
x = -24/12
x = -2
12x 17= 41
Step 1: Add +17 to both sides.
12x 17+17= 41+17
12x= 24
Step 2: Divide both sides by 12.
12x12= 24
12x= 2
x= 2
Simplify the following expressions using PEMDAS 6 + 3 x 42 – 7 Please show steps with answer.
Question

6 + 3 x 42 – 7;

6 + 126 - 7;

132 - 7 = 125
6 + 3 x 42 – 7 = 125

Since there's only three operation in that expression and if we need to simplify that through using PEMDAS rule then first we have to multiply the numbers with multiplication operation, follows by addition then subtraction and we'll arrive to a correct answer.

PLEASE USE THE P.E.M.D.A.S TO SIMPLIFY THIS PROBLEM: 6 + 3 x 42 – 7
Weegy: 6 + 3 x 42 – 7; = 6 + 126 -7; = 125 (More)

Simplify the following expression using PEMDAS 6 + 3 x 42 – 7 PLEASE SHOW THE DIFFERENTS STEPT
Weegy: 6 + 3 x 42 – 7 a. 3 x 42 first = 126, so it would now be 6 + 1266 -7 b. 6 + 126 = 132, so it would now be 132 - 7 c. finally, 132 - 7 = 125 User: Simplify the following expression using PEMDAS 3 + 4[(8 ÷ 2) + 3]PLEASE SHOW THE DIFFERENTS STEPT Weegy: 3 + 4[(8 ÷ 2) + 3] a. (8 ÷ 2) = 4 b. [4 + 3] = 7 c. 3 + 4 + 7 = 14 User: Simplify the following expression using PEMDAS (6÷ 3) + 4(6÷2)2 PLEASE SHOW THE DIFFERENTS STEPT Weegy: (6÷ 3) + 4(6÷2)2 a. (6÷ 3) = 2 amd (6÷2) = 3, so now it would be 2 + 4 x 3 x 2 b. 4 x 3 = 12 c. 12 x 2 = 24 d. 2 + 24 = 26 (More)
Question

3 + 4[(8 ÷ 2) + 3];

3 + 4[4 + 3];

3 + 4[7];

3 + 28 = 31
Simplify: 4(3 – x) – 3(-5 – 12x)
Question
Updated 12/29/2018 8:50:18 PM
4(3 – x) – 3(-5 – 12x)
= 12 - 4x + 15 + 36x
= 32x + 27
