User: Score: The product of 8 and the sum of 4 and a number is 112. What is the number? Which equation could be used to solve for the number? 8 + 4n = 112 8 x 4 + n = 112 8(4 + n) = 112

Weegy: The product of 8 and the sum of 4 and a number is 112. The equation that could be used to solve for the number is: 8(4+n)=112. To solve: 8(4+n)=112; 32+8n=112; 8n=112-32; 8n=80; n=80/8; n=10

User: Ralph is 3 times as old as Sara. In 6 years, Ralph will be only twice as old as Sara will be then. Find Ralph's age now. Which of the following equations could be used to solve the problem? 3x+ 2x x+ 6 = 2(3x+ 6) 3x+ 6 = 2(x+ 6) 3x+ 6 = 2x+ 6

Weegy: c.3x + 6 = 2(x + 6). Ralph is 18 now, Sara 6 now.

User: 3x - 5x + 8x + x = 42 6 7 8

Weegy: 3x - 5x + 8x + x = 42

-2x + 9x = 42

7x = 42

x = 6

User: What is the percent of decrease on an item that went from \$25 to \$20? 20% 25% 80%

Weegy: 20 / 25 = 0.8 So 20 is 80% of 25. Therefore the percentage decrease it (100 - 80) percent, i.e. 20%.

User: Solve for n. -53 + n = -28 -35 -25 25 35

Weegy: -53 + n = -28, add 53 to both sides, n = 25. The answer is 25.

If 5 liters of a solution are 20% acid, the amount of solution that is acid is: 5*20% = 5*0.2 = 1 liter.

3(x + 5) - 2(x + 2) = 20
3x + 15 - 2x - 4 = 20
x + 11 = 20
x = 20 - 11
x = 9

3x + 1 = 3x + 2 has no solution.
3x + 1 = 3x + 2
3x - 3x = 2 - 1
0 = 1 which is a false statement.
There is no solution for the equation 3x + 1 = 3x + 2
