Please help with 6 and 7
Ilya [14]

Answer:

6. The number is -5

7. The two numbers are 10 and 11

Step-by-step explanation:

Question six can be re-worded to create the following expression:

-2=\frac{4x+10}{5}

Solve for x to find the number:

-2=\frac{4x+10}{5}\\-10=4x+10\\-20=4x\\\frac{-20}{4} = x\\-5 = x

Question seven can be solved by first listing the constraints (assuming x is smaller than y):

  1. x and y are less than 20
  2. x + 1 = y
  3. 3x - 8 = 2y

To get the numbers, we can create a system of linear equations. First, solve for y in each expression:

y = x+1

2y = 3x-8\\y = \frac{3}{2}x - 4

Solve for x:

x+ 1 = \frac{3}{2}x - 4\\x + 5 = \frac{3}{2}x\\5 = \frac{3}{2}x - x\\5 = \frac{1}{2}x\\10 = x

Solve for y:

y = x + 1\\y = 10 + 1\\y= 11

Carlos and Lily want to know the combined amount of money they made last week. They both made $12 per hour, but Carlos also made
steposvetlana [31]

Answer:

  • Lily is right

Step-by-step explanation:

<u>Carlos made:</u>

  • 12C + 35

<u>Lily made:</u>

  • 12L

<u>Together they made:</u>

  • 12C + 35 + 12L = 12(C + L) + 35

Lily is right. We don't know what 120 means in Carlos's equation, he should put 12L for Lily.
