2(5c+ 2) - 2c = 3(2c + 3) + 7
Mademuasel [1]

Answer:

c = 6

Step-by-step explanation:

Step 1: Write equation

2(5c + 2) - 2c = 3(2c + 3) + 7

Step 2: Solve for <em>c</em>

  1. Distribute: 10c + 4 - 2c = 6c + 9 + 7
  2. Combine like terms: 8c + 4 = 6c + 16
  3. Subtract 6c on both sides: 2c + 4 = 16
  4. Subtract 4 on both sides: 2c = 12
  5. Divide both sides by 2: c = 6

  3×10^4

The desired factor is found by calculating the ratio of the two numbers:

  k = (9×10^2)/(3×10^-2) = (9/3)×10^(2 -(-2)) = 3×10^4

The first number is 3×10^4 = 30,000 times as much as the second number.

Leo's age is three times Stan’s age. In five years, Leo will be twice as old as Stan. How old is each now?
aleksandr82 [10.1K]

Answer:


Step-by-step explanation:

L=3S

In 5 years,

L+5=2(S+5)

L+5=2S+10

L=2S+5

 Substituting from above,

3S=2S+5

S=5

So then,

L=3(5)

L=15
