Answer:

the number is 49

Step-by-step explanation:

first, write an equation based on the words

4 increased by= 4+

three fifths of a number = 3/5 * n

is 49: =49

now, put it together: 4 + 3/5*n=49

Now, solve

4 + 3/5*n=49

4-4=0   49-4= 45

3/5*n=45

3/5*n / 3/5= n    45/ 3/5= 75

n=75

hope this helps:)

What is the solution to this equation?<br> 9x - 4(x - 2) = x + 20
ioda

9x - 4(x - 2) =x + 20

We move all terms to the left:

  • 9x -4(x - 2) - (x + 20) = 0

Multiply

  • 9x - 4x -(x + 20) + 8 = 0

We get rid of the parentheses.

  • 9x - 4x - x - 20 + 8 = 0

We add all the numbers and all the variables.

  • 4x - 12 = 0

We move all terms containing x to the left hand side, all other terms to the right hand side

  • 4x=12
  • x = 12/4
  • x = 3
