In 45 years will be 4 times older how old is she now

Answer and Step-by-step explanation:

The key for this has a current age and a future age. Sometimes these problems have more than one person or has a past age.

       current age     future age

        x                    x+45

The future age is 4 times current age

x+45 = 4x

   45 = 3x

   15 = x

She is currently 15. 45 years from now she will be 60.

60 is 4 times her current age. So right now, she is 15.

11yrs (6months)

Step-by-step explanation:

11.5×4=45

Since .5 in years is 6 months

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
