A mom is 7 times older than her daughter. In five years, she will be 4 times older than her daughter. Find there ages now. I am timed so asap please

Mom === 10.25

Daughter === 3.25

Step-by-step explanation:

Let’s the mom age be 7+x and the daughters age be x. Put it in a linear equation 7+x=5(4+x).

open the bracket which will give you 7+x=20+5x.

collect like terms which will give you 5x-x=20–7 and you will get 4x=13 where x is 3.25 the mom is 10.25 and the daughters age is 3.25

mom 10.25

kid 3.25

Step-by-step explanation:multiplication

ab will be equal to

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
