Leah is training for a bike race she start by biking 8 miles during every training session each week she plans to increase the distance of her training session by 3/4 mile W the number of weeks write an expression to show the distance Leah bikes in a training session after W weeks

8 + 3/4W

Step-by-step explanation:

From the question, we are informed that Leah is training for a bike race she start by biking 8 miles during every training session and that each week she plans to increase the distance of her training session by 3/4 mile W the number of weeks.

The expression to show the distance Leah bikes in a training session after W weeks will be:

= 8 + 3/4W

For example, after 4 weeks, the distance biked will be:

= 8 + 3/4W

= 8 + (3/4 × 4)

= 8 + 3

= 11 miles

we can set up an equation to find the girls' ages. the equation is         28=0.5x-5+x. (comment if you need me to explain how i got this equation.) so, you add x and 0.5x to get 1.5x and add 5 to each side. your new equation is 33=1.5x. now divide both sides of the equation by 1.5 to get 22=x. because x is mary's age, to find jasmine's age we subtract mary's age from 28. we find that mary is 22 years old and jasmine is 6 years old.
