15 points! will give brainliest! a rental car company offers two rental plans, plan a and plan b, for the same economy size car. for both plans, the total rental cost, ƒ(m) is a function of the number of miles, m, that the car is driven. in addition to a flat fee of $75, plan a offers a rate of $0.20 per mile for an unlimited number of miles. plan b offers a higher mileage rate of $0.35 per mile but does not charge a flat fee for the rental. create a system of linear functions modeling the cost of the car rental plans, a and b, as a function of the miles driven. for how many miles, m, will the rental fee be the same under both plans a and b?

let r = rental cost and m = miles

the rental cost of plan a is $75 plus $0.20 per mile

r=75+0.20m

the rental cost for plan b is $0.35 per mile

r=0.35m

the two plans are the same when

75 +0.20m = 0.35m

75=0.15m

500=m

answer: for each 3 girls there is 2 boys . 3: 2

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
