Semmy [17]

Answer:

B rentals is better deal for journey 432 miles

If she spending same money either company the distance travels in a week is $x=600$ miles

Step-by-step explanation:

Given,

Mr K rentals cars $=\$ 99$ per week and $\$ .11$ for over 100 miles

B rentals car $=\$ 75$ per week and $\$ .15$ for over 150 miles

Let total journey cost of Glenna if she travels 432 miles

For Mr, K rentals is Y

Y=99+.11\times \left ( 432-100\right )

$Y=99+.11\times \left ( 432-100\right )$

$Y=99+36.52$

$Y=\$ 135.52$

For B rental journey cost is Z

$Z=75+.15\left ( 432-150 \right )$

$Z=75+42.3$

$Z=\$ 117.3$

If she spending same money either company

x mile she drive in a week

$Y=Z$

$99+.11\left ( 432-100 \right )x=75+.15\left ( 432-150 \right )x$

$99-75=.15x-.11x$

$24=.04x$

$x=24/.04$

$x=600$

PLEASE HELP ASAP, I NEED A PERFECT SCORE. I'M IN A STRESS AND PANIC MODE BECAUSE I MAY NOT FINISH 9TH GRADE, PLZ HELP ME ANSWER

grandymaker [24]

M(x) = 5x + 4 n(x) = 6x - 9

Part 1 (m + n)(x) = 5x + 4 + 6x - 9
= 11x - 5

Part 2 (m * n)(x) = (5x + 4)(6x - 9) = 30x^2 - 21x - 36

Part 3 m[n(x)] = 5(6x - 9) + 4
= 30x - 45 + 4
= 30x - 41
