Answer:

The required list is: 0 car and 37 truck; 8 car and 30 truck; 16 car and 23 truck; 24 car and 16 truck; 32 car and 9 truck;

Step-by-step explanation:

Consider the provided information.

A toll collector on a highway receives ​$8 for trucks and ​$7 for cars, at the end she collected ​$296.

Let t represents the number of trucks and c represents the number of cars pass through highway.

8t+7c=296

8t=296-7c

t=37-\frac{7c}{8}

The number of trucks should be natural number.

Substitute c=0 in t=37-\frac{7c}{8}

t=37-\frac{7(0)}{8}

t=37

Substitute c=8 in t=37-\frac{7c}{8}

t=37-\frac{7(8)}{8}

t=37-7

t=30

Substitute c=16 in t=37-\frac{7c}{8}

t=37-\frac{7(16)}{8}

t=37-14

t=23

Substitute c=24 in t=37-\frac{7c}{8}

t=37-\frac{7(24)}{8}

t=37-21

t=16

Substitute c=32 in t=37-\frac{7c}{8}

t=37-\frac{7(32)}{8}

t=37-28

t=9

Hence, the required list is: 0 car and 37 truck; 8 car and 30 truck; 16 car and 23 truck; 24 car and 16 truck; 32 car and 9 truck;

Need help with Geometry homework.
solmaris [256]

Answer:

SU = 22

Step-by-step explanation:

SR = RU

4x - 1 = x + 8

3x - 1 = 8

3x = 9

x = 3

SR =  4(3) - 1 = 11

RU =  3 + 8 = 11

SU = 11 + 11 = 22

How do i get the solution to graph 2x+3y=12
Pavel [41]
2x + 3y = 12

I am going to put this in y = mx + b form, where m is ur slope and b is ur y intercept.
2x + 3y = 12
3y = -2x + 12
y = -2/3x + 4......slope is -2/3 and y int is (0,4)

x int can be found by subbing in 0 for y and solving for x
2x + 3y = 12
2x + 3(0) = 12
2x = 12
x = 6.....so x int is (6,0)

start at y int (0,4).....and since the slope is -2/3, come down 2 spaces, and to the right 3 spaces, then down 2 spaces, to the right 3 spaces....keep doing that and u should cross the x axis at (6,0)

Two garden plots are to have the same area. One is square and one is rectangular. The rectangular plot is 4 meters wide and 16 m
AlexFokin [52]

side = 8 m

the area of the rectangle = length × width = 16 × 4 = 64 m²

the area of the square = s² ( where s is the length of a side ), hence

s² = 64 ( since areas are equal )

take the square root of both sides

s = √64 = 8 m
