We need to find an expression which will help Sara calculate the total weight of the truck.

By hypothesis, we know that x represents the number of cans in the truck. And each can weigh 14 ounces, so the total weight of the cans in the truck is 14*x = 14x.

Now in the truck, there's a total of 840 cans and bottles combined. And x is the number of cans. So 840 - x is the number of bottles. And since each bottle's weight is 70 ounces, the total weight of the bottles in the truck is 70*(840-x) = 70*840 - 70*x = 58800 - 70x.

Now to find the total weight, we add the weight of the cans to the weight of the bottle: 14x + 58800 - 70x = 58800-56x.

So the equation to find the total weight of the truck is:

58800-56x, in which x represents the number of cans in the truck.

Hope this helps! :)

Romashka-Z-Leto [24]

Answer:

121 x 59 (Dimensions)

Step-by-step explanation:

6x + 6 = 360

Take away 6 from both sides

6x = 354

Divide both sides by 6

x = 59

The length is 2x + 3 because it says 3 more than double the width (lenght is x). You have 2 widths and 2 lengths. The two widths are both x (2x). The two lengths are both 2x + 3 (4x + 6). 2x + 4x + 6 = 6x + 6.

Now input 59 for x

2(59) + 3 = 121

x = 59

Check Your Answer

121 is just one length and 59 is just one width, so you have to multiply both sides by 2 because you have 2 widths and 2 lengths.

121 x 2 = 242

59 x 2 = 118

242 + 118 = 360

What is the solution of the system? Use substitution.
trasher [3.6K]

Hi

4x-y=5

3x-7=2

We need to solve 3x-7=2 for x

Let's start by adding 7 to both sides

3x-7+7=2+7

3x=9

Now just divide both sides by 3 so we can find the value for x

3x/3=9/3

x=3

Now substitute 3 for x in 4x-y=5

4x-y=5

(4)(3)-y=5

-y+12=5

Now add -12

-y=12-12=5-12

-y=-7

Divide both sides by -1 so we can eliminate the negative sign

-y/-1=-7/-1

y=3

The answer is A
