Answer:

there are 20 tons before the bridge reaches its limit because you get 80 tons in total weight

Step-by-step explanation:

you would first multiply 80,000 pounds by 2 which gives you 160,000 pounds then you divide that by 2,000 because a ton is equal to 2,000 pounds

riadik2000 [5.3K]

Answer:

The cost for 1 chair is $2.75 and the cost for 1 table is $8.75

Step-by-step explanation:

Use the elimination method of linear equations to find your answer.

Our equations for this problem are:

3c+5t=52 and 9c+7t=86

1. Multiply the entire first equation by -3.

-3(3c+5t=52)

2. Simplify the equation from above:

-9c-15t=-156

3. Stack the two equations on top of each other and add/subtract:

-9c-15t=-156

9c+7t=86

4. You should be left with -8t=-70. Simplify this to find the value of t:

t=8.75

5. Plug the value of t into any of the original equations and solve for c.

3c+5(8.75)=52

6. Simplify the equation above:

3c+43.75=52

7. Subtract 43.75 from both sides of the equation:

3c=8.25

8. Divide both sides by 3 to get your c value:

c=2.75

2e = 4e - 16

*subtract 4e from both sides

-2e = -16

*divide both sides by -2

<u><em>e = 8</em></u>
