5.1y + 21.3 = -0.3y - 24.6

get the equation to one side and have so it y is positive

5.4y + 45.9= 0

Then subtract 45.9 to the 0 so it's like this

5.4y = -45.9

then divide -45.9/5.4

answer y= -8.5

Answer: y = -8.5

<u>Explanation:</u>

 5.1y + 21.3 = -0.3y - 24.6

<u>+0.3y          </u>   <u>+0.3y           </u>

5.4y + 21.3 =           -24.6

<u>           -21.3 </u>    <u>         -21.3 </u>

5.4y           =           -45.9

<u>÷5.4          </u>     <u>          ÷5.4  </u>

I own a large truck, and my neighbor owns four small trucks that are all identical. My truck can carry a load of at least $600$
erastova [34]

Answer:

  there is no greatest load

Step-by-step explanation:

Let x and y represent the load capacities of my truck and my neighbor's truck, respectively. We are given two relations:

  x ≥ y +600 . . . . . my truck can carry at least 600 pounds more

  x ≤ (1/3)(4y) . . . . . my truck carries no more than all 4 of hers

Combining these two inequalities, we have ...

  4/3y ≥ x ≥ y +600

  1/3y ≥ 600 . . . . . . . subtract y

  y ≥ 1800 . . . . . . . . multiply by 3

My truck's capacity is greater than 1800 +600 = 2400 pounds. This is a lower limit. The question asks for an <em>upper limit</em>. The given conditions do not place any upper limit on truck capacity.
