\\ \sf\longmapsto -4d-5=-1

  • Cancel - from both sides

\\ \sf\longmapsto -(4d+5)=-(1)

\\ \sf\longmapsto 4d+5=1

\\ \sf\longmapsto 4d=1-5

\\ \sf\longmapsto 4d=-4

\\ \sf\longmapsto d=\dfrac{-4}{4}

\\ \sf\longmapsto d=-1

Jack wants to fill a rectangular box with sand. The length of the sand box is 3 feet, width is 6 inches, and height is 2.4 inche
Aleksandr-060686 [28]
Jack would need to buy 2 bags of sand.
To find the answer you first have to find the volume of the rectangular box which can be found using the formula length times width times height (remember that the numbers have to have the same unit so it would look like 3 times .5 times .2 if you convert them all the feet). the volume of the box is equal to .3
Then you could set the volume of the box equal to .15x to find how many boxes he would need. The formula would be .15x=.3
Divide by .15 to get x alone and you get 2 for the answer.

elena-14-01-66 [18.8K]
Well, we can set up these equations like this-
Deborah- 2+3w
Kai- 12+2w
w=number of weeks that pass
Now, we set them equal to each other:
2+3w=12+2w

Solve for w
2-12=2w-3w
-10 = -1w
w = 10
10 weeks. Hope this helped!

PLEASE HELP MEEEEEE PLEASEEEEEEEE!!!!!! IM TIMED
crimeas [40]

Set up an equation to solve.

$8.50x (since it is the rate of change) + $12 (flat fee) = total money earned (or y). In this case, we have the total, amount, and are looking for x. Plug $139.50 into the equation.

$8.50x + $12 = $139.50

Now, solve for x.

$8.50x + $12-12 = $139.50-12  > <em>$8.50x = $127.5</em>

$8.50/8.50x = $127.5/8.50 > <em>x = 15</em>

So, the correct answer is <u>D. Olivia babysat for 15 hours.</u>
