Answer:
Kyle saves 40 percent
$50 is 100% of what he had
$20 would be 40%
50= 100
40= 80
30= 60
20= 40
10= 20
do what u will with that info I'm bad at wording things
Answer:
x = .87, or when approximated to a fraction, 27/31
y = -3.67, or when approximated to a fraction, -1287/350
Step-by-step explanation:
Lets start by rewriting out our equations
2x + 7y = -24
18x + y = 12
Lets solve for a y value; the second equation is easiest, as the y value has no coefficient (the number that is multiplied times a variable). To do this, lets move the 18x to the other side. Now our two equations look like:
2x + 7y = -24
y = -18x + 12
Next, lets plus the second equation into the first equation in regards to y.
2x + 7(-18x + 12) = -24
Now, lets solve!
2x -126x + 84 = -24
Then, combine your terms!
-124x = -108
Divide by (-124)!
x = -108/-124
x = 27/31
Now that we know x, lets plug this back in to the first equation to find y!
2(27/31) + 7y = -24
1.74 + 7y = -24
7y = -25.74
y = -3.67, or when approximated to a fraction, -1287/350

Answer: 24 in³
Step-by-step explanation:
You know that the dimensions of the box are:
3 inches.
4 inches.
2 inches.
As each face of the cardboard box is a rectangle, you can conclude that it has the form of a rectangular prism.
Therefore, to calculate the volume of the box, you must multiply the dimensions given in the problem.
Therefore, you obtain that the volume of the box is:
