Answer:
$1.36
Step-by-step explanation:
First, add together the prices of all the clothes:
18.28 + 42.39 + 12.97
= 73.64
Then, subtract this from 75:
75 - 73.64
= 1.36
So, he will have $1.36 left after buying the clothes
Answer:
Length = 18 in
Width = 15 in
Step-by-step explanation:
We have that the area of a rectangle is:
A = L * W
but L = 1.2 * W
A = 1.2 * (W ^ 2)
1.2 * (W ^ 2) = 270
(W ^ 2) = 270 / 1.2
W ^ 2 = 225
Therefore, W is equal to:
W = 225 ^ (1/2)
W = +/- 15, but only +15 makes sense
W = 15
Now for L:
L = 1.2 * 15
L = 18
A = 15 * 18 = 270 in ^ 2
No . . . while the difference represents the absolute magnitude between two numbers . . . for example . . .
<em>The difference between 5 and 2 is . . . 3</em>
<em>The difference between 6.4 and 9.5 is . . . 3.1</em>
. . . there is still the chance that the difference may be zero . . . in which case the difference is neither positive nor negative
. . . so in short . . . the answer is . . . <u><em>NO</em></u>
Answer:
A number is positive if it is greater than or equal to zero. A number is negative if it is less than or equal to zero.
One way is to move the 4 to other side so it would be x = 13 - 4 and that's x = 9
