Answer:
11
Step-by-step explanation:
The diagonals in a rectangle are the same length.
WY = XZ
6x -7 = 3x +2
3x -7 = 2 . . . . . . subtract 3x
3x +2 = 11 . . . . . .add 9 to match the expression for XZ
The length of each diagonal is 11 units.
_____
Note that we took a little shortcut to the solution. We don't actually need to know the value of x. We only need to know the value of one of the expressions for diagonal length. The expression containing "3x" is the most convenient to determine.
Answer:
C
Step-by-step explanation:
We are dining the value that is $92 fewer or less than she did on the 7th. On the 7th, she had $48. Subtracting $92, we get $48 - $98 = -$44 = money she had on the 14th. Therefore, the answer is C.
Well, "m" represent $32 she spends a month and "t" be the $0.75 for each minute will be.
First, since the bill is for one month, we can place "m" by itself with no add-ons to it since it's been stated only a month is going by and it stays $32. However, depending of "t" the price can change without the original monthly plan changing, so we write it like m + (t . x). "x" represent every minute spent over the time limit, so it's "t" times "x" since whatever "t" is is determined by "x". If "x" is 0, then "t" is 0 since nothing is added and it'd remain $32. If say "x" was 10 however, that would mean 10 minutes have gone over the limit, so 0.75 x 10 would be $7.50 + $32 making it $39.50.
Your answer is m + (t . x)
Note: "m" and "t" can be different if you choose.
You do 4/5+1/5=4/5 and then you do 5/5-4/5=1/5 of a meter is needed.
