$72
Given:
Abbie spent ⁵/₈ of her money and saved the rest.
She spent $45.
Question:
How much money did she have at first?
The Process:
The meaning of "Abbie spent ⁵/₈ of her money" is that she has spent 5 of the 8 parts of the money she had at first.
Let us make a pattern of 8 units for the amount of money that Abbie had at first.
Since Abbie spent ⁵/₈ of her money, then we create a pattern of 5 units containing $9 each. Recall that
From the pattern above, we can see that
Let us calculate how much money Abbie had at first.
Thus, the money Abbie had at first is $72.
The complete pattern of Abbie's initial money is as follows:
- - - - - - - - - -
Quick Steps:
Let M as Abbie's initial money.
Both sides are multiplied by ⁸/₅ so that M is the subject alone on the left side.
We crossed out 5 and 45.
Thus, the money Abbie had at first is $72.

The GCF of 135, 225, and 270 is 45.
The GCF (Greatest Common Factor) is the largest number that divides evenly into two or more numbers. To find the GCF of 135, 225, and 270, we need to find the common factors of the three numbers and choose the largest one.
The factors of 135 are: 1, 3, 5, 9, 15, 27, 45, 135.
The factors of 225 are: 1, 3, 5, 9, 15, 25, 45, 75, 225.
The factors of 270 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270.
The common factors of 135, 225, and 270 are: 1, 3, 5, 9, 15, 45.
The largest common factor is 45. So, the GCF of 135, 225, and 270 is 45.

X+Y=6
X-Y=10
Step-by-step explanation:
x + y = 6 ...................equation 1
x - y = 10 ..................equation 2
Solving equation 1 and 2
x + y = 6
x -y =10
2x = 16
x = 16 /2
Therefore x = 8
Now
putting x = 8 in equation 1
8 + y = 6
y = 6 -8
y = -2
hope it was helpful :)
Answer:
x=8 and y= -2
Step-by-step explanation:
x+y=6
x-y=10 + ( add them together)
-----------------
2x=16 ( substitute/ plug x back in )
x=8
8+y=6
8-y=10
y=-2
