Answer:
solution set is (x,y) = (7,6)
Step-by-step explanation:
solving by substitution method
2x +y=20--------------1
6x-5y=12---------------2
from equation 1, solve for y
2x+y=20
y= 20-2x------equation 3
adding value of y in equation 2
6x-5y=12
6x-5(20-2x)=12
6x-100+10x=12
16x= 12+100
16x= 112
x= 112/16
x=7
adding value of x in equation 3
y= 20-2x
y= 20- 2(7)
y=20-14
y=6
so solution set (x,y) = (7,6)

Hey there,
Given the question it shows that Ryann swam 1/4 of 14 miles that he was supposed to swim.
In words of is another way to say 1/4 * 14...
This expressed as a mixed number would be...
Of the 14 miles that Ryann was supposed to swim he swam 3 1/2 miles.
Hope I helped,

Answer:
C. $0 because $25.36 and -$25.36 are additive inverses.
Step-by-step explanation:
Additive inverses means 2 numbers that are the complete opposite.
When additive inverses are added together, their sum is 0.
Example: 1 and -1.
They're both additive inverses because they're on the opposite sides on the number line, if -1 had to be a positive, it wouldn't be an inverse.
<u>Given:</u>
- Before the deposit, her bank account balance is -25.36.
- She has deposited $25.36 into her bank account.
<u>Solve:</u>
Let's add both -25.36 and 25.36.
-25.36 + 25.36 = 0.
C. is the correct choice, and the reasoning is valid.
