2 answers:
Answer:
Infinitely many solutions
Step-by-step explanation:
We are given that
...(1)
....(2)
We have to find that 0=0 what indicates about the solution of the system
Equation (1) divided by 2 and equation (2) divided by-5 then we get
.....(3)
...(4)
Adding equation (3) and (4) then we get
We know that
When we get these type of condition in which 0=0
Then , the solution of the system are infinite.
Hence, 0=0 indicates that solution of the system are infinite.

Answer:
Step-by-step explanation:
Complete question
<u>On Thursday, r centimeters of rain fell on Deborah's garden. On Saturday, 15% more rain fell on the garden. </u>
<u>The expression r+0.15r describes the number of centimeters of rain Deborah's garden got on Saturday. We can also use the expression 1.15r to represent the same quantity. </u>
<u>Match each amount in the situation with the expression that represents it.</u>
<u />
Since we have given that
Let amount of rainfall on Deborah's garden on Thursday be 'r'.
According to question, 15% more rainfall on the garden on Saturday.
So, Amount of rainfall on Saturday would be
Hence, Deborah got 1.15r amount of rainfall on Saturday.
