8x + 7y = -15 (1st)
-7x - 9y = -7 (2nd)
multiply (1st) by 7 and (2nd) by 8
56x + 49y = -105 (multiply 7)
-56x - 72y = -56 (multiply 8)
--------------------------------------------add
-23y = -161
y = 7
8x + 7y = -15
8x + 7(7) = -15
8x + 49 = -15
8x = -64
x = -8
answer
x = -8 and y = 7
The answer is A. 6101. I got this by taking 36606 and dividing it by 6. This result in answer A. I hope this helps
Answer:
The survey shows that 20% of the individuals were satisfied with the car.
Step-by-step explanation:
- We are given that 2,300 people were surveyed.
- We are also given that 460 of those individuals would buy that car again.
- We need to find the percentage of individuals that were satisfied with the car.
When we need to find the percentage of a population, we can use the following formula:
We need to identify the part and the whole in this problem.
We are given that 2,300 people are surveyed, so this is the <u>whole</u> portion.
We are also given that 460 were satisfied, so this is the <u>part</u> portion.
Therefore, we can set up our fraction.
Now, let's solve the percentage.

Therefore, of those surveyed, 20% of the individuals were satisfied with the car.
Answer:
<u>Solving it mentally</u> :-
It says 25% × 44. When we have a percent, change it to decimal and solve which would be easy to do it mentally.
25% = 0.25
0.25 × 44 = 11 *Answer is bolded.*
<u>Solving it on paper</u> :-
I have attached a picture of me doing it on paper.
Hope this helps, thank you :) !!
