Answer:
18 and 52
Step-by-step explanation:
x + Y = 70
X - Y= 34 find the value of X interms of Y to find the answer:
X - Y= 34
X = 34 +Y
x + Y = 70
(34 + Y ) + Y = 70
34 + Y +Y = 70
2Y =70-34
2Y/2=36/2
Y = 18
x + 18 = 70
x=70 - 18
x= 52
check:
18 + 52= 70
52 - 18= 34
750/x=25/100
750x100=75,000
75,000/25= 3,000
75,000+3,000= 78,000
Answer: 5/4
Explanation:
We have the same denominator so we can just add the numerator.
= 6/8 + 4/8
=10/8
10/8 can be simplified
=5/4
There is no solution. No matter what numbers are used, both systems will never be satisfied.
Answer: 80 dollars
Step-by-step explanation:
You can find a percentage with one of two ways.
For hundreds like this, oftentimes it's quicker and more simple to think of it as just 100. The proportion from 100 to 500 is just 5. 16% of 100 is 16. So, multiply 16 * 5. You would get 80.
The second method is you can use 0.16 * 500. It's the more conventional method, and you get 80, like the last method.
