10 1/2 that is the your right I am a ten year old boy I know this wow you cant do it I believe in you you can do it
Hello,
To solve this system of equations, we want to add or subtract the equations so that either x or y cancels out.
We can multiply the first equation by -2, so that 5y will become -10y, and then add the equation with the second so -10y and 10y will cancel out.
Multiplying the first equation by -2, we get:
-4x - 10y = -30
Add this to the second equation and we get:
x = 5
So, we have x = 5. However, we should plug it into both equations to solve for y and make sure both answers check out.
Doing this for the first equation, we have:
2(5) + 5y = 15
10 + 5y = 15
Subtract 10 from both sides to get:
5y = 5
Divide by 5 on both sides to get:
y = 1
We will now see if x = 5 and y = 1 works for the second equation.
5x + 10y = 35
5(5) + 10(1) = 35
35 = 35, checks out
So, x = 5 and y = 1.
Option choice B is correct.
Hope this helps!

Got it right :)
Answer: a) 0.29, b) 0.9
Step-by-step explanation:
Since we have given that
Probability that a person chosen did not complete high school = 0.10
Probability that the person has a high school diploma but no further education = 0.27
Probability that the person has at least a bachelor's degree = 0.34
So, Probability that a randomly chosen young adult has some education beyond high school but does not have a bachelor's degree is given by
=1- P(a person chosen did not complete high school)-P(the person has a high school diploma but no further education)-P(the person has at least a bachelor's degree)
Probability that a randomly chosen young adult has at least a high school education is given by
= 1- P(a person chosen did not complete high school)
Hence, a) 0.29, b) 0.9
3/4 for the fraction less than 1 since 3/4= 0.75.
For the fraction greater than 1 use 4/3 sicne4/3 = 1.333333....
Hope this helps!
