The correct solution is x=5,y=1
Ste<u>p-by-step explanation:</u>
Given the set of equations
4x-9y=11(1)
10x-9y=41(2)
we have to determine the values of x and y
solve this using elimination method
4x-9y=11(1)
10x-9y=41(2)
(2)-(1)
10x-4x-9y-(-9y)=41-11
10x-4x-0=30
6x=30
x=30/6
=5
substitute y in (1)
x=5
y=1
Answer:
Step-by-step explanation:
1) Add all the values.
= 10 + 35 + 30
= 75
2) 75 will be the denominator and the one required will be the numerator.
Since there are 30 peanut butter cookies, the probability is .
3) Simplify the fraction if necessary.
Divide both sides by 15.

Hi there!
Keep in mind that even though there is a number outside of the parentheses, you only use the distributive property of multiplication when the numbers inside the quantity are not being multiplied or divided by each other.
That means we need to multiply what is in the parentheses before multiplying what lays outside of them.
675 * 0.0025 = 1.6975
Now multiply 1.6975 times 24.17.
1.6975 * 24.17 = 41.028575.
And there you go!
Round, if necessary.
