X-y=1
x+y=3
You see the y's can cancel out. So add it together and you have:
2x=4
x=2
Now that you have x, plug it in to one of the equations to find y.
I will plug it into the first one.
(2)-y=1
-y=-1
y=1
Answer:
The answer is 43% or 0.43
Step-by-step explanation:
Given:
Probability that person selected aged 35years or older is a smoker = 17.5%
Probability that person selected aged 35years or older is a female comma =25.5%
Solution:
a) Probability (35yrs or older is a smoker) + probability (35years or older is a female comma)
= 17.5% + 25.5%
= 43% 0r 0.43
b) No, it would not be unusual because it is by chance, it may and it may not.
Answer:
the candy is $1.60 a pound
Step-by-step explanation:
8/5=1.60
The end of his round on Saturday was a -5, and the end of his round on Sunday was a 0.
Remark
The slope intercept form is
y = mx + b
Note that the y has 1 as its coefficient and b is related to the 11 (which is neither an x or y term)
Solution
Subtract 2x from both sides.
2x - 2x - 5y = 11 - 2x Combine like terms
-5y = 11 - 2x Divide by - 5
-5y/-5 = 11/-5 - 2x/-5 Do the division
y = -11/5 + 2x / 5 Answer
Discussion
This is not the only answer
It could be
y = 0.4x - 2.2
