A carpenter uses two different types of paint in his work, X-Brand and Y-Brand (represented by the x and y variables respectively in the system of equations below).

2x+5y=6
−x+2y=−3
Answers
Answer
$3
Step-by-step explanation:
To find the x value, you want to cancel out the y terms in the equations. To do so, multiply (2x+5y=6) by 2, and (-x+2y=-3) by -5. This gives you
4x+10y=12
5x-10y=15
You can then cancel out the y terms and add the other terms from the 2 equations together to make
9x=27
You then divide 27 by 9 to get 3 as the value for x.

Answer:
15) x = 10.2
16) x = 22.7 and y = 44.6
Step-by-step explanation:
15) tan 52° = 13/x
x = 13/tan 52°
16) sin 90°/50 = sin 27°/x
x = 50(sin 27°)
sin 90°/50 = sin 63°/y
y = 50(sin 63°)

Answer:
15%
Step-by-step explanation:
not that hard just make it a decimal then at the point go back twice and there its 15%
Answer:
15%
Step-by-step explanation:
Since 100 isn't the denominator we need to make it a denominator.
3/20 x 1/5 = 3/100 we need to do the same to the denominator because whatever we do to the denominator has to do with the numerator 3 x 5 = 15,
15/100 means 15%!

Explain what median is and how to solve for it
Answers
Answer: See below
Step-by-step explanation:
Median is the value that separates the higher data and lower data. In simple terms, it is the "middle" value of the whole set of data. There are two different ways to solve for the median.
1. If the data set has an odd number of values, line the values up in increasing order. Then the value or number that lies in the middle will be the median.
For example, if we are given a data set {1, 3, 4, 2, 5}. First, we line them up by increasing order, which becomes {1, 2, 3, 4, 5}. Since it is an odd number set, we can directly get the median which is 3.2. If the data set has an even number of values, line the values up in increasing order. Then there will be two number that lies in the "middle" together. We add them up and divide them by 2. The average of the two numbers will be the median of the set.
For example, if we are given a data set {2, 6, 4, 10, 8, 12}. First, we line them up by increasing order, which becomes {2, 4, 6, 8, 10, 12}. Since it is an even number set, we get our median from the two numbers in the middle, which are {6, 8}. We add them together to get 14 and then divide by 2 which is 7. So the median will be 7.Hope this helps!! :)

h = 7 in
LA = 42π in²
SA = 60π in²
Step-by-step explanation:
Use the appropriate formula with the numbers you know, and solve for the number you need to know.
V = πr²h
h = V/(πr²) = (63π in³)/(π(3 in)²)
h = 7 in
__
LA = 2πrh
LA = 2π(3 in)(7 in)
LA = 42π in²
__
SA = 2πr(r +h)
SA = 2π(3 in)(3 in +7 in)
SA = 60π in²
