Answer:
8x + 2y
Step-by-step explanation:
You need to use distributive property.
5(x + y)
5 · x = 5x
5 · y = 5y
3(x - y)
3 · x = 3x
3 · -y = -3y (don't forget the sign)
So,
5x + 5y + 3x - 3y
Arrange them,
5x + 3x + 5y - 3y
Simplify,
5x + 3x = 8x
5y - 3y = 2y
So,
8x + 2y
Answer:
y = (3/2)x + 11
Step-by-step explanation:
We can start from the point slope form of a linear function:
(y-y1)=m(x-x1)
The slope m can be determined from the points given as m = (y2-y1)/(x2-x1)=(8-2)/(-2-(-6))=6/4=3/2
Then use either of the given points as x1, y1 to complete the equation (I picked the point (-6,2):
y-2=(3/2)(x+6)
You can rearrange this to:
y = (3/2)x + 11
Answer:
130g
Step-by-step explanation:
There are several ways to answer this question and I will use this approach. Since Johnny reads at a ratio of 7:3 it can be stated that for every 10 pages in a book containing 500 pages Johnny will read 7 of those pages. There are 50 groups of 10 in a 500-page book (50 x 10). Take the ration 7:3 times 50 and use the distributive property: 7:3(50) = (7 x 50):(3 x 50) = 350:150. Based on this Johnny has read 350 pages and has 150 pages remaining.
