Answer:
x=5/4, y=7/4
Step-by-step explanation:
This is a similar triangles problem.
The first triangle (the smaller one) has the lengths 5, 8 and 7.
The second triangle (the lager one) has the lengths 5+x, 10, and 7+y
Let's first solve for x
In any similar triangles problem, you can make two ratios (all the ratios of the sides are the same)
since we don't know the measures for x and y first, we can use the ratio of the parallel lines (the bases) as the first ratio (8/10)
For the second ratio, it's smaller/bigger, so it'll be 5/(x+5)
here's the proportion
5/(x+5)=8/10
But before we multiply, we can simplify 8/10 to 4/5
so
5/(x+5)=4/5
Cross multiply
25=4x+20
5=4x
5/4=x
For y, we can do a similar process
We can use 8/10 or 4/5 again
and the ratio of the sides for y will be 7/(y+7)
7/(y+7)=4/5
35=4y+28
7=4y
7/4=y

Answer:
d. y = 0.1x+ 200
Step-by-step explanation:
His weekly salary is 200, that is the y intercept
He makes 10% (.10 in decimal form) of his weekly sales, that is the slope
y= mx+b
y = .1x+200

The cost of one bag of Tabitha Tidbits costs $7.00 and cost of one bag of Figaro Flakes costs $5.50
Step-by-step explanation:
Let,
Cost of one bag of Tabitha Tidbits = x
Cost of one bag of Figaro Flakes = y
According to given statement;
3x+4y=43.00 Eqn 1
3x+6y=54.00 Eqn 2
Subtracting Eqn 1 from Eqn 2
Dividing both sides by 2
Putting y=5.50 in Eqn 1;
Dividing both sides by 3
The cost of one bag of Tabitha Tidbits costs $7.00 and cost of one bag of Figaro Flakes costs $5.50
