Answer:
y = 0.70x- 10.00
Step-by-step explanation:
-- Since one friend gave you 10.00 ,subtractthis from the 13.50 to give you the amount earned by walking the 5 miles
-- 13.5-10.00 = $3.50
-- Since you walked 5 miles, divide by 5 to give you 0.70 per mile earned.
So, an equation that represents the amount of money earned is:
y = 0.70x- 10.00 . This is in slope-intercept form; the slope is $0.70 and represents the amount of money earned per mile and the intercept is $10.00 and represents the initial amount of money that you were given.
You buy 3 shirts and 1 pair of pants for $32. Your friend buys 2 shirts and 3 pairs of pants for $40. How much did each item cost?
First let’s define a shirt as X and pants as Y!
In the first scenario, the equation will be 3X + Y =$32
In the second scenario, the equation will be 2X + 3Y = $40
Now because we have two different variables (X & Y) let’s solve for one of them (Ex: Y) to simplify the equations!
3X + Y= $32—> subtract 3X on both sides of the equation
-3X. - 3X
Net result: Y= 32- 3X
Now we can insert this into the second equation 2X + 3Y = $40 in order to solve for X variable
2X + 3(32-3X) = $40
2X + 96 - 9X = $40 —> simplify the equation
-7X + 96 = $40 —> substrate 96 from both sides
-7X = -56 —> divide both sides by -7
X= 8
Now reinsert 8= X into 3X + Y = $32
3(8) + Y = $32
24+ Y = $32 —> substract 24 from both sides
y = 8
ANSWER: X= 8, Y= 8

Answer:
1. 1/36
2. 9/64
Step-by-step explanation:
First Question:
1. First thing I look for is how many spots are there and how many of them are for each color: both green and orange have 1 spot each out of six spots.
2. The chances of landing on each one is 1/6.
3. Now that they have to land back to back, I multiply the fractions by using the denominator which is 1 in 36 or 1/36.
Second Question:
1. Once again I see there are eight spots and blue has 3 of those.
2. I multiply the chance of it landing on blue on the first time, 3/8, by itself for the second time, 3/8.
3. You multiply the fractions and you get 9 in 64 or 9/64.
Step-by-step explanation: The y-intercept is where the line on a graph crosses the y-axis. For example Y=2x-2. The line crosses the y-axis at (0,-2). So the Y-intercept would be (0,-2)
When we look at Y=mx+b (slope intercept form)
M being the slope and B being the Y intercept.
So to write it as an ordered pair you just need to put 0 in place of the x-coordinate. So (0,-2)
