solve each system of equations using substitution. x=y+1 x=3y+2
Answer:
x=1/2
y=-1/2
Step-by-step explanation:
x = y+1
x = 3y+2
Substitution means that you solve one equation for a variable by plugging it into the other equation. In this case, the first part is already done for you, and all you have to do is plugging in.
As you're given the value of the x in both equations, it does not matter which equation you plug into. You can plug either equation into one another.
For this, I will show you by plugging in the bottom equation for the top equation.
x = y+1
x = 3y+2
As we know x=3y+2, you must SUBSTITUTE that for the "x" in the top equation.
3y+2 = y+1
From there, you must solve it for the "y" value. In order to solve for the "y" value, you must get the "y" by itself onto one side.
So, subtract y from both sides.
(3y-y)+2 = (y-y)+1
Rewrite the equation.
2y+2 = 1
Remember, the goal is to get the "y" BY ITSELF.
There's a "+2" on the side of the y, so that has to be cancelled out. You can cancel it out by doing the OPPOSITE of adding, which is subtracting. So subtract both sides by 2.
2y+(2-2)=(1-2)
When subtracting a bigger number from a smaller number. The pattern is: Keep it, flip it, flip it.
Keep the 1.
Flip the - to a +
Flip the 2 into a -2.
So you get 1+(-2) which is -1. Now, rewrite the equation.
2y=-1
You want the y by itself. Right now, the y is being multiplied by 2, so you have to do the OPPOSITE, which is division. Divide both sides by 2.
y=-1/2
Now, use this value to plug into your ORIGINAL equations (you can pick either)
x = y+1 OR x = 3y+2
x= -1/2 + 1
x=1/2

C=5(f-32)/9
Make f the subject of the formula
Give answer in the form of aC+b/c
Answer:
F = [tex]\frac{9C+160}{5}[/tex]
Step-by-step explanation:
Given
C = [tex]\frac{5(F-32)}{9}[/tex] ( multiply both sides by 9 to clear the fraction )
9C = 5(F - 32) ← distribute
9C = 5F - 160 ( add 160 to both sides )
9C + 160 = 5F ( divide both sides by 5 )
[tex]\frac{9C+160}{5}[/tex] = F
A train is traveling at a constant speed and goes 7.5 kilometers in 6 minutes. At that rate:
How far does the train go in 1 minute?
how far does the train go in 100 minutes?
Answer:
1.25 km in 1 minute
125 km in 100 minutes
Step-by-step explanation:
Find its speed in km/min by dividing the km by number of minutes:
7.5/6
= 1.25
So, the train goes 1.25 km in 1 minute.
Using this speed, find how far it goes in 100 minutes, by multiplying the speed by 100:
1.25(100)
= 125
So, in 100 minutes, the train goes 125 km.
a. The distance travelled by the train in 1 minute, at a constant speed is 1.25 kilometers.
b. The distance travelled by the train in 100 minute, at a constant speed is 125 kilometers.
Given the following data:
Distance = 7.5 kilometersTime = 6 minutesTo find how far (distance) the train go in 1 minute, we would use direct proportion:
7.5 kilometers = 6 minutes
X kilometers = 1 minute
Cross-multiplying, we have:
[tex]6 \times X = 7.5\\\\X = \frac{7.5}{6}[/tex]
X = 1.25 kilometers.
b. To find how far (distance) the train go in 100 minute:
Since the train travels 1.25 kilometers in 1 minute, we would multiply that distance by 100.
[tex]D(100) = 1.25 \times 100\\D(100) = 125 \; kilometers[/tex]
Distance = 125 kilometers.

Solve for L.
P = 2L + 2W
L = 2/(P - W)
L = 2(W - 2P)
L = (P - 2W)/2
Answer:
L = (P - 2W)/2
Step-by-step explanation:
This is the formula for perimeter
P = 2L + 2W
Sustract 2W on both sides:
P-2W= 2L
Divide both sides by 2:
(P-2W)/2 = L
L= (P-2W)/2

A.$885
B.$15
C.$765

Solve for h.
Thank you!
Answer:
h = -2.5
Step-by-step explanation:
Apply the distributed property: -6h + 8h + 6 = 1Combine like terms: 2h + 6 = 1Subtract 6 from each side, so it now looks like this: 2h = -5Divide each side by 2 to cancel out the 2 next to h. It should now look like this: h = -2.5I hope this helps!
Answer:
h = -2.5
Step-by-step explanation:
-6h + 2(4h + 3) = 1
-6h + 2*4h + 2*3 = 1
-6h + 8h + 6 = 1 {combine like terms}
2h + 6 = 1
2h = 1 - 6
2h = -5
h = -5/2
h = -2.5

A truck can be rented from Company A form $130 a day plus $0.30 per mile. Company B charges $50 a day plus $0.80 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answer:
160 miles
Step-by-step explanation:
Company A form $130 a day plus $0.30 per mile
Company A = 130 + 0.30x
Company B charges $50 a day plus $0.80 per mile
Company B = 50 + 0.80x
Where,
x = number of miles
Equate the cost of company A and company B
130 + 0.30x = 50 + 0.80x
Collect like terms
130 - 50 = 0.80x - 0.30x
80 = 0.50x
Divide both sides by 0.50x
x = 80 / 0.50
= 160
x = 160 miles
The number of miles in a day at which the rental costs for Company A and Company B are the same is 160 miles
