Answer:
y=11
x=8
Step-by-step explanation:
This is Elimination
2x+2y=38
Subtract 2x on both sides 2y=-2x+38
Then Multiply 2(y=x+3) which equals 2y=2x+6
Solve by Elimination
2y=-2x+38
2y=2x+6
add the y's and since the x's are different those cancel out, then add 38 and 6.
then you do the equation 4y=44
divide both by 4
y=11
then you do 11=x+3
subtract 3 on both sides
x=8
and there you go
I hope this is how you wanted it solved
The decimal form for 2/10 would be 0.2.
The choices you typed in were confusing.
A. 20
B. 2.0
C. .2
D. 2.10
The correct answer would be C. .2.
Answer is B. 200 miles
{(y/50)+2} hour=y/30 hour gives y=150 miles. Since, the train already had covered 50 miles at full-speed before the cylinder blew, so the run between the stations was 50+150=200 miles.
Hi, thank you for posting your question here in Brainly.
Celsius and Fahrenheit are units of temperature, and they can be converted using a formula.
F = C*1.8 + 32
For example, 30°C is
F= 30*1.8 + 32
F = 86°F
Or an easier way to remember without memorizing the formula is by remembering the normal boiling point of water which is 100°C = 212°F.
Hi there!
Your question:
Sales fall from 300 per week to 270 per week what's the percentage change?
My answer:
The formula for calculating percent change is as follows:
[(y2 - y1)/y1]*100=your percent change
y2= first value
y1=second value
Plug the numbers in:
[(300-270)/300]*100
[30/300]*100
0.1*100
10
Therefore, the percent change is 10%
Hope this helps! Let me know if it's incorrect so I can fix it:)
