Answer:
For 1 Day: $85
For 2 Days: $110
For 3 Days: $135
For 4 Days: $160
Step-by-step explanation:
For 1 Day: $25 + $60 = $85
For 2 Days: ($25 * 2) + $60 = $110
For 3 Days: ($25 * 3) + $60 = $135
For 4 Days: ($25 * 4) + $60 = $160
Answer:
x=-33/5 y=29/5
Step-by-step explanation:
Let's solve your system by substitution.
3x+y=−14;2x−y=−19
Solve
3x+y=−14 for y:
3x+y=−14
3x+y+−3x=−14+−3x(Add-3x to both sides)
y=−3x−14
Next is to substitute −3x−14 in for y 2x−y=−19:
2x−y=−19
2x−(−3x−14)=−19
5x+14=−19(Simplify both sides of the equation)
5x+14+−14=−19+−14(Add -14 to both sides)
5x=−33 Dived both sides by 5
5x/5=-33/3
x=−33/5 since you can't dived and a fraction is another form of division you keep it this way.
Step: Substitute -33/5 for x in y=−3x−14:
y=−3x−14
y=−3(-33/5)-14
y=29/5
(Simplify both sides of the equation)(since you can't dived and a fraction is another form of division you keep it this way.)
So
x=-33/5 and y=29/5
Pls mark brailest this took me a long time to write out lol. Hope this truly helps! Send a heart if so, so I can keep spreading the help!

Answer:
0.25 miles per minute, travels 5 miles in 20 minutes
Step-by-step explanation:
First, we have to find out how many miles he can travel in a minute.
We know that he travels 15 miles every hour, and we know that one hour is 60 minutes.
- 15 mi./ 1 hr = 15 mi. / 60 minutes
So, we can divide 15 miles by 60 minutes in order to get his pace for miles per minute
- 15 ÷ 60 = 0.25 miles per minute
Then we can just multiply 0.25 miles by 20 minutes
which gives us 5 miles in 20 minutes
