10 yards per 5min is
10yrd/5min
first convert it into yards per minute
10yrds/5min = 2yrds/1min
let's first so the yards to feet part first
1 yrd = 3 feet
2yrds/min * 3ft/1yrd
so now we have
6yrds/min
now convert minute to hour
1 hour = 60 mins
6yrds/min * 60min/1hr
=360/1hr
remember so that units cancel
Answer:
x=1
y=4
(1,4)
Step-by-step explanation:
TO SOLVE FOR X:
1. Substitute y=x+3 into the equation. This should look like this:
3x+5(x+3)=23
2. Use the distributive property.
3x+5x+15=23
3. Simplify:
8x+15=23
4. Subtract 15 from both sides. It should now lool like this:
8x=8
5. Divide both sides by 8.
x=1
TO SOLVE FOR Y:
1. Take x and substitute into original statement:
3(1)+5y=23
2. Simplify:
3+5y=23
3. Subtract 3 from both sides:
5y=20
4: Simplify:
y=4
CHECK ANSWER:
y=x+3
1. Substitute your answers
4=1+3
2. Simplify
4=4
3. Check for Truth. Is 4=4?
Yes. So your final answer is:
x=1
y=4

Answer:
D
Step-by-step explanation:
An excluded value is any value of x that makes the denominator of the rational expression zero as this would make the expression undefined.
Consider expression D
This will be undefined when
x + 5 = 0 ⇒ x = - 5 ← excluded value → D
Here :
x+4=19-2x
x+2x=19-4
3x=15/3
x=5
If you have some thing like x^2 + x + x^3 + x^2 the correct order would be x^3 + x^2 + x^2 + x.
