Answer:
Barry travels 4mph. Robin travels 5mph. Therefore Robin is walking faster.
Step-by-step explanation:
2x2=4
36/60=0.6
0.2=1
0.2x5=1
1x5=5
D) you just multiply the numerator and denominator by 6 to get an equivalent fraction
Answer:
Total cost for 2.80 hours = ($255/hr)(2.80 hrs) = $714.
Step-by-step explanation:
Multiply this hourly rate by the elapsed time (2.80 hours):
Total cost for 2.80 hours = ($255/hr)(2.80 hrs) = $714.
For systems of equations try using graphing, substitution, and elimination. For example
{2x+7y=3}
{x=-4y}
You should first look at if you have a variable that can be substituted (using substitution) and in this case we do! you plug in the x into 2x meaning 2(-4y)+7y=3
1) distribute -8y+7y=3
2) combine like terms in this case -8y+7y= -1y
3) solve -1y=3
y=-3
so currently our solution is (0,-3)
now we solve for x.
we plug our solved variable (y) into 7y
7(-3) and our equation looks like this
2x+7(-3)=3
1) distribute 7(-3)=-21
2) rewrite then solve 2x+(-21)=3
3) isolate variable -21+21 & 3+21
4) 2x=24
5) solve 2/24 = 12
Meaning our solution is (12,-3)
This is how to solve by substitution.
