5x−y=3<br> −5x+2y=4<br> Which ordered pair satisfies the system of equations shown above?
ale4655 [162]

Answer:

(2, 7)

Step-by-step explanation:

We can solve this system of equations by using elimination.

In this case, we can eliminate x by adding the two equations:

5x+(-5x)-y+2y=3+4\\5x-5x+y=7\\y=7

Then, substitute 7 for y to solve for x:

5x-y=3\\5x-7=3\\\text{Add 7 to both sides}\\5x=10\\\text{Divide both sides by 5}\\x=2

Substitute both these values into the system to check our answer:

5x-y=3\\5(2)-7=3\\10-7=3\\3=3\rightarrow \text{correct!}

-5x+2y=4\\-5(2)+2(7)=4\\-10+14=4\\4=4\rightarrow \text{correct!}

Therefore the ordered pair is:

(x, y)=(2, 7)

Answer:

A: 30 m

B: 14 boxes

C: $596.40

D: $477.12

Step-by-step explanation:

A: 6*4.2 = 25.2.  3.2*1.5 = 4.8.  25.2 + 4.8 = 30.

B: 30/2.15 = 13.95, which rounds to 14.

C: 14*42.60 = $596.40

D: 20% off 100% = 80%, which is equal to 0.8.    596.40*.8 = $477.12.

Hope it helps you!! :)

arlik [135]
Walk - \frac{1}{3} h
Ride - \frac{1}{2}h
Journey took \frac{1}{3}+\frac{1}{2} = \frac{2+3}{6} = \frac{5}{6} h = 50 minutes
and \frac{1}{2} it's a \frac{3}{5} of time
