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!! :)

A MAN walked for 1/3 hour and then got an automobile ride for 1/2 hour. what part of time consumed he ride on automobile ????

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
