The system would equal (1.65,-0.25)
You can use substitution for this. But first we need to put one of the equations into the value of y or x. We can use 5x+y=8 and solve for the value of y. Subtract 5x on both sides and you’ll get the value of y which will look like y=-5x+8.
Next substitute in y for 5y in 5x+5y=7 so that you get 5x+5(-5x+8)=7. Next distribute and you’ll get 5x-25x+40=7, add like terms and you’ll get -20x+40=7. Next you want to subtract by 40 on both sides and you’ll get -20x=-33. Isolate x by dividing by -20 on both sides and you’ll get x=33/20 or 1.65.
Next that you have the x value solve for y by plugging in 1.65 for x in 5x+y=8 and you’ll get 5(1.65)+y=8, distribute and subtract 8.25 on both sides and it will leave you with y=-0.25.
I think the answer would be B, because if your body gets it proper nutrients, it should be able to stay healthy. :)
C. examining the health of the tire isn’t a rocket science. Anyone
with a little knowledge of the tires can examine the tire and tell if it needs replacement.
For instance the fact that proper air pressure in the tire needs to be
maintained, depending the weather to better utilize the car power and increase
the life of the tire.
