Peter's account is 910-40x, and Marla's account is 470-2x. This is a system, so you must find the number that makes both equations end up with the same number. Basically trial and error. Here is what I did:
Let's try the number 10. 910-400=510 and 470-20=450. I need a higher number.
Let's try 13 next. 910-520=390 and 470-26=444. Now the number has to be lower.
Let's try 12. 910-480=430 and 470-24=446. Close, and a little lower.
11.5 is too low, and 11.7 is too high. 11.6 has Equation 1 at 446 and Equation 2 at 446.8. Very close!
It is somewhere around 11.6. I hope that this can give you a start in figuring it out, because I don't believe in giving the complete answer, because then you do not learn anything from it.
The answer for 6x+2=14 is x=2.
Answer:
Graph the points, (2,18) (7, 24) and (16, 0)
Step-by-step explanation:
Going to the store takes 2 minutes for 18 blocks, which is the first point
He stays at the store for 2 minutes then takes 3 minutes to get to the bank which is 6 blocks away, add the time together and blocks, and you get the second point
He stopped at the bank for 3 minutes and the drove back home. It takes him 6 minutes to get back home, (24/6), add all the minutes together and you get 16.
(This is assuming the graph is y for blocks and x for minutes)
Answer:
28p^2+22p-30
Step-by-step explanation:
I'm a genius
6x+1 = 12x because the Z angles are the same
Solve this and you get:
1 = 12x - 6x => x = 1/6
