Carlos is five years older than twice his sister's age. Carlos is 13. Which equation and solution correctly identifies his sister's age? 2x - 5 = 13; x = 9
2x + 5 = 13; x = 4
2x - 5 = 13; x = 4
2x + 5 = 13; x = 9

Find the balance at the end of 4 years if 1000 is deposited at the rate of

X+ y = 5 ; x - y =3 solve using linear combination

The graph and table shows the relationship between y, the number of words jean has typed for her essay and x, the number of minutes she has been typing on the computer. according to the line of best fit, about how many words will jean have typed when she completes 60 minutes of typing? 2,500 2,750 3,000 3,250
