David is saving money to buy a game. So far he has saved $30, which is one-third of the total cost of the game. How much does the game cost

$90

Step-by-step explanation:

= $30   1 • 30 = 30

= $60   2 • 30 = 60

= $90   3 • 30 = $90

= 1 whole

1 whole = $90

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
