Maria opens a savings account with $50 and then saves $19 each week. How many weeks will it take for her account to reach $259? Represent this problem with an equation in the form px+q=r .(1 point)
Responses
259+50=19x
259 plus 50 equals 19 x
19x−50=259
19 x minus 50 equals 259
50x+19=259
50 x plus 19 equals 259
19x+50=259

2x+7=15
2 x plus 7 equals 15
15−7=2x
15 minus 7 equals 2 x
2x−7=15
2 x minus 7 equals 15
7−2x=15
Responses
2x+7=15
2 x plus 7 equals 15
15−7=2x
15 minus 7 equals 2 x
2x−7=15
2 x minus 7 equals 15
7−2x=15
7 minus 2 x equals 15

We can represent this problem with an equation in the form px + q = r, where p represents the amount deposited each week, x represents the number of weeks, and r represents the target amount in the account.
In this problem, p = 27, q = 100, and r = 343. We want to find the value of x.
So the equation becomes 27x + 100 = 343.
To solve for x, we can subtract 100 from both sides of the equation: 27x = 243.
Then, we divide both sides of the equation by 27: x = 9.
Therefore, it will take Destiny 9 weeks for her account to reach $343.

We can represent this problem with an equation in the form px + q = r, where p represents the difference in the number of games, x represents the number of games played last season, and r represents the number of games played this season.
In this problem, p = 12, x represents the number of games played last season, and r = 21. We want to find the value of x.
So the equation becomes 13x + 12 = 21.
To solve for x, we can subtract 12 from both sides of the equation: 13x = 9.
Then, we divide both sides of the equation by 13: x = 9/13.
Therefore, Ahmadullah's basketball team played approximately 0.69 games last season. Since we can't have a fraction of a game, we can round up to 1 game.
Therefore, Ahmadullah's basketball team played 1 game last season.

We can represent this problem with an equation in the form px + q = r, where p represents the difference in the number of games, x represents the number of games played last season, and r represents the number of games played this season.
In this problem, p = 12, x represents the number of games played last season, and r = 21. We want to find the value of x.
We are given that this season, the team will play 12 games more than 1/3 the number of games they played last season. Mathematically, this can be represented as:
21 = (1/3)x + 12
To solve for x, we can subtract 12 from both sides of the equation: (1/3)x = 21 - 12 = 9.
Next, we multiply both sides of the equation by 3 to isolate x: 3 * (1/3)x = 3 * 9.
This simplifies to x = 27.
Therefore, Ahmadullah's basketball team played 27 games last season. The correct answer is 27 games.

Joseph wants to buy tickets for the baseball game and a team hat to wear to the game. He has $34.25. If the hat costs $12.50 and tickets cost $7.25 each, how many tickets can he buy?
To determine how many tickets Joseph can buy, subtract the cost of the hat from the total amount of money he has:
$34.25 - $12.50 = $21.75
Then, divide the remaining amount of money by the cost of each ticket:
$21.75 / $7.25 = 3
Therefore, Joseph can buy 3 tickets.
$34.25 - $12.50 = $21.75
Then, divide the remaining amount of money by the cost of each ticket:
$21.75 / $7.25 = 3
Therefore, Joseph can buy 3 tickets.
