lacy went to the fair. She paid $5 for the entrance fee. Each ride ticket cost $0.25. Lacy spent $12.50 at the fair. Which equation can be used to find how many ride tickets Lacey bought?

$0.25r + $5 = $12.50
$0.25r + $5r = $12.50
5r + $0.25 = $12.50
$0.25r - $5 = $12.50

Answers

Answer:

$0.25r + $5 = $12.50

Step-by-step explanation:

r represents the amount of rides Lacy went on during the day. If you do the problem in the correct order, you will get the answer

Step 1)

Subtract 5 from both sides

$0.25r + 5 (-5) = 12.50 (-5)

Step 2)

Divide by 0.25

0.25r (Divided by 0.25) = 7.50 (Divided by 0.25)

Step 3)

Answer

r = 30 rides

$0.25r+$5=12.50 this is because you will have to subtract 5from both sides and then divide the sum( which is $7.50) by $0.25. So lacy purchased 30 tickets

Answer:

The answer is 420.

Step-by-step explanation:

Because since we know it wants 140 grams of fish. And twice as many pasta than fish. You can simply just do this: 140 x 2 = 280. So 140 + 280 will = 420. There you go!

420 grams
Do 140 x 2 to get the pasta (double the fish) to get 280. Then add the grams of fish back 280 + 140 which equals 420 grams

b(x-h) -a(y-k) = 0

A graphing calculator shows the point of intersection of the graphs of the two lines to be (x, y) = (-1, 3), so the line perpendicular to 2x+5y=5 through that point can be written ...

2. The chances of landing on each one is 1/6.

3. Now that they have to land back to back, I multiply the fractions by using the denominator which is 1 in 36 or 1/36.

Second Question:

1. Once again I see there are eight spots and blue has 3 of those.

2. I multiply the chance of it landing on blue on the first time, 3/8, by itself for the second time, 3/8.

3. You multiply the fractions and you get 9 in 64 or 9/64.
