a recipe for 1 handmade pizza calls for 2 1/2 cups all purpose flour. Showing your work below, how many cups of all purpose flou

KatRina [158]

You need to use the cross product method to find your answer :

1 pizza = 2 ½ cups
3 pizzas = × cups

((2 ½) • 3) ÷ 1 = × cups

7 ½ ÷ 1 = × cups

7 ½ = × cups

⇨ So your answer is: You would need to use 7 ½ cups of flour to make 3 handmade pizzas!

There you go. I really hope this helped, if there’s anything just let me know! ☻

Kareem and Christine each ran every day as part of an exercise routine. Kareem ran 5 miles each day for x days. Christine ran 6

stellarik [79]

$5x \geq 6y$
The inequality above shows the relationship.

In this case, Kareem miles on the left have to be at least as much as Christine's on the right.

It would read: 5x is greater than or equal to 6y.

4 bells toll together at 9 am. They toll after 7, 8. 11 and 12 seconds respectively. How many times will they toll together agai

Svetach [21]

Answer:

5 times

Step-by-step explanation:

What we need to do here is to find the lowest common multiple of 7,8,11 and 12

This is;

1848

Now, let’s calculate the number of seconds in 3 hours

In 1 hour, we have 3600 seconds

In 3 hours, this will be;

3600 * 3 = 10,800 seconds

So, to find the number of times in which all 4 will toll together, we need to know the number of 1848 seconds in 10,800 seconds

Mathematically, that will be;

10,800/1848 = 5.844

Our answer will be 5 times however

This is because the sixth time they would have sounded together would be more than the 3 hours time frame
