if the humpback whales had traveled at the same rate for 32 days,how many more miles would the have traveled than the grey whale
Nataliya [291]

Answer:

192 miles more than the gray whales.

Step-by-step explanation:

first, get the rate of each whale per day. To put it in simpler terms, divide 2,240 miles by 28 to find how much the humpback whales travel in a day. next, do the same for the gray whales. I got that the humpback whales traveled 80 miles in a day and the gray whales traveled 74 in a day. Multiply 80 miles by 32 days to get the distance the humpback whales travel in 32 days (2,560 miles). Since you know the distance the Gray whales traveled in 32 days, you do not need to solve for it. Subtract 2,560-2,368 and you get 192 miles.


Hope this helped. If you can, label this answer as brainliest. Dont hesistate to ask if you have any questions. <3

Mrs. Carter is ordering pizza for her math class. She will need to pay a $15 delivery fee and then $7 for each pizza she orders.
Natali [406]

Answer:

A) 7p+15

Step-by-step explanation:

To first start things off, we know she automatically has a fee of 15 dollars. No matter what, she must pay the 15 dollars!

Using this information, we know that so far we have: 15+

We also know that it costs 7 dollars for one pizza. If Mrs. Carter decides to buy more then just one pizza then how will we express it? We can express by writing 7x. The reason we have a x with the 7 is because x is the total amount of pizzas.\

Now we combine what we have.

15+7x= the total amount of dollars for x pizzas bought!

I hope this helps! :)

(Side Note: if she gets 2 pizzas you plug in 2 for x.)
