Christine is finding the sum; 28(-15)+22 A: what property of addition could christine use to write the integers in a diffrent or
Flauer [41]

Step-by-step explanation:

I'm sorry if my terminology isn't correct because I've learnt it slightly differently, but what I'm assuming is this:

For A, you can rewrite the integers as 28-15+22 as a + and a - next to each other result in a subtraction.

For B, you simply do 15+22 is 37 and 28-37 is -9 due to BIDMAS (or PEDMAS if you're American).

Two​ high-speed ferries leave at the same time from a city to go to the same island. The first​ ferry, the​ Cat, travels at 34 m
djyliett [7]

Answer:

They will be 5 miles apart in 1 hour

Step-by-step explanation:

Here, we want to calculate the time it will take for the two ferries to be 5 miles apart

Mathematically; distance = speed * time

Let the number of hours be x

In x hours, the cat will have traveled 34 * x = 34x miles

In x hours, the Bird will have traveled 29 * x = 29x miles

So;

34x - 29x = 5

5x = 5

x = 5/5

x = 1 hour
