Answer:

The distance between them in half a minute was 130 m

Step-by-step explanation:

Firstly, we will find distance traveled by first and second puppy and then we can find distance between them

First Puppy:

Speed =1.5 m/sec

time =0.5 min =30 second

we know that

distance = speed*time

d_1=1.5\times 30 m

d_1=45m

Second Puppy:

Speed =2.5 m/sec

time =0.5 min =30 second

we know that

distance = speed*time

d_2=2.5\times 30 m

d_2=75m

now, we can find distance between them

so,

The distance between them is

=250-(d_1+d_2)

=250-(45+75)

=130m

So,

the distance between them in half a minute was 130 m

In the equation 2y=18, determine which property of equality will be used to isolate the variable. Choose the best answer. A. Mul
mixer [17]

Answer:

(C) Division Property of Equality

Step-by-step explanation:

Looking at the equation 2y=18, we see that if we want to isolate y, we need to divide it by 2 - because we're multiplying it by 2, and 2 times a number divided by 2 is just the number.

The Division Property of Equality states that if we have an equation, a=b, then a\div c = b\div c.

So, that means 2y\div 2 will be equal to 18 \div 2, which is 9.

Hope this helped!
