When you see a coefficient (the number next to the letter) next to a variable (the letter), you multiply. So 3*2=6 So you have: 6+y, or since y=-1, 6+(-)1= 5

3(2) + -1
6-1=5

6-1 is from the 1 being a negative already.

2 At Bea's Pet Shop, the number of dogs, d, is initially five less than twice the number of cats, c. If she decides to add three

forsale [732]

Let D be dogs and C be cats

dogs, d, is initially five less than twice the number of cats, c

D + 5 = 2C

If she decides to add three more of each, the ratio of cats to dogs will be

D + 8 = 2C + 3

Could Bea's Pet Shop initially have 15 cats and 20 dogs?

Simply plug in the numbers

20 + 5 = 2(15)

This is clearly not true: 25 does not equal 30

The spinner shown is divided into congruent sections that are labeled from 1 through 7. If the spinner is spun one time, what is

adoni [48]

Answer:

3/7

Step-by-step explanation:

The number of possible results are;

1, 2 , 3 , 4 , 5, 6 , 7 = 7

odd numbers here are;

1, 3 , 5 and 7

non-odd numbers are 2, 4 and 6

So the section not labeled with an odd number is 3

Hence the probability here is that;

3/7
