*IGNORE THE ANSWERS*
This is 2nd grade math. I forgot how to solve these equations. Help:)

a. 14

b. 7

Step-by-step explanation:

a. First we must add all the animals together,

Total Animals:

Birds: 6

Fish: 5

Mammals: 11

Reptiles: 3

Therefore our equation is:

6 + 5 + 11 +3 = 25.

Now, we must subtract by the number of mammals:

25 - 11 = 14

So our answer for a. is 14!

b. So for this problem we must compute mammals + fish and than birds + reptiles. After we figure that out we must subtract them!

Mammals + Fish =

11 + 5 =

16

Next,

Birds + Reptiles =

6 + 3 =

9

Now, let us subtract them,

16 - 9 =

7

So our answer for b. is 7 more animals!

the "equation" answer is 25

Step-by-step explanation:

6+5=11

11+3=14

11+14=25

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
