*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

people went from manufacturing one object at a time by hand to manufacturing many objects in factories

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
