The  fraction of the total books about mammals is 7/18

Let the total number of books in the school be 1 whole , ie 12/12( since we are dealing with fractions)

Number of science books =7/12

Number of mammals books =2/3 of science books

=2/3  x 7/12=14/36 = 7/18

Since the total books are 12/12 which is also =1 whole

Then the fraction of total books that are about mammals are 7/18 x 1 whole =7/18

stiks02 [169]
The answer to this question is 600-28w > 300. This inequality can be described as $600 (money in the savings account) subtracted by $28w (withdrawal of $28 a week for food) should be greater than $300. It proves that the money will not drop below $300.

Solve for x in the diagram below (picture included)
Sever21 [200]

Answer:

34

Step-by-step explanation:

We know the straight line is equal to 180°, and the three angles that make it are (x+12),100°, and x. We can use the equation 180=(x+12)+100+x to find x.

180=(x+12)+100+x

We can remove the parentheses and combine x plus x to 2x.

180=100+2x+12

100+12=112

so

180=112+2x

-112 -112

68=2x

÷2 ÷2

34=x
