Answers:
In these exercices are ilustrated the representations of the fractions
2) Firstly, we have 3 equal segments, each one representing
, hence:
is <u>3</u> copies of
Let's prove it, taking into account we are adding fractions with the same denominator:

There are <u>4</u> equal parts that make a whole
Four copies of <u>
</u> make
or <u>1</u> whole

3) Here we have a line divided into four segments, each one of
. Hence:
This is
of a line.
is <u>4</u> lengths of

If we draw one more
we will have
or 1 whole.
Then:
<u>5</u> lengths of
make
or <u>1</u> whole.
4) In this part the answer is in the attached image. If we have two equal segments, each one of
we will have as a result
.
If we add another
segment, we will have three segments of
, having as a result 
Answer:
11 mommas!
Step-by-step explanation:
4505 divided by 405.45 is 11.11... Of course, you can't fit 11.11... mommas, so the answer is just 11.
Answer:
f(g (x))= 32x-18
g (f (x))=32x2+42
Step-by-step explanation:
f (g (x))= 4 (8x-6)+6
32x-24-6
32x-18
g (f (x))= 8(4x2+6)-6
32x2+48-6
32x2+42
18 - 12 = 6. Because the top legs of the 2 triangles are congruent, you divide 6 / 2 to get 3 as their length. Then you can use the Pythagorean Theorem to solve for x.
3^2 + x^2 = 14^2
9 + x^2 = 196
x^2 = 187
x = sqrt(187)
I’m assuming that you only need the answer to the last one but let me know if I’m wrong :)))
I believe C would be 23.6
