The equation would be
314 = 0.4(x) + 250
Would you like me to explain?
So first x = 9x = The answer is
2x-9x=0
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 
−10
fish left = 10
Therefore, the additive inverse of the number of fish left is −10. The sum of a number and its additive inverse is 0.
10 + (−10) = 0 A is the answer
since you have the 75, we know that a would equal 105 for line g , since a line = 180 degrees
so to make line f parallel with g it needs the same angles with line n as line g has
so if a = 105, then angle d would also need to be 105
The answer is D
