Answer:
y=(5/3)x
Step-by-step explanation:
Since y varies directly with x, then the constant of proportionality is equal to k=y/x. Since y/x=20/12=5/3, then k=5/3. This means the equation to relate x and y is y=(5/3)x
Answer:
Step-by-step explanation:
All equations where x=2 is a solution : a(x-2) = 0......a ≠ 0
Answer:
1. x = 10
(triangle has equal side lengths)
2. x = the same number inside the triangle
(is that a 40 or 80?)
3. x = 34
(is that a 34?)
4. x = the number shown on the other side of the triangle
(is that a 55?)
5. if the given number is 8 then x = 11
(11-3=8)
6. x = 11
(2x-15=7)
7. x = 5
(65+5=70)
8. x = 10
(5x-10=40)
9. m<2 = 9
(7x-3=60)
10. m<2 = 8
(x+72=80)
hope this helps!
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
