<u>Equivalent Fractions</u>
Two fractions are equivalent if they represent the same rational number, regardless of their expression. For example, the fraction 2/5 is equivalent to 10/25 since they both represent the number 0.4
To find if a given fraction is equivalent to another given fraction, we can simplify or amplify it until an equivalence is found or not. We can also simply perform the division and compare the results.
We must find out if the four choices are equivalent to the fraction 4/9. Let's start with the first one
We simplified it by 4 and found it's not equivalent to 4/9. The fraction
is equivalent to 4/9 when simplified by 2.
This fraction was simplified by 3 and is not equivalent to 4/9. Finally
Is equivalent to 4/9 when simplified by 3. Summarizing, these fractions are equivalent to 4/9
Answer:
1(18 + 6)/4
Step-by-step explanation:
1(18 + 6)/4
PLEASE MARK ME AS BRAINLIEST!!!
Well, first of all, you have to open up the bracket by multiplying what's outside by what's inside. Anyway;
3k-15=-16
Next, you have to collect the like terms and put them together. And the -15 becomes +15. So;
3k=-16+15
3k=-1
Next, you have to divide the both sides by 3. So;
3k/3=-1/3
k=-1/3
So your answer is -1/3. Hope i helped. Have a nice day.
Answer:
8 units
Step-by-step explanation:
In a 45°- 45°- 90° triangle the legs are congruent, thus
3x - 10 = x + 2 ( subtract x from both sides )
2x - 10 = 2 ( add 10 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Thus
3x - 10 = 3(6) - 10 = 18 - 10 = 8
Since legs are congruent then they are both 8 units
