Prove your answer using the values of the ratio.
100 of your friends listen to it
- Total Number = 100
Rachel said the ratio of the number of the people who liked the playlist to the number of people who did not like the playlist is 75:25.
The ratio can be simplifies further by diving all through by 25;
75/25 : 25/25
3 : 1
Dylan said that for every three people who liked the playlist, one person did not.
This simplifies to 3 : 1.
Same thing with what rachel said, so they both agree
The equation x° = 180° - (37°+ 53°) can be used to find the value of x.
Step-by-step explanation:
Step 1; There are three lines in the given diagram. There are a baseline and two other lines. Out of the other two lines, one extends above and below the baseline whereas the other extends only above. Since the baseline is horizontal and the others are at angles we have the sum of all the three angles as 180° i.e. 37°, x°, and 53°.
37° + x° + 53° = 180°.
Step 2; To solve the value of x, we keep the unknown value at the left-hand side whereas all the known values are taken to the right side of the equation.
x° = 180° - (37°+ 53°).
So the fifth option can be used to determine the value of x.
Answer:
29 and 17
Step-by-step explanation:
Sum: 29 + 17 = 46
Difference: 29 - 17 = 12
F(x) = 3x + 1
let f(x) = y
y = 3x + 1
y - 1 = 3x
3x = y - 1
x = (y - 1)/3
From y = f(x), x = f⁻¹(y)
<span>x = (y - 1)/3
</span>
f⁻¹(y) = (y - 1)/3
f⁻¹(7) = <span>(7 - 1)/3 = 6/3 = 2
</span>f⁻¹(7)<span> = 2</span>
