Do the opposite to the x..if it was -2x you plus that
Answer:
x = 5
Step-by-step explanation:
Using the tangent ratio and the exact value
tan60° = , then
tan60° = = = ( multiply both sides by 5 to clear the fraction )
x = 5
Answer:
16 students got an A
Step-by-step explanation:
Set up an equation to compare the ratio to the scores:
Cross multiply:
80 = 5x
Divide each side by 5:
x = 16
Now, check if
16/8 = 2
40/8 = 5
The ratios are the same! Therefore, 16 students got an A!

Answer:
These are called supplementary angles.
Step-by-step explanation:
Supplementary angles are equal to 180 degrees. 100 + 80 is equal to 180 degrees, meaning that the angles are supplementary. I hope this helps! :)
For this item, we let x be the amount of the white chocolate in the candy. With this representation and given that there is 3 lbs of peppermint sticks, the total mass of the candy is x+3.
Since white chocolate comprises the 75% of the candy, we make an equation that is,
x / (x + 3) = 0.75
The value of x from the equation is 9 lbs.
