30 + 75x= 210
Subtract 30 from both sides
75x=180
Divide both sides by 75
X =2.4
Worked 2.4 hours
Answer:
30% of her writing utensils are pencils.
Step-by-step explanation:
We can get this by dividing the number of pencils by the total number of utensils.
6/20 = .3 = 30%
Every triangle has an angle measure of 180 degrees.
so 42+20+x (where x is the measure of the third angle)=180
Combine like terms.
62+x=180
Subtract 62 from both sides
x=118.
The answer could be 3, 2, or 1
