1. 80% of the students on a field trip love the movie. If there are a total of 50 students on the field trip, how many love the movie?​

40 students

Step-by-step explanation:

A helpful tip I use is x% of y= y% of x

For example, 50% of 80 is 40

Boom

40 kids liked the movie

Step-by-step explanation:

A percentage can also be used as a decimal. For example, 80% becomes 0.80, and 5 percent becomes 0.05. To figure out the answer with decimals, multiply the original number, in this case 50, by the decimal, and you get your answer.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
