Answer:
516 students preferred pizza
Step-by-step explanation:
To solve this problem we have to calculate 60% of the total students (860)
To get the percentage of a number we have to divide by 100 and then multiply by the number it indicates, in this case 60
860 %60 = 860 / 100 * 60
860 / 100 * 60 =
8.6 * 60 = 516
60% of 860 is 516
this means that for Friday lunches 516 students preferred pizza

3/5=24/x. cross multiply, you get 120=3x. divide by 3, x = **40**
1/8x+3y=3
subtract 1/8x from both sides
3y=-1/8x+3
divide both sides by 3
y=-1/24x+1
