Answer:
240 students
Step-by-step explanation:
Grade 7 : Grade 8 = 5 : 3
Number of seventh grade students = 5x
Number of Eighth grade students = 3x
3x = 90
x = 90÷3
x = 30
Total students = 5x + 3x = 8x = 8 * 30 = 240
Answer:
Nickles: 96 times
Penny: 48 times
Step-by-step explanation:
5+3+8+4 = 20 coins in total
20x = 240
x=12 (chance of a coin being picked)
8 nickles(12) = 96
4 pennies(12) = 48
It C. and if you need the equation for the area of a parallelogram its A=BH
(2^6)^x=1
(4)^x=1
(4)^0=1
1=1
X=0
(5^0)^x=1
(1)^x=1
x=(-∞,∞)
