Answer:
x=3
Step-by-step explanation:
The equation will be 3+6x=21 since we know that the soft drink costs 3 dollars and he bought 6 candy bars(6 times x or 6x). We also know that the total cost for this merchandise is 21 dollars. Now you solve the equation! First subtract 3 from both sides(since the inverse for addition is subtraction we SUBTRACT 3 from bothe sides). You are left with 6x=21-3 or 6x=18. Now you divide Each side by 6(because the inverse operation of multiplication is division). You have the answer! x=18/6 or x=3! Hope it helped!!
Answer:
9x+2
Step-by-step explanation:
the inverse of the function is the opposite. 1/9 becomes 9 and negative 2 becomes positive 2
Answer:
B) 2771 cubic centimeter
Step-by-step explanation:
first find the volume of the cylinder
V=πr^2h
V=3.14*7^2*26
V=4002.39
then find the volume of the cone
V=πr^2h
/3
V=3.14*7^2*24/3
V=1231.5
subtract the volume of the cone from the cylinder
4002.39-1231.5
2770.89
round to the nearest whole number
2771
Answer: 1%
Step-by-step explanation: Total 2,000
BioChem Lab: 25% of total = 25% . 2000 = 500
LabRep: 45% of Lab = 45% . 500 = 225
There will be 9 LabRep: 225/9 = 25
Participation: 10% of LabRep = 10% . 25 = 2.5
Actual LabRep: 90% of LabRep = 90% . 25 = 22.5
So, each lab report is worth 22.5 of 2000 = 2.5/2000 = 0.01125 = 1.125%
Nearest whole number = 1%
Y=3x-14
y-intercept=-14
x intercept=14/3 or 4 and 2/3
