the actual answer is 20 units
Step-by-step explanation:
Answer:
probs c
Step-by-step explanation:
c bc 3x>21 is x>7
the smallest whole number out of the multiple choice answer that fits into the solution is 8
Estimate: 6 5/6 rounds to 7 and 1 1/5 rounds to 1 so the estimate is 7/1 which is 7
Find: make the terms both improper fractions: 41/6 and 6/5
Flip the second term and multiply: 41/6 * 5/6
The answer is 205/36
Let's write down what we know:
a=50+b
b=30+c
After one hour:
(a+50)*2=-70+3*(c+50)
let's eliminate the brackets:
2a+100=-70+3c+150
2a+100=+3c+80
which is:
2a=-20+3c
substituting from a=50+b:
100+2b=-20+3c
substituting from b=30+c
100+2(30+c)=-20+3c
100+60+2c=-20+3c
160+20=3c-2c
180=c.
So we know that c is equal to 40, then b will be b=30+c
b=30+180=210.
So B had 210 miles initially.
Answer:
Range = 7
Mode = 1
Step-by-step explanation:
Given the data
8, 1, 1, 6, 2, 2, 1, 1,8
Range = Highest value in the data - Lowest value in the data
Highest value = 8
Lowest value = 1
Range = 8 - 1
Range = 7
The mode is the data value that is occurring most. from the set of data, we can see that 1 is occurring four times (most frequent). Hence the mode of the data is 1
