Answer:
D. Cannot be determined without seeing the data.
Step-by-step explanation:
Option “D” is correct because age is a quantitative variable but if we look at the exact number or exact age of the car then the car’s age is quantitative discrete but if we look at the age of the car by going a number of years then it will be continuous. Therefore, without getting the exact information of the age of the car we cannot predict the type of variable. So the option “D” best fit for the answer.
A + b + c = 12
c = (a + b) - 2.....c - a - b = -2
3a + 1 = 2c
add the first 2 equations
a + b + c = 12
-a - b + c = -2
------------------add
2c = 10
c = 5 <== longest side is 5
sub in 5 for c in the 3rd equation
3a + 1 = 2c
3a + 1 = 2(5)
3a + 1 = 10
3a = 10 - 1
3a = 9
a = 3 <== shortest side
now sub in 5 for c and 3 for a back into the first equation
a + b + c = 12
3 + b + 5 = 12
b + 8 = 12
b = 12 - 8
b = 4 <== other side
I'm learning the exact same thing so give me some question and I can see what I can do!
Do you mean this number:
?
The we have to simplify the fraction part, since the nominator is bigger than the denominator.
How many denominators fit into the nominator? 20: 4=5
5! so
is simply 5 and we can add it to the main number:
175+5=180
Yes you are right the answer or whatever you're trying to say is also multiplication is also the new addition and subtraction dividing is the new multiplication addition and subtraction so try doing what was best like multiplying first if that's better or dividing first if that's better
