Answer:
Jim's claim is correct
Step-by-step explanation:
Total survey=100 people
Morning exercise=35 people
Afternoon exercise=45 people
Night exercise=20 people
Morning exercise : Total survey
=35 : 100
Afternoon exercise : Total survey
=45 : 100
Night exercise : Total survey
=20 : 100
Jim's claim is correct because in finding the ratio, one has to relate it with the total people involved in the survey.
Tara's claim however seems to relate one variable with two other variables
Example:
35 : 55
Morning exercise : (morning exercise + night exercise)
35 : (35+20)
35 : 55
Check the pictures below.
make sure your calculator is in Degree mode, since the angles are in degrees.
Answer:
2x-12
Step-by-step explanation:
First you distribute the -2 to the x and +3
this will make you expression be:
4x-6-2x-6
you then do -6+-6
this will make your expression be:
4x-12-2x
After you get this you have to combine like terms. the like terms in the expression are the two with x being you variable. 4x and -2x.
Once you have combined like terms your solution should be:
2x-12
You would do
(1.1)(80,000,000)=88,000,000
That is the total cars for year two. To find the increase you would do
(1.1)(88,000,000)=96,800,000
Then you would subtract year 2 from year three
96,800,000-88,000,00=8,800,000
That gives you ur answer.
