The answer is 6 8/9, because they have a common denominator so you just add the nominator, and for the whole number you add it regularly.

Line a is parallel to line b, m 6=85, and m 3=2x. Find m 1.

Paladinen [302]

Since a line =180 degrees you could set it up as (180-85) and you would get 95.
Hope this helps!!!

A math test is worth 100 points and has 38 problems. Each problem is worth either 5 points or 2 points. How many problems of eac

Nat2105 [25]

Answer:

5 points question is 8

and 2 points questions is 30 !!

Step-by-step explanation:

Let the number of 5 points questions be x and number of the 2 points questions be y !!

Given :- The paper has 38 problems

i.e,

number of 5 points Q + number of 2point Q = 38

=> x + y = 38

=> x = 38 - y .... ( i )

And , The test worth 100 pts :-

There must be x number of Questions which carry 5 points and there must y number of questions which carries 2 points ( as assume above )

so, 5x + 2y = 100 .... ( ii )

Putting value of the x in ( ii )

5 ( 38 - y ) + 2y = 100

190 - 5y + 2y = 100

- 3y = - 90

y = 30

Putting value of y in ( i )

x = 38 - y

x = 38 - 30

x = 8

So, the Number of 5points Question is

x = 8

and , the number of 2 points questions is y = 30 !!

The |6f|= -2 I don't understand what to do

aleksandr82 [10.1K]

First you are going to solve for f.

6f = -2

you must get f alone so you divide both sides of the equation by 6 which becomes ....

f = -3

now you add the absolute value sign to -3. absolute value is how far away your answer is from 0. -3 is 3 away from zero so f = 3

Provide in simplest form 12% of 40

AnnZ [28]

To get 10% of 40, you move the decimal point one way to the left. So 10% of 40 is 4
Now you need 2% and because you know 10% is 4, you divide that by 10 and multiply it by 2 because of the 2%
4/10=.4 .4•2=.8
Now you add them
4+.8=4.8
12% of 40 is 4.8
