Answer:

$2.4b+4c$

Step-by-step explanation:

Simplify:

$-0.8b+4.1c-(-3.2b)-0.1c$

then;

$-0.8b+4.1c+3.2b-0.1c$

Like terms are those which have same variable to the same power.

Combine like terms;

$2.4b+4c$

Therefore, the simplified form of the given expression is, $2.4b+4c$

-0.8b+4.1c-(-3.2b)-0.1c
-(-3.2b)= 3.2b
4.1c-0.1c=4c
-0.8b+4c+3.2b
-0.8b+3.2b=2.4b

4c+2.4b

During a promotional weekend a state fair gives a free admission to every 175th Person who enters the fair on Saturday there wer

emmasim [6.3K]

Answer:

Step-by-step explanation:

If every 175th person gets free admission, that means

175th

175 * 2 = 350th

175 * 3 = 525th

person gets free admission and so on...

This basically means "how many 175s are there is 6742 (for first day) and 5487 (for 2nd day)?"

We would need to divide and see the WHOLE number, not the fractional(decimal) amount remaining. So

1st Day:

6742/175 = 38.53

This means 38 people will get free admission

2nd Day:

5487/175 = 31.35

This means 31 people will get free admission

In the 2 days, total of 38 + 31 = 69 people will get free admission

Solve the system of equations using the substitution method. y=2+1/4x,

skelet666 [1.2K]

Answer: (4,3)

Step-by-step explanation:

1. In this method you must solve one of the equation for one of the variables and substitute it into the other equation to find the other variable. Then, substitute the value of that variable into one of the original equation to obtain the value of the other one.

2 You have that:

$y=2+1/4x$

3. Then, you can substitute it into the other equation and solve for x:

$3x-5(2+1/4x)=-3\\3x-10-5/4x=-3\\7/4x=7\\x=4$

4. Now you can obtain y:

$y=2+1/4x$

$y=2+1/4(4)\\y=3$

5. The answer is:

(4,3)
