What is 5(4c-2d)+2d-6(d-3c)

Answers

Hi

5(4c-2d) + 2d - 6(d-3c) = 20c - 10d + 2d - 6d + 18c

5(4c-2d) = 5(4c)+5(-2d) = 20c-10d
- 6(d-3c) = -6(d)-6(-3c) = -6d+18c


20c - 10d + 2d - 6d + 18c = 20c + 18c - 10d - 6d + 2d = 38c - 14d

20c+18c = 38c
-10d-6d+2d = -16d+2d = -14d

Answer: 38c-14d 
5(4c−2d)+2d−6(d−3c).Distribute:=(5)(4c)+(5)(−2d)+2d+(−6)(d)+(−6)(−3c)=20c+−10d+2d+−6d+18c.Combine Like Terms:=20c+−10d+2d+−6d+18c=(20c+18c)+(−10d+2d+−6d)=38c+−14d.

Simplify the expression by combining like terms. 1/2d−3/4d+3f−2f

Answers

Answer:

-1/4d+f

Step-by-step explanation:

First find a common denominator for the like terms 1/2d and -3/4d by multiplying 1/2d by 2/2 to get 2/4d.

Now you have common denominators so 2/4d-3/4d=-1/4d.

For the numbers that have a variable of f, 3f-2f=f.

Therefore the answer is -1/4d+f

Factory A can produce 45 machines in 20 minutes. Factory B can produce 30 machines in 15 minutes. If both factories produce machines for 2 hours, wich factory will produce more machines? How many machines will be produced?

Answers

45machines:20mins
20mins=1/3hour
45machines:1/3hour
times 3
135machins=1hour
135machines per hour


B. 30 in 15
15=1/4 hour
30=1/4hour
times 4
120machines per hour

both produce for 2 hours



A. is 135*number of hours, B is 120 times number of hours
135*2+120*2=
270+240=
510

make 510 machines in 2 hours
divide amount a minute by minutes so Factory A= 2.25   Factory B= 2 then multiply those by 2hrs or 120 minutes so 

Factory A = 270 and Factory B = 240
factory A produced more machines
