Answer:

Step-by-step explanation:

Find LCM of 4,5,8 = 40

Then find equivalent fractions

2/4 = 2*10/4*10 = 20/40

3/5 = 3*8/5*8 = 24/40

6/8 = 6*5/8*5 = 30/40

20/40+24/40+30/40 = (20+24+30)/40

= 74/40 = 37/20

Answer:

Step-by-step explanation:

1) Change the fractions so that they all have common denominators (2/4 --> 20/40,  3/5 --> 24/40,  6/8 --> 30/40)

2) Add the numerators together (74/40)

3) Simplify as necessary

Nerissa paid a total of $8 for 4 packs of pencils she purchased from the convenience store. Let p represent the cost of one pack
BARSIC [14]

Answer: 4*p=8

Step-by-step explanation:

<em>You can use inverse operation to answer this equation.</em>

  • <em>write out you problem: 4 x p =8</em>
  • <em>The inverse of multiplication is division</em>
  • <em>you do 4/4 which gives you one but the 4 will cancel itself out</em>
  • <em>Do 8/4 which gives you 2</em>
  • <em>under the equation write p = 2</em>
  • <em>And be sure to line the p up with the p, the equal sign with the equal sign, and  the 2  stays where it is ( which should be already lined up with the 8)</em>

The expression -3m - [2m + (5 - m)] + 7 was simplified as 2 - 4m. Without simplifying, explain how you can show that it has been
Rina8888 [55]

Answer:

Step-by-step explanation:

g(m) = 0

2-4m=0

2=4m

2/4=m

1/2=m------(1

p(1/2)= -3(1/2) - { 2(1/2) + (5- 1/2) } +7

= -3/2 - { 1 + 9/2} +7

= -3/2 - ( 11/2) +7

=-14/2 +7

= -14 + 14 /2

= 0/2

= 0...

since p(m)= 0,

we can say that g(m) is a factor of p(m)

hence, it has been simplified correctly...
