You buy 8 packs of markers with 20 markers in each pack. You already had 10 markers. Which equation shows how to calculate the total number of markers, m, you have?

a. m=20⋅8−10

b. m=10⋅8+25

c. m=8⋅20+10

d. m=8+10

c

Step-by-step explanation:

you mulitply 8 and 20 then add ten to find m

C

Step-by-step explanation:

Given : The number of markers in each of 8 pack = 20

Then, the number of markers in 8 packs = 8 x 20 = 8(20)

Also, You already had 10 markers.

Then, the total markers you have now =  Number of markers in 8 packs+ 10

= 8(20)+10

If we denote the total number of markers be 'm'.

Then, the required equation will be :-

Hence, the equation shows how to calculate the total number of markers, m, you have : m=[20]+10

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
