Answer:

D.) eCafé, the equation is C = $0.20M + $7.00, and I'll save $2.00

Step-by-step explanation:

Log-On Café: $6.25 plus $0.25 for every minute online

c = 6.25 + .25m

cost for 55 minutes

c = 6.25 + .25 (55)

c = 6.25 + 13.75

c = 20.00


eCafé: $7.00 plus $0.20 for every minute online

c = 7 + .2m

cost for 55 minutes

c = 7 + .2 (55)

c =7+11

c = 18


The e cafe is less expensive  (20-18)  by 2 dollars

Find the value of x.<br> 33°<br> 107°<br> x
Kaylis [27]

Answer:

140

Step-by-step explanation:

Angles in a triangle add up 180 :

180 = 107 + 33 + y

y = 180 - (107+33)

y = 180 - 140

y = 40

Angles on a straight line add up to 180 so :

180 = x + y

180 = x + 40

x= 180 - 40

x = 140

Hope this helped and have a good day

Part A Simplify:

Answer is - 12b + 6c + 18



Part B

Answer is (D)

Factor/simplify
- 12b + 6c + 18

6(- 2b + c + 3)
= (6)(- 2b + c + 3)
= (6)(- 2b ) + (6)(c) + (6)(3)
= - 12b + 6c + 18

therefore,- 12b + 6c + 18; Factored in GCF is 6(-2b + c + 3)





- 12b + 6c + 18
reorder the terms
18 + 12b + 6c

Factor out the GCF " 6"
6(3 + 2b + c)


Final Result:
6(3 + 2b + c)



Hope this helps
