I'm pretty sure it would be C
because 0.17 is how much he has to pay for each message sent and if x is the total messages he sends then it should be 0.17X+24.07
Answer:
1)52
2)5
Step-by-step explanation:
use PEMDAS
1) 21+36-15÷3. 2) 51÷3-4×3
15÷3= 51÷3=17
21+36-5. 17-4×3=12
21+36= 17-12=
57-5= 5
52.
Answer:
4*5*7=140 ways
Step-by-step explanation:
First he has to decide on a pair of pants and he has 4 different choices.
For each of those choices he has a choice of 7 different shirts, so that gives him 4 times 7 = 28 different pant/shirt combinations. (I hope none of the pants are striped and none of the shirts have polka-dots).
For each those 28 possibilities, he has 5 different ties he could select, so altogether he has 28 times 5 = 140 different outfits, and some of them may be acceptable to wear in public.
It is simply , 4*5*7=140 ways.
Step-by-step explanation:
(x1,y1) = (6,-1)
(x2,y2) = (3,-7)
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y + 1)/(-7 + 1) = (x - 6)/(3 - 6)
(y + 1)/-6 = (x - 6)/-3
(y + 1)/2 = (x - 6)/1
y + 1 = 2(x - 6)
y = 2x - 12 - 1
y = 2x - 13
