Answer:
1) 80 people 2) 15 weeks
Step-by-step explanation:
(x = the number of people)
500 + 8x = 1140 ← ($500 initially plus $8 per person equals $1140)
8x = 640 ←(subtract the $500 from each side)
x = 80 ←(divide by the $8 per person to get the number of people)
------
(x = the number of weeks)
242 = 62 + 12x ←(The cost of the snake ($242) is equal to her $62 plus $12 she saves every week)
180 = 12x ←(subtract the $62 from both sides)
15 = x ←(divide by the $12 per week)
Answer:
47.33
Step-by-step explanation:
Hey there! I'm happy to help!
We have 8 bags of dog food and each costs $25.19
8(25.19)=201.52
And we have 11 leashes each costing $4.65.
11(4.65)=51.15
We add these totals up.
201.52+51.15=252.67
We subtract this from 300 to see how much is left.
300-252.67=47.33
Rhonda had $47.33 left after her purchases.
Have a wonderful day! :D
Answer:
He bought 1 small bag and 6 large bags.
Step-by-step explanation:
We can set up 2 equations with the given information.
5x+8y=45
x+y=6
We can rearrange the second equation to solve for x.
x=6-y
Now we substitute x for 6-y in the first equation
5(6-y)+8y=45
30-5y+8y=45
30+3y=45
y+10=15
y=5
x=1
He bought 1 small bag and 6 large bags.
Answer:
2) -2/3
4) 17/5
Step-by-step explanation:
2)-4/3= 2g
-4=6g
g=-2/3
4) 9=5r - 8
-5r=-17
r=17/5
