Answer:
2 game, $12
Step-by-step explanation:
Given data
Showplace Lanes charges
$4.50 per game as well as
$3 for shoe rental
Let the number of games be x
let the total charge for x games be y
y= 4.5x+3-----------1
Westgate Bowling charges
$4 per game and $4 for
shoe rental
Let the number of games be x
let the total charge for x games be y
y= 4x+4-----------2
Equate 1 and 2
4.5x+3= 4x+4
collect like terms
4.5x-4x= 4-3
0.5x= 1
divide both sides by 0.5
x= 1/0.5
x= 2 games
put x= 2 in equation 1 or 2
y= 4x+4-----------2
y= 4*2+4
y= 8+4
y= $12
I couldn't answer the second part of the question because it didn't say if it was from a list or anything, so I didn't know what the question was. But the answer to the first part is that it would be 314 inches tall in 3 weeks.
Here's an explanation:
The problem said that the plant was already 212 inches tall. Then the problem mention that the plant grows 34 inches in each week. Since you need to find how much it could grow in 3 weeks, you would do 34 multiplied by 3, which is equal to 102 inches. Since the plant is already 212 inches, you add 102 to 212, which is equal to 314 inches. So, the plant is 314 inches tall.
Answer:
1. b=39.497
2. c=3.606
3. a=18.974
Step-by-step explanation:
1.
41^2-11^2=b^2
1681-121=b^2
b^=1560
b=39.497
2.
2^2+3^2=c^2
4+9=c^2
c^2=13
c=3.606
3.
21^2-9^9=a^2
441-81=a^2
a^2=360
a=18.974
