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
Step-by-step explanation:
I've used elimination method over here but it can also be done by using substitution.

Answer: 126 5p coins
Step by step explanation:
1p+2p+5p = 630
2p= 2/5 of 630
2p= 252
1p= 2( 5p)
630 - 252 = 378
378/3= 126= 5p
378-126= 252 = 1p
252+252+126= 630
Perpendicular = opposite sign and reciprocal slope
Y = 3/2x + 1
The slope is 3/2, opposite sign = -3/2 now reciprocal = -2/3
Y = -2/3x + b
Plug in the point (6,-2)
-2 = -2/3(6) + b
-2 = -12/3 + b
-2 = -4 + b, b =2
Solution: y = -2/3x + 2
