Let x = roller coaster ticket
let y = boat ride ticket
x + y = 10
4x + 3y = 37
x = 10 - y
4x + 3y = 37
4(10-y) + 3y = 37
40 - 4y + 3y = 37
-y = 37 - 40
-y = -3
y = -3/-1
y = 3
x = 10 - y
x = 10 - 3
x = 7
x = 7 ; y = 3
4x + 3y = 37
4(7) + 3(3) = 37
28 + 9 = 37
37 = 37
Part time job Allowance 20/wk
3 h fri
6 h sat
total 92.00 find: per hr part time
92-20=72
3+6=9
72/9 = $8 part time per hour
$5500×1.12= $6160. same method as the previous answer I gave you:)
Answer:
8 -2/x
Step-by-step explanation:
"The quotient of 2 and x" means "2 divided by x". Written using math symbols, that is 2/x. Eight minus this value is written ...
8 -2/x
(b) 40 *
= 40 *
= 8
(c) 360 - (72 + 144 + 81) = 360 - 297 = 63
(d)
=
