Answer:
Texting speed
Step-by-step explanation:
It's the dependent variable
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
Answer:
Step-by-step explanation:
5z-6-34=z-6
combine like terms (-6-34)
5z-40=z-6
subtract z on both sides
5z-z-40=-6
4z-40=-6
add -40 on both sides
4z=34
divide both sides by 4
z=

<h3>
Answer: 4.5 meters</h3>
Work Shown:
The keyword "of" means "multiply".
150% = 150/100 = 1.5
150% of 3 = 1.5*3 = 4.5
.05n + .10d = 6.10
n + d = 67
n = 67-d
.05(67-d) + .10d = 6.10
3.35 -.05d + .10d = 6.10
3.35 + .05d = 6.10
3.35-3.35 +.05d = 6.10-3.35
0.05d = 2.75
0.05d/0.05 = 2.75/0.05
d = 55
n + d = 67
n + 55 = 67
n = 12
There are 12 nickels
Check
0.5(12) + .10(55) = $6.10
.60 + 5.50 =$6.10
$6.10 = $6.10
