Answer: a. Total cost = 3g+2
b. The total cost of 8 games is $26.
Step-by-step explanation:
Given: Cost to bowl a game = $3
Shoe rental charge = $2 (One -time charge)
Total cost = (Cost to bowl a game) x (Number of games)+ (Shoe rental charge )
Let g= number of games, then the expression to find the total cost will be :
Total cost = 3g+2
To find the total cost of 8 games, put g=8, we get
Total cost = 3(8)+2
= 24+2 = $26
Therefore , the total cost of 8 games is $26.
Depends on what time their bedtime is, like if their bedtime is at 6:00, and they have to wake up at 5:00 then their waking hours would be 11 hours.
Answer:
Expression
Step-by-step explanation:
2,3, and 7 are coefficient .
x and y are constant
Answer:
...
against the wind, an airplane travels 3640 km in 7 hours.
with the wind, the same plane travels 6000 km in 6hrs.
...
let speed of plane in still air be x mph
speed of wind be y mph.
..
t=d/r
..
against wind speed = x-y mph
with wond speed = x=y mph
...
3640/(x-y)=7
3640 = 7x-7y
/7
520=x-y.....................1
...
6000/x+y = 6
6000 = 6x+6y
/6
1000=x+y.....................2
...
Add (1) & (2)
2x=1520
/2
x=760 mph speed of plane in still air
...
plug value of x in 2
1000=760+y
100-760=y
240 = y
240 mph speed of wind
