Answer:
m<−18
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
m+12<−6
Step 2: Subtract 12 from both sides.
m+12−12<−6−12
m<−18
Answer: the number of adult tickets is 210
The number if student tickets is 270
Step-by-step explanation:
Let x represent the number of adult tickets that were purchased.
Let y represent the number of student tickets that were purchased.
At the ritz, concert tickets for adults cost $6 and tickets for students cost $4. If the cost of total tickets purchased is $2340, then,
6x + 4y = 2340 - - - - - - - -1
Total number of tickets purchased is 480. This means that
x + y = 480
x = 480 - y
Substituting x = 480 - y into equation 1, it becomes
6(480 - y) + 4y = 2340
2880 - 6y + 4y = 2340
- 6y + 4y = 2340 - 2880
-2y = - 540
y = - 540/-2 = 270
x = 480 - 270
x = 210
Answer: her weekly allowance= 16
Step-by-step explanation:
Imani spent half of her weekly allowance playing golf.
Let her weekly allowance be x
Imani spent x/2 playing golf.
Her parents gave her 4.00 for washing car. This means she has additional 4 .00 for washing car besides x
She has a total of x + 4
What was her weekly allowance if she had 12.00 left? This means after spending x/2 on playing golf, she still had 12.00 left from the total of (x +4)
That is
(x +4) - x/2 = 12
Taking LCM of 2 on the left hand side
2(x+4)-x =12
(2x + 8 - x)/2 =12
2x - x +8 = 12×2 = 24
x +8= 24
x = 24-8 = 16
her weekly allowance= 16
Check
16/2)+4 = 12(what she had left)
