Step-by-step explanation:
Find 1 pack of pencil:
1 pack = 10 ÷ 5 = $2
9 packs = 2 x 9 = 18
Answer: $18
Answer:
50
Step-by-step explanation:
The total salary was $3650.
The base salary is $3500.
$3650 - $3500 = $150
He made $150 in commission.
He makes $12 commission for every $100 he sells.
$150/$12 = 12.5
He sold 12.5 amounts of $100.
Each $100 corresponds to 4 cases.
12.5 × 4 = 50
He sold 50 cases of coffee.
Answer:
10 degrees F
Step-by-step explanation:
The temperature at 9 pm was -8
3 hours earlier is was 18 degrees warmer
T at 6pm = -8 +18
=10
Answer:
3) x = 15; 95 and 85 4) x = 12; 98 for both angles
Step-by-step explanation:
2x + 65 + 3x + 40 = 180 Set the equations equal to 180
5x + 105 = 180 Combine like terms
- 105 - 105 Subtract 105 from both sides
5x = 75 Divide both sides by 5
x = 15
Plug 15 into both equations
2(15) + 65 = 95
3(15) + 40 = 85
4) 5x + 38 = 9x - 10 Set the equations equal to each other
- 5x - 5x Subtract 5x from both sides
38 = 4x - 10
+ 10 + 10 Add 10 to both sides
48 = 4x Divide both sides by 4
12 = x
Plug 12 into both equations
5(12) + 38 = 98
9(12) - 10 = 98
Step-by-step explanation:
The number n is - 5
Because the sum = 8 + (-5) = 3
After multiply by - 4 = 3 x - 4 = - 12
Option A is the correct answer
