H = 3000 - 40m (starts at 3000...decreasing at 40 ft per minute
h = 1200 + 50m (starts at 1200...rises 50 ft per minute
Answer:
1=(w=6,C=20.80
2=(W=2,C=27.05)
3=(w=11,C=14.25)
4=(w=15,C=11.05)
Step-by-step explanation:
Just do the work
0.55x15=8.25+2.80=11.05
1.10x6=6.6+14.20=20.8
11x0.65=7.15+7.10=14.25
Out of process of elimination, 2=(W=2,C=27.05)
Answer:
38
Step-by-step explanation:
|-7|×|5|+18÷|-6|
First take the absolute value of each number, which means take the positive value
7×5+18÷6
Multiply and divide from left to right
35 + 3
Then add
38
Answer:
x = 4
Step-by-step explanation:
f(x) = 4x-5
11 = 4x-5
4x-5 = 11
4x = 11+5
= 16
x = 16÷4
= 4
Advanced ($10): A
Door ($13): D
Money: 10A + 13D = 544 ⇒ 1(10A + 13D = 544) ⇒ 10A + 13D = 544
Quantity: A + D = 46 ⇒ -10(A + D = 46) ⇒ <u> -10A - 10D</u> = <u>-460 </u>
3D = 84
D = 28
Quantity: A + D = 46 ⇒ A + (28) = 46 ⇒ A = 18
Answer: advanced = 18 people, at the door = 28 people
