Step-by-step explanation:
time ∝ number of door 1
time . ∝ 1/number of people. 2
compare equation 1 and 2
time . ∝ number of door / number of people
put k as constant
time = k number of door / number of people. 3
time =2. people=4 door = 10
putting in equation 3
2 = k (10)/(4)
2×4/10 = k
8/10 =k
4/5 =k
putting in equation 3
time= 4/5 number of door / number of people
now time =5 door= 25 people=?
5=4/5 (5)/ (number of people)
number of people =4/5 ×25/5
number of people= 4
Your answer would be 185.24 due to cash back subtracting from deposits for the total on the green line
Answer:
FIRST ONE
Step-by-step explanation:
Answer:
y = 4x - 8
Step-by-step explanation:
x = 1/4y + 2
-1/4y -1/4y
-1/4y + x = 2
-x -x
-1/4y= -x + 2
*-4 *-4
y = 4x - 8
Hello!
We need to get a number that is greater than or equal too 120. First of all, let's calculate the sales tax.
120(0.07)=8.4
120+8.4=128.4
This gives us the inequality below.
7.5w+44≥128.4
Now we solve like an equation.
7.5w≥84.4
84.4/7.5≈11.25
w≥11.25
As you can see, the only number greater than 11.25 is D) 12 weeks which is our answer.
I hope this helps!
