Answer:
c) The total price for the service when Terrance's price was equivalent to Sylvester's price is $600.
Step-by-step explanation:
Here, t = 320.00 + 0.40 b
and t = The total prices charged by Terrance for packing and moving b boxes.
s = 250.00 +0.50 b
and s = The total prices charged by Sylvester for packing and moving b boxes.
Now, to find the number of boxes, when both the prices are equal.
⇒320.00 + 0.40 b = 250.00 +0.50 b
or, 320 - 250 = 0.50 b - 0.40 b
or, 0.10 b = 70
or, b= 70/0.10 = 700
Hence, for packing and moving b = 700 boxes, both companies charge the same amount.
Now, the price charged = 320 + 0.4 (b)
= 320 + 0.4(70) = 320 + 280
= 600
or, the total price for the service when Terrance's price was equivalent to Sylvester's price is $600.
Hello!
The mean is the average of the data
To find the average you add all the numbers and divide the sum by the amount of numbers you added
14 + 19 + 13 + 22 + 7 = 75
You add 5 numbers so
75/5 = 15
The answer is 15
Hope this helps!
Answer:
23
Step-by-step explanation:
14x2=28-5=23
x = percentage (eg: if x = 3 then this represents 3%)
x/100 = decimal form of the percentage (eg: if x = 3 then x/100 = 3/100 = 0.03)
The equation to solve is
x/100 = 20/104
Cross multiply to get
104x = 100*20
104x = 2000
Then divide both sides by 104 to isolate x
104x/104 = 2000/104
x = 2000/104
x = 19.230769
x = 19.23
So the answer is approximately 19.23%
1. Interchange x and y: x = log₂(y + 7)
2. Solve this resulting equatino for y:
x x
2 = y + 7 => y = 2 - 7
3. Replace "y" with
-1 -1 x
f (x): f (x) = 2 - 7 This is the desired inverse.
