Answer:
I am pretty sure the answer is 498.
Step-by-step explanation:
You have to solve the parentheses first. So,
9(7 (14-6) -3 x 2)
63 (8) -6)
63(8)-6
63(8) = 504
504-6 = 498
please let me know f this is correct :)
<span>Krystal's rate = 1 floor in 16 min. = 1/16 floors per min.
Working together their rate = 1 floor in 5.76 min. = 1/5.76 floors per min.
We need to determine Perry's rate, so we need to equate their combined rate with the sum of the individual rates.
Let Perry's time = x
In equation form, we can write:
1/16 + 1/x = 1/5.76
Solve for x:
(x+16)/16x = 1/5.76 -> 5.76(x+16) = 16x -> 10.24x = 92.16 -> x = 9
So, Perry would take 9 mins. to do the floor alone.
I hope this helped!

Answer:
7.5 hundredths (7 hundredths and 5 tenths) equals 3/4
Step-by-step explanation:
Given the dimension of the length and area of the rectangle, the dimension of the breadth x is 9in.
Hence, option A is the correct answer.
This question is incomplete, the missing diagram is uploaded along this answer below.
<h3>What is the value of x?</h3>
Area of a rectangle is expressed as; A = l × b
Given that;
- Length of the rectangle l = 20in
- Breadth b = x
- Area A = 180in²
A = l × b
180in² = 20in × x
x = 180in² / 20in
x = 9in
Given the dimension of the length and area of the rectangle, the dimension of the breadth x is 9in.
Hence, option A is the correct answer.

Answer:
Let s be the number of shorts and t be the number of T-shirts. s shorts cost $12s and t T-shirts cost $5t, then you have to find min and max value for the function f(s,t)=12s+5t.
The shaded domain (see image) is defined from the system of unequalities. The green lines are the graphs of function f(x,y) and it intersects domain in first point (0,5) (the minimum point) and in last point (20,0) (the maximum point). So,
.
