Answer:
Michael worked 4 hours and Landon worked 10 hours.
Step-by-step explanation:
Michael can iron 40 shirts each hour, so in xx hours he can iron 40x40x shirts. Landon can iron 20 shirts each hour, so in yy hours he can iron 20y20y shirts. The total number of shirts ironed 40x+20y equals 360:
40x+20y=360
40x+20y=360
Since Michael and Landon worked a combined 14 hours, we know x+yx+y must equal 14.
x+y=14
Write System of Equations:
40x+20y= 360
x+y=14
Solve for y in each equation:
40x+20y = 360 x+y = 14 20y = -40x+360
=
y = -2x+18
Answer: x=2π/3 and x=4π/3
Step-by-step explanation:
The equation we have is 
. All we have to do is get cosine alone to find the 2 values of x.
Now that we have our cosine left, we can use our unit circle to figure out when does cosx=-1/2. Cosine is the x value of the coordinate.
x=2π/3
x=4π/3
Answer:
a = (r/x) -b
x = -14
Step-by-step explanation:
r=x(a+b)
Divide each side by x
r/x = a+b
Subtract b
r/x -b = a
x/2=-7
Multiply each side by 2
x/2*2 = -7*2
x = -14

Answer:
$7.7
Step-by-step explanation:
Hello, I can help you with this
you can solve this by using a simple rule of three.
Step 1
define
if the wholesale price for a shirt is $5.50,it is 100 percent
$5.50⇔100%
the new price(x) is 40% more than the original, it means 140%
x ⇔ 140%
the relation is
Step 2
solve for x(isolate x)
the price of the shirt in the department store is $7.7
Have a nice day.
