Answer:
28 shirts
Step-by-step explanation:
Let's see what we are given.
there are x amount of shirts ($616 total)
there are 12 in a dozen
the regular shirts are $16
the last 12 shirts are $14
Lets make an equation.
616= 14(12) + 16x
616=168+16x
448=16x
x=28
(Sorry if this explanation is bad)
Answer:
The length of the rectangle is 159923.5 and the width of 53289.5
Step-by-step explanation:
We will make 2 equations one that is the perimeter and another that is the length with respect to the width
b = w*3+55
2b + 2 w = 426426
we will replace b with (w * 3 + 55) in the second equation
2b + 2 w = 426426
2(w*3+55) + 2w = 426426
we clear w to find its value
6w + 110 + 2w = 426426
8w = 426426 - 110
8w = 426316
w = 426316/8
w = 53289.5
Now that we have the value of w we replace it in the first equation and solve to find b
b = w*3 + 55
b = 53289.5*3 + 55
b = 159868.5 + 55
b = 159923.5
I couldn't understand the last part, I think they are just options
The last part should be x>-9
Hope it helps!

Answer: 2 and 17/20 mm is the total thickness of the stack.
Step-by-step explanation:
Get the values you need for the dime and the penny from the chart:
dime: 1 and 7/20mm , penny: 1 and 1/2mm
Find common denominators for the fractions given in the chart.
20 will work because 1/2 is the same as 10/20.
Add the numerators of the fractions: 7 + 10 = 17 so the fraction will be 17/20
Add the whole numbers 1 + 1 = 2
Put it all together and now you've got 2 and 17/20 mm
