Answer:
L = 2,
O = 31
Step-by-step explanation:
First using the givens, write out some formulas.
Heavy equipment operators = O
General laborers = L
- O + L = 33
- 138O + 87L = 4044
Now use substitution, it doesn't matter which one you substitute.
- O = -L +33
- 138( -L + 33 ) + 87L = 4044
Distribute and solve for L.
- -138L + 4554 + 87L = 4044
- -138L - 87L = 4044 - 4554
- -225L = -510
- L = -510/-225
- L = 2
L = 2, meaning number of laborers employed is 2.
Now plug 2 = L into one of the original equations.
- O + L = 33
- O + 2 = 33
- O = 33 - 2
- O = 31
O = 31, meaning number of heavy equip. operators employed is 31.
Hmmm i can’t really see its kinda blurry sorry
Answer:
Perimeter: 6x+8
Area: 2x²+8x
Step-by-step explanation:
Perimeter- the sum of all sides
So, you do x+4+x+4+2x+2x
Simplify that to- 2x+2x+2x+8
And also simplify that to- 6x+8
Area- length*width
So, it's (x+4)*2x
which is 2x²+8x
Answer:
do you have a picture?
Step-by-step explanation:
I can't go off of just that (not enough info)
I might just give two of them.
28. y=45°,
13x13=169
169/2=84.5
√84.5=x
x=2√21+√2/2
31. (5√2)²=50
50/2=25
x=√25=5
(5√2)²+(5√2)²=100
y=√100=10
Those are your answer.
