Hypothetically. Relli’s in DeWitt had 30 workers in their restaurant in the year 2010. In 2011 they let go 20% of their workers due to budget cuts. In 2012, they are letting go another 10%. How many workers will they have at the beginning of 2013? Round to the nearest whole worker.
At the beginning of 2013, they would have 22 (21,6) workers.
30-20%(6)=24
24-10%(2,4)=21,6

What is the solution of this system?
-2y-8=-4x
-y-4x=-2
look at all of this math. do it all or something for 50 points each ig
(a + b)2 = a2 + 2ab + b2
(a – b)2 = a2 – 2ab + b2
(a + b) (a – b) = a2 – b2
(x + a)(x + b) = x2 + (a + b)x + ab
(x + a)(x – b) = x2 + (a – b)x – ab
(x – a)(x + b) = x2 + (b – a)x – ab
(x – a)(x – b) = x2 – (a + b)x + ab
(a + b)3 = a3 + b3 + 3ab(a + b)
(a – b)3 = a3 – b3 – 3ab(a – b)
(x + y + z) 2 = x2 + y2 + z2 + 2xy + 2yz + 2xz
(x + y – z) 2 = x2 + y2 + z2 + 2xy – 2yz – 2xz
(x – y + z)2 = x2 + y2 + z2 – 2xy – 2yz + 2xz
(x – y – z)2 = x2 + y2 + z2 – 2xy + 2yz – 2xz
x3 + y3 + z3 – 3xyz = (x + y + z)(x2 + y2 + z2 – xy – yz -xz)
x2 + y2 = 1212 [(x + y)2 + (x – y)2]
(x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
x3 + y3 = (x + y) (x2 – xy + y2)
x3 – y3 = (x – y) (x2 + xy + y2)
x2 + y2 + z2 -xy – yz – zx = 1212 [(x-y)2 + (y-z)2 + (z-x)2]

I hope this helps you. sorry if it's wrong.
2.5(12.75x + 24.50) = 188.75
1. Simplify both sides of the
equation
(remove parentheses
and/or combine like terms).
2. Use inverse operations and
properties of equality to
"undo" what is happening to
the variable. (use the
reverse order of operations
because we are undoing)
3. Check your answer by
substituting your answer
into the original equation.
Answer:
Step-by-step explanation:
First, in order to get rid of the parenthesis, you need to multiply 2.5 with whatever is in the parenthesis.
Multiply 2.5 on each side of the equation like this:
(12.75 x 2.5) (24.50 x 2.5) =188.75
Once you're finished, you should get 61.25 and 31.875x =188.75
Now in order to find 'x' you will need to subtract 61.25 to each side of the equation like this:
61.25 - 61.25 = 0
188.75 - 61.25 = 127.5
So now your equation should look like this:
31.875x = 127.5
You have to divide 31.875 by each side now.
Once you divide them, your final answer should be 4.
so x = 4.
I really hope this helps! ^^

Answer:
x= 35° hope this helps!!!
Answer: 35°
Step-by-step explanation: the total of a triangle's angles always equals 180° and we know 2 of the angles so if you add the two (55+90=145) and subtract that from 180 (145-180=35) you get 35°

Solve the proportion. 1.4/2.5 = g/25
Answer:
g=14
Step-by-step explanation:
Solve for g by simplifying both sides of the equation, then isolating the variable.
Answer:
g = 14
Step-by-step explanation:
If you divide 25 by 2.5, you get 10, so if you multiply 1.4 by it, you get 14. In this proportion, the ratio is 1 : 10
