Answer:
-1y+1x-2
Step-by-step explanation:
if you are combining like terms this is how you do it at all of the same variables together to simplify the expression
On simplifying the expression 13.8+ (-11.5) , we get 2.3 . And additions
13.8 + (-11.5) and (-13.8) + 11.5 are numbers will same value and opposite sign.
<h3>What are rules for adding a positive and a negative number?</h3>
For adding a negative and a positive number, use the sign of the larger number and subtract.
For example: (–8) + 2 = -6
Given that we have to solve 13.8 + (-11.5) = 13.8-11.5 (we subtract smaller no from larger and will use the sign of lager number that is + here)
13.8+(-11.5) = 13.8-11.5 =2.3
13.8+(-11.5) simply means that 13.8 -11.5 which is subtraction of 11.5 from 13.8
but (-13.8) + 11.5 = -13.8 +11.5 = -( 13.8 -11.5) [taking -1 common from the expression]
Therefore , -13.8 + 11.5 has same value as 13.8- 11.5 but opposite in sign.

Answer:
Area of the shaded area = 60 m^2
Step-by-step explanation:
Remark
I don't think you need the 40 degrees for anything.
Formula
Area of Shaded part = area of the rectangle - area of the triangle
Solution
<u>Area of the Rectangle</u>
L = 12 meters
W = 10 meters
Area = 12 * 10
Area = 120 m^2
<u>Area of the triangle</u>
Area = 1/2 b * h
b = 12
h = 10
Area = 1/2 * 12 * 10
Area = 120/2 = 60
Area of the shaded area
120 - 60 = 60
A- 98+89+123=310 (boys)
A-102+105+117=324 (girls)
B-324-310=14 I found my answer by subtracting the girls from the boys and I got 14
C-They will need to hire 24 more teachers because if you add the students together you will get 644 then you divide it by 20 and you get 32 but since they already have 8 teachers you would just subtract 8 from 32 wich you get 24
