Answer:
3x +(-2) = 2x + 4
Step-by-step explanation:
green sticks represents positive 3x and red boxes represents negative 2 since it's a equation modeled on adding it is shown as 3x+(-2) = 2x+4
Let n be the 40%, and 100-n be the 10%. Then:
.4n+.1(100-n)=.22(100)
.3n+10=22
.3n=12
n=40

Answer:
9x² + 5x
Step-by-step explanation:
4x² + 6x + 5x²-x
Combine like terms:-
4x² + 5x² = 9x²
6x - x = 5x
9x² + 5x
-----------------------------
the sum of all the angles = 180
13x-11 + 8x-9 + 30x-4 =180
51x-24 = 180
51x = 204
x=4
w= 8x-9= 8×4-9
= 2e°
