Answer:
x=12
Step-by-step explanation:
we know that the sum of the angles in a triangle is 180 degrees
to find x we have to calculate the sum of the angles
(10x-11)+(3x-2)+(3x+1)=180
10x-11+3x-2+3x+1=180
16x-12=180
16x=180+12
16x=192
x=192/16=12
A. is correct kkkkkkkkkkkkkkkkkk
Step-by-step explanation:
f(x) = 4x-5
g(x) = 2x
(f + g)(x)=f(x) +g(x)=4x-5+2x=6x-5
Answer:
get 1 … what? free? half-price? something else?
Let x= price of 1 item
Then 3x= price of 3 items
Buy 2 , get 1 free
Total cost =2x
Discount =3x−2x=x
Discount percentage =x/(3x)=0.333…=3313%
Buy 2 , get 1 half price
Total cost =2x+0.5x=2.5x
Discount =3x−2.5x=0.5x
Discount percentage =0.5x/(3x)=0.1666…=1623%
