If you Just divided -11u and 44 by -11 u equals 4
Answer:
solution set is (x,y) = (7,6)
Step-by-step explanation:
solving by substitution method
2x +y=20--------------1
6x-5y=12---------------2
from equation 1, solve for y
2x+y=20
y= 20-2x------equation 3
adding value of y in equation 2
6x-5y=12
6x-5(20-2x)=12
6x-100+10x=12
16x= 12+100
16x= 112
x= 112/16
x=7
adding value of x in equation 3
y= 20-2x
y= 20- 2(7)
y=20-14
y=6
so solution set (x,y) = (7,6)
Answer:
Step-by-step explanation:
cot(-11pi/6)=cot(-pi-5pi/6)= -cot(5pi/6)=cot(pi/6)=≈1.73
Answer
9/10=<u>90%</u> and 2/5=<u>40%</u>
Explanation
9÷10=0.9 0.9x100=90%
2÷5=0.4 0.4x100=40%

<span>Here the given equation is :
2-8x= -6
By bring -6 on the Left Hand size and taking 8x on the Right Hand side, the equation become.
2+6= 8X
8= 8X
X=8/8
X=1
Hence value of X is 1.
Hence correct option is A.</span>
