Solution,
y = -x-4......(i)
3x + y =- 16.......(ii)
Now,
Substituting the value of y in equation (ii)
or, 3x + (-x-4)= -16
or,3x - x - 4 = -16
or, 2x= -16 +4
or, x = -12/2
: x = -6
Then,
Substituting the value of x in (i) equation;
or,y= -(-6) - 4
or,y= 6 - 4
: y =2

Step-by-step explanation:
because it gave u an angel and and adjacent so your x is the opposite so sin20=x÷17 just use your calculator u will find the ans
V=Bh what is the height of the prism? You do (35^2 )(height)
Answer:
x = 10
m<A = 132 degrees
m<B = 48 degrees
Step-by-step explanation:
Supplementary = angles that make up 180 degrees
We know <A and <B are supplemntary, so 2x+28+6x+72 = 180.
8x + 100 = 180
8x = 80
x = 10
I input 10 into the equations to solve for the measures of the angles
The better one is a pack 30 pencils that costs $7.97. How do I know I divide 7.97/30 and got 0.26567. I did the same thing to the other one and got 0.3975. The one that is smaller is the best one.
