When divided fractions you flip the second fraction
1/5 x 12/1
This then equals
12/5
That simplifies to 2 2/5
Let the number be represented by x
2x=60+ 5x -20*2=60+5*-20
2x-5x=5x-5x+60 -40=60+-100
-3x=60 -40=-40
-3x/-3=60/-3
x=-20
Therefore the number is -20
Answer:
Step-by-step explanation:
I'm pretty sure that the equation for slope is y2 -y1
-----------
x2 - x1
Substitute in the info, and simplify to find the slope.
Answer:
x = 6, z = 5.66 to nearest hundredth.
y = 90 degrees.
Step-by-step explanation:
From the chord intersection theorem 12*4 = 8 * x
So x = 6.
By the tangent / chord theorem:
z^2 = 2 * (12+4)
z^2 = 32
z = 5.66.
I'm not 100% sure of the value of angle y but I think its
1/2(100 + 80) = 90 degrees.
I'll try and check that out.
Yes that is right.
Step-by-step explanation:
y=-1/2.x+2 =-2 then x=8
the area is S = 
S=121/4
