Answer:
C
Step-by-step explanation:
They are all integers so they are rational numbers, they are whole numbers as well except there are negative numbers so they are not all natural.
{ 8, -6 } as you multiply the first equation with 1.25 to get :
then, you use elemination by substraction to get rid of x:
try to solve for y to get y = -6, and then you use either equation 1 or 2 to find the value of x, which in both cases is equal to 8.
So I have 2 answers here they are.
key: 1/3hours =20 min
221÷2=110.5÷20=5.525
221.5÷20=11.075
I hope this helps!
Answer:
X = 40 degree
Step-by-step explanation:
First I would name the points whatever you do always name the points it really helps
So,
75 = a
50 = b
The middle point will be o
85 = c
X = d
Ok so,
Angle aob = y
Angle cod = z
Now,
75+50+y=180 (angle sum property)
y=180-125
y=55
Angle y = z (vertically opposite angles)
55+85+x=180 ( angle sum property )
x=180-140
Therefore x=40 degree
In higher classes you will be able to do this in your mind itself without calculation all you need is practice.
