Adding both equations cancels y:
<span>4x + 8y = 16
</span><span>4x - 8y = 0
-----------------+
8x = 16 => x=2
filling in x=2 in the first equation gives:
4*2 + 8y = 16 => 8y = 8 => y=1
So (2,1) is the (x,y) pair that solves the two equations. Answer C.</span>
Answer:
=900000
Step-by-step explanation:
the current ppl=225000
after 64 years=225000×2=450000
in the next 64 yrs(128 yrs later)=450000×2=900000
B is the answer because 12 divided by 6 is 2 and 18 divided by 6 is 3
Answer:
is D i had this on my math test
Step-by-step explanation:
Answer:
The largest possible value for the third side is 18.
Step-by-step explanation:
Here, the first side of the triangle = 17
Second side of the triangle = 2
Let us assume the third side of the triangle = m
Now, In any given triangle:
"Sum of any two sides of a triangle is strictly greater than the third side."
⇒ Sum of first side + Sum of second side > Third Side
or, m < 17 + 2
or, m < 19
hence, the largest possible value for m = 18
