Answer:
Jay has 8 computer games
Step-by-step explanation:
Let
x -----> the number of computer games Sherry has
y -----> the number of computer games Jay has
z -----> the number of computer games Nairan has
we know that
----> equation A
----> equation B
----> equation C
Substitute equation A and equation B in equation C and solve for y
therefore
Jay has 8 computer games
Answer:
20*30=600
This could be written out with addition instead, as 20 'times' 30
30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30
=600
Answer:
5/6
Step-by-step explanation:
1/2 + 1/4 + 1/12 =
The LCD is 12.
= 6/12 + 3/12 + 1/12
= 10/12
= 5/6
To determine the effect of the radius changes to the coefficients, we need to rewrite the form of the equation into:
(x−α)²+(y−β)²=r²
From the equation, we will see that:
C=−α∗2
D=−β∗2
and α²+β²−r²=E
where r represents the radius of the circle and α,βare the coordinate of the center of the circle.
Therefore, when the r decreases the coefficients C and D do not change but E increases.
