Answer: gabriel
Step-by-step explanation: when you have x and y,, they usually are equal to 1 and with gabriel's expression,, he made it simplier for us to solve but with his sister,, she just made it more different though both expressions are right,, but in the end gabriel is correct
Answer:
C
Step-by-step explanation:
a=
r^2
To find the radius, divide the diameter by 2
r=d/2
r=10/2
r=5
a=r^2
a=5^2
a=25
So, choice C is correct
Hope this helps! :)
Answer:
1.17
Step-by-step explanation:
5-(2.18+1.65)
Answer:
1. 3
2. 2
3. 2
4. 6
5. No solution
Step-by-step explanation:
2x+3y=8 (1)
-6x+4y=11 (2)
3(1) + (2)
6x + 9y = 24
-6x + 4y = 11
13y = 35
y = 35/13
x = -1/26
3x-y=3 (1)
-2x+2y=6 (2)
2(1) + (2)
6x - 2y = 6
-2x + 2y = 6
4x = 12
x = 3
y = 3(3) - 3 = 6
3x+4y=-10 (1)
5x-2y=18 (2)
(1) + 2(2)
3x + 4y = -10
10x - 4y = 36
13x = 26
x = 2
5x-2y=3 (1)
2x-y=0 (2)
(1) - 2(2)
5x - 2y = 3
-4x + 2y = 0
x = 3
2(3) - y = 0
y = 6
3x+2y=10 (1)
6x+4y=14 (2)
2(1) - (2)
6x + 4y = 20
6x + 4y = 14
0 = 6 is a false statement so no solution
