Your brother is now 11. If your brother is 3, you put '8+x'=x+5 to get your cousins age. Once you have x+5, set it equal to 2(x-3) and solve that. You should get x+5=2x-6 and you get x=11. You add 8 to get your cousins age. So your brother is 11 and your cousin is 19.

Answer:
11
Step-by-step explanation:
Put 3 where x is and do the arithmetic.
g(x) = x² +2
g(3) = 3² +2 = 9+2
g(3) = 11
(2/3)*((2/3)*m-(2/3)) = 0
(2/3)*((2/3)*m-2/3) = 0
2/3*(2/3*m-2/3) = 0
2/3*m-2/3 = 0 // + 2/3
2/3*m = 2/3 // : 2/3
m = 2/3/2/3
m = 1
Answer: 5485
Step-by-step explanation: 16000:4= 4000
4000:10= 400
400x3= 1200
1200:21 = 57
57x5= 285
Answer:
Say you have y=2x. That is direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2x to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.
