So since we know what x is, we can substitute it into the original equation for x like so to solve for y...
(2y - 8) + 5y - 10 = 0
2y - 8 + 5y = 10
2y + 5y = 18
7y = 18
y = 18/7 (or about 2.57)
So now we know what x is, we can sub it into the below equation to solve for x...
x = 2(18/7) - 8
x = 36/14 - 8 (or about -5.43)
K = Kevin's age
D = Daniel's age
K = 3D
K - 4 = 5(D - 4)
Plug in 3D for the K values in the second equation.
3D - 4 = 5(D - 4) Use the Distributive Property
3D - 4 = 5D - 20 Add 4 to both sides
3D = 5D - 16 Subtract 5D from both sides
-2D = -16 Divide both sides by -2
D = 8
Now, plug that D value into the original equation.
K = 3D Plug in the D value
K = 3(8) Multiply
K = 24
Finally, you can double check your math.
4 years ago, Daniel would've been 4 and Kevin would be 20, so Kevin would've been 5 times as old as Daniel. And 8 x 3 = 24.
So, Kevin is 24.
Answer:
It would be selected 130 times.
Step-by-step explanation:
peach chew was selected 13 times out of 60, so 13/60 will be peach
multiply the amount by 600, 13/60 * 600 = 130
The correct option is: B. 450
<u><em>Explanation</em></u>
Current value of the investment is 
dollars and 30 years ago, the value of the investment was 
dollars.
Suppose, the value of investment today is 
times greater than the value of the investment thirty years ago.
So, the equation will be........
Thus, the value of the investment today is 450 times greater than the value of the investment thirty years ago.
