Call x Andrew's age.

Then, Carol is 3 times older => Carol's age is 3x

And, Brad is 2 year older than Andrew => Brad's ages x + 2

In six years, Carol's age will be 3x + 6, Brad's age will be x + 2 + 6 and Andrew's age will be x + 6

Then, the sum of Andrew's and Brad's ages in six years will be:

(x + 6)+ (x + 2 + 6) = 3x + 6

Now, you can solve the equation:

x + 6 + x + 8 = 3x + 6

=> 3x - x - x = 8

=> x = 8.

So, today Carol's age = 3x = 3(8) = 24.

Answer: 24 years

What is the equation for the line with a slope of - 2/3 that passes through (0, -2)
viktelen [127]

Answer:

y= -2/3x-2

Step-by-step explanation:

Since we have a point and a slope, we can use the point slope formula

y-y_{1} =m(x-x_{1})

m is the slope. In this case, m is -2/3

y1 is the y coordinate of the point. In this case, it is -2

x1 is the x coordinate. In this case it is 0.

We can substitute these values into the formula

y- -2= -2/3(x-0)

Distribute -2/3

y+2 = -2/3*x + -2/3*0

y+2= -2/3x+0

Subtract 2 from both sides. We want to get y by itself. This is because we want our line to be in y=mx+b form.

y+2-2= -2/3x+0-2

y= -2/3x -2

Find 3 consecutive odd integers whose sum is 225, explain please
aleksklad [387]
3 odd integers have a property that they average up to the middle large one. Let's say we have 3, 5, and 7. 3 is 2 less than 5 and 7 is 2 more than 5. so when you add them it equals 2 times 5. 
After we know that, the sum of 3 odd integers is just 3 times the middle number. ex. 3+5+7 = 3 times 5 = 15
Then we know the some number times three = 225. we find out that the middle number is 75, so the other two are 73 and 77
