In what year was her grandpa lopez twice as old as her dad?show how you know
RoseWind [281]
So,

We are trying to figure out when Grandpa Lopez's age was twice that of Dad.

Let x represent the number of years before/after when G. Lopez's age was twice that of Dad.

66 + x = 2(37 + x)

Distribute.
66 + x = 74 + 2x

Subtract x from both sides.
66 = 74 + x

Subtract 74 from both sides.
-8 = x

So 8 years ago, G. Lopez was twice as old as Dad.  Let's check that.

66 - 8 = 58

37 = 8 = 29

29 * 2 = 58
58 = 58

It checks.

Given the function g(x) = (5 - x)^3 , what is the value of g(2)?
11111nata11111 [884]

Answer:

g(2) = 27 is the answer.

Step-by-step explanation:

If the function is g(x) = (5 - x)³

By expanding (5 - x)³ = 5³-3.5²x + 15x² -x³

g(x) = 125 - 75x + 15x² - x³

Now g(2) = 125 - 75×2 + 15×(2)² - 2³

        g(2) = 125 - 150 + 60 - 8

               = -25 + 60 - 8

              = 35 - 8 = 27

Or directly putting the value x = 2 in g(x) we get

g(2) = (5 - 2)³ = 3³ = 27

Therefore g(2) = 27 is the answer.

What is the probability of spinning green?
professor190 [17]
0.25 because there is 4 colours and obviously red is 0.75 percent and green and blue can’t be lower than 0.5 cuz that’s for yellow and there’s no 0%

(That makes no sense but it’s 0.25%)
