Valerie tells Robbie, "I'm thinking of a number between 1 and 50. If I divide the number by 4, then add 5, then subtract 6, I get 6. i tried 12,24,36,48,42
its non of those
28
Valerie tells Robbie I’m thinking of a number between 1 and 50 if I divide the number by 4 then add 5 then subtract 6 I get 6 what number is Valerie thinking of
whats the answer?
your number ---- x
x/4 + 5 - 6 = 6
x/4 = 7
multiply both sides by 7
x = 28
try it.
wilma tells betty im thinking of a number 1 and 10 if i take the number and add 4 to it then multiply that by 3 i get 30
28
To find the number Valerie is thinking of, you can follow the steps she stated and solve for the unknown number. Let's break it down:
1. Divide the unknown number by 4.
Let's call the unknown number "x". So, the first step is x/4.
2. Add 5 to the result from step 1.
This gives us (x/4) + 5.
3. Subtract 6 from the result in step 2.
The equation becomes (x/4) + 5 - 6.
According to Valerie, this expression equals 6. To solve for x, we can set up the equation:
(x/4) + 5 - 6 = 6.
Now, let's solve for x:
First, let's simplify the equation by combining like terms:
(x/4) - 1 = 6.
Next, let's isolate the x-term by adding 1 to both sides of the equation:
(x/4) = 6 + 1,
(x/4) = 7.
To get rid of the fraction, we can multiply both sides of the equation by 4:
4(x/4) = 4(7),
x = 28.
So, Valerie's number is 28.
