i did the other one but can someone help me with this one:
Four = fifths of the sum of a number and three is equal to six and a half. What is the number?
also ms. sue deleting my question was not very nice because it took me forever to type it and if you didn't know it then someone else couldve helped me...
Is that
(4/5)x + 3 = 6.5
or
(4/5)(x+3) = 6.5 ?
clarify.
oh i think i got the answer but thanks you so much :)
I apologize for any inconvenience caused. I'm here to assist you. Let's solve the math problem together.
To find the number, let's break down the given information:
"Four-fifths of the sum of a number and three": This means that we need to find the sum of a number and three, and then take four-fifths of that sum.
Let's assign a variable to the unknown number. We'll call it "x." Therefore, the sum of the number and three can be written as "x + 3."
Now, we can write the equation as follows:
(4/5)(x + 3) = 6.5
To solve this equation, we'll first multiply both sides by 5 to eliminate the fraction:
5 * (4/5)(x + 3) = 5 * 6.5
This simplifies to:
4(x + 3) = 32.5
Next, distribute the 4 to the terms inside the parentheses:
4x + 12 = 32.5
To isolate the variable, subtract 12 from both sides:
4x + 12 - 12 = 32.5 - 12
This gives us:
4x = 20.5
Finally, divide both sides by 4 to solve for x:
(4x)/4 = 20.5/4
Hence, the solution is:
x = 5.125
Therefore, the number is 5.125.
