Can you help me to slove this?
its 30
No, the answer is 38. Learn your math. LOL just kidding, it IS 30 correct 100% true
How to do the expression, ma'am
Okay.....what do I do next?
correct
Sure! To evaluate the expression for x = 3 3/4, we need to substitute the value of x into the expression and simplify it.
First, let's convert the mixed number 3 3/4 into an improper fraction.
To do this, multiply the whole number (3) by the denominator (4) and add the numerator (3). This gives us (3 * 4) + 3 = 12 + 3 = 15. So x = 15/4.
Now, substitute this value into the expression 8x + 8:
8 * (15/4) + 8
To simplify, multiply the 8 by both the numerator and denominator:
(8 * 15) / 4 + 8
The numerator becomes 120 and the denominator remains as 4:
120/4 + 8
Simplifying further, divide the numerator by the denominator:
30 + 8
Finally, add:
30 + 8 = 38.
Therefore, the value of the expression for x = 3 3/4 is 38.
So, the correct answer is D) 38.
8x+8 =
Substitute 3 3/4 for x. You could change 3 3/4 to 3.75.
