Hi, I just need some help with algebra cause my teacher wont respond lol. SOOOO
Evaluate the following expression for
s = 4 and t = 8.
3st² ÷ st + 6
I can't seem to get the problem right and I've tried doing 3x4x8^2 divide 4x8 +6 but it doesnt equal what the answer key had and I also tried 348^2 divide 48 + 6 but that didn't equal it either so??
well s t is 32 not 48
(3 * 4 * 64)/(32) +6
3 *4 *2) + 6
24 + 6
30
still its not the same thing that she had on her answer key, the answer was 1542 and I have no idea how she got that
To evaluate the expression 3st² ÷ st + 6 for s = 4 and t = 8, let's break it down step by step.
First, substitute the values of s and t into the expression:
3st² ÷ st + 6
Replace s with 4 and t with 8:
3(4)(8²) ÷ (4)(8) + 6
Next, simplify the exponents:
3(4)(64) ÷ (4)(8) + 6
Multiply the numbers within parentheses:
3(256) ÷ 32 + 6
Now, perform the multiplication:
768 ÷ 32 + 6
Divide 768 by 32:
24 + 6
Add 24 and 6 together:
30
Therefore, the value of the expression with s = 4 and t = 8 is 30.
