Answer: 69
Step-by-step explanation: Percent multiplied by the total number of students: 8/100 x 75 = 600/100. (remember it is 8/100 because it’s 8%.)
Then you simplify which will then get you 6.
Afterwards you need to subtract those 6 students from the group of 75. 75-6=69. So, 69 students.
In math for we have:
2x-2=x+64
which turns into:
x=66
(subtract x from right) & (add two from left)
Answer:
−8^4+2^3−4^2+6
Step-by-step explanation:
Distribute the - to 8x^4-5x^3+6x^2-2x:
-8x^4+5x^3-6x^2+2x
Now simplify:
-3x^3+2x^2+4x-8x^4+5x^3-6x^2+2x= −8^4+2^3−4^2+6
Hope this helps!
