It would be 1/2 and in decimal form it’d be 0.5
To find this number, let's represent the unknown amount of students with the variable x:
356 + 365 + x = 977
721 + x = 977
x = 256
There are 256 students in ninth grade.
Answer:
Option B, x =
Step-by-step explanation:
e^4x-1 = 3
<u>ln both side</u>
ln(e^4x - 1) = ln(3)
<u>ln(e) = 1</u>
4x - 1 + 1 = ln(3) + 1
4x / 4 = (ln(3) + 1) / 4
x =
Answer: Option B, x =
Answer:
x=25.61
Step-by-step explanation:
To determine the smallest amount, in dollars , that you can charge and make a profit of atleast $415, you need to find the value of x that gives p=415.
Substitute p=415 in the given quadratic equation and solve it for x.
on solving we get
The smallest amount you could charge and make a profit of $415 is $25.61
Answer: -4
Step-by-step explanation: Don't knw if this will help but sometimes use a number line. Place the positive first then negative. search on google on how to do it.
