There are 14 girls in class five.
<h3>How many of the students are girls?</h3>
28 students were present in class five, such that 18 of them were boys.
The number of girls on Sunday is given by the difference:
28 - 18 = 10
And we know that 4 girls did not go to school on that day, so the total number of girls on class five is:
10 + 4 = 14

Answer:
The answer is correct x =6.8, if she made an error, it might have been the steps she took.
Step-by-step explanation:
5.4 + x = 12.2
subtract 5.4 from both sides to put x terms on the left hand side, numerical number terms on the right hand side
5.4 - 5.4 + x = 12.2 - 5.4
x = 6.8
x3 - 1/2x + 2 = 0
if you mean x³, and not x3, then heres the answer to the problem: (if it is something else please let me know)
x³ - 1/2x + 2 = 0
-2 -2
x³ - 1/2x = -2
^no side is 0 :D
-10(1-9x) +6(x-10)
-10+90x+6x-60
96x-70
so d is the answer
Answer:
-1
Step-by-step explanation:
Tip: Remember to always start from the inside, which would be g(3), in this case.
The first step in solving this problem is to solve for g(3).
To accomplish this, you must substitute 3 for x into the given equation g(x) = x^2 - 10
- g(3) = 3^2 - 10
- g(3) = 9 - 10
- g(3) = -1
The next step is to substitute the answer of g(3), -1, for x in the given equation f(x) = 2x + 1.
Because the equation is asking for f[g(3)], it becomes f(-1) because g(3) = -1.
- f(-1) = 2(-1) + 1
- f(-1) = -2 + 1
- f(-1) = -1
Therefore, f[g(3)], or f(-1), equals -1
