Number of girls at the time of the assembly started = w
Number of girls left = 40% of w
Remaining girls = 
Now, the ratio of the number of boys to girls became 3 to 4.
Let n be the number of boys.
Then, 
Or, 
20n = 9w
or, n = 
Total number of boys and girls = 
Hence, the total number of boys and girs is 
Answer:
y = 10
Step-by-step explanation:
2y - 5 = 15
make y the subject of the formula
2y = 15 + 5
2y = 20
y = 20/2
y = 10
Answer:
Step-by-step explanation:
Domain of the function will be,
{x ∈ R | x ≠ -2}
Range of the function is,
{y ∈ R | y ≠ -4}
Intercepts of the function,
Their are no intercepts of the given rational function.
Horizontal asymptotes:
Horizontal line parallel to x-axis representing discontinuity.
y = -4
Vertical asymptotes:
Vertical line parallel to y-axis representing discontinuity.
x = -2
No oblique asymptotes.
Answer:
t < 1/2
Step-by-step explanation:
Isolate the <u>v</u><u>a</u><u>r</u><u>i</u><u>a</u><u>b</u><u>l</u><u>e</u> by dividing each side by <u>f</u><u>a</u><u>c</u><u>t</u><u>o</u><u>r</u><u>s</u> that don't contain the <u>v</u><u>a</u><u>r</u><u>i</u><u>a</u><u>b</u><u>l</u><u>e</u>.
Inequality Form: t < 1/2
Interval Notation: ( -infinity, 1/2)
