because the bigger the bottom or left number is the smaller the value unless t was like 10/10 that's bigger than them all
2x + 8 = 44
2x = 36
x = 18
There are 18 boys, and 26 girls

This the answer
If f(x) = 3x - 1 and g(x) = x + 2, find (f- g)(x).
PLZZ HELPPP
2x-3
Answer:
Simplifying
5(2x + 6) = -4(-5 + -2x) + 3x
Reorder the terms:
5(6 + 2x) = -4(-5 + -2x) + 3x
(6 * 5 + 2x * 5) = -4(-5 + -2x) + 3x
(30 + 10x) = -4(-5 + -2x) + 3x
30 + 10x = (-5 * -4 + -2x * -4) + 3x
30 + 10x = (20 + 8x) + 3x
Combine like terms: 8x + 3x = 11x
30 + 10x = 20 + 11x
Solving
30 + 10x = 20 + 11x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-11x' to each side of the equation.
30 + 10x + -11x = 20 + 11x + -11x
Combine like terms: 10x + -11x = -1x
30 + -1x = 20 + 11x + -11x
Combine like terms: 11x + -11x = 0
30 + -1x = 20 + 0
30 + -1x = 20
Add '-30' to each side of the equation.
30 + -30 + -1x = 20 + -30
Combine like terms: 30 + -30 = 0
0 + -1x = 20 + -30
-1x = 20 + -30
Combine like terms: 20 + -30 = -10
-1x = -10
Divide each side by '-1'.
x = 10
Simplifying
x = 10
The Riemann sum with n = 6, taking the sample points to be midpoints is - 12.0625
<h3>What is Riemann sum?</h3>
Formula for midpoints is given as;
M = ∑0^n-1f((xk + xk + 1)/2) × Δx;
From the information given, we have the following parameters
Let' s find the parameters
Δx = (3 - 0)/6 = 0.5
xk = x0 + kΔx = 0.5k
xk+1 = x0 + (k +1)Δx
Substitute the values
= 0 + 0.5(k +1) = 0.5k - 0.5;(xk + xk+1)/2
We then have;
= (0.5k + 0.5k + 05.)/2
= 0.5k + 0.25.
Now f(x) = 2x^2 - 7
Let's find f((xk + xk+1)/2)
Substitute the value of (xk + xk+1)/2)
= f(0.5k+ 0.25)
= 2(0.5k + 0.25)2 - 7
Put values into formula for midpoint
M = ∑05[(0.5k + 0.25)2 - 7] × 0.5.
To evaluate this sum, use command SUM(SEQ) from List menu.
M = - 12.0625
A Riemann sum represents an approximation of a region's area from addition of the areas of multiple simplified slices of the region.
Thus, the Riemann sum with n = 6, taking the sample points to be midpoints is - 12.0625
