Let us set up the equation using the given information
Boys = x
Girls = √x
Boys + girls = 42
Equation: x + √x = 42
You can now work out this equation to solve for x, OR reason your way through it. By substituting numbers into the equation. Try 36
36 + √36 = 42
36 + 6 = 42
42 = 42
ANSWER: 36 Boys (and 6 girls)
Hope this helps! God bless!! :)
1/8 .All you have to do is divide 1/4 by two and you get 1/8. If you want a decimal it would be 0.125
Answer:
The group with 36 people need more boats.
Step-by-step explanation:
36 divided by 5 = 7.2 (round up because you can't have 7.2 boats) 8 boats
24 divided by 4 = 6 boats
A. 41 ... bye using the properties of isosceles triangle
Answer:
a. (4, –7) and (0, –3)
Step-by-step explanation:
Easiest is to check the answer choices.
The constant in the first equation is -3, so we know that (0, -3) is a point on that graph. The sum of those two values is -3, so that is also a point on the graph of the line.
The only two answer choices with (0, -3) as one point are the first and last. The other point in the last answer choice is not on the line (4+7 ≠ -3).
So, the only viable answer choice is the first one.
_____
To solve the system algebraically, you can substitute the expression for y in the first equation into the second equation:
x + (-x^2 +3x -3) = -3
-x^2 +4x = 0 . . . . . . . . . add 3
-x(x -4) = 0 . . . . . . . . . . factor
Solutions are x = 0, x = 4. (These are the values of x that make the factors 0.)

Evaluating the second equation to find y is easiest:
y = -3 -x
For x=0, y = -3.
For x=4, y = -7.
The solutions are (4, -7) and (0, -3).
