Answer:
turn it into an equation
since the total number of students is 63 and for every 3 boys are 4 girls
3x + 4x = 63
7x = 63
x = 63/7
x= 9
to get the number of boys
3 x 9 = 27
therefore the number of boys is 27

Answer:
45 units squared
Step-by-step explanation:
Basically you know that two parts of the square is equal to a whole, as 50 plus 50 is 100.
So on the left diagonal, it is equal to 3 units squared, since there are 6 parts and each unit diagonal is equal to 1/2 of a square.
On the right side, there are also 3 units squared, since there are 6 parts and blah blah blah.
Even if it looks different, two partial squares will still add up to one whole square. So the diagonals are equal to 6 units.
Then you can add up your full squares that you already know of so there are 9 units on the bottom row and another 9 on top.
Then you add 7 for the third layer and 6 more on the next.
There are 4 on the next layer and 3 and another square.
So 9 + 9 + 7 + 6 + 4+ 3 + 1.
That is 39.
But you may say: BUT WAIT SCOTTY THERE IS ANOTHER 6
me: oh yah i frgot bro thanks m8
So since there is another 6 more units, it is 45 since 39 + 6 is 45.
Hope this helps boi

to solve for the sine you have to look at the hypotenuse aka the opposite side.
Sorry I cannot solve for the Sin, I am a child of God, a brother to Jesus. I do not believe in sins, since I have never sinned in my life. I have been enlightened from the gods themselves. They taught me right from wrong and wrong from right. Anybody can be forgiven for their sins, such as now. Your sins are now forgiven by a higher being.

solve for x and y graphically, 2y= 3x+1 and y=2x+3
Answer:
[tex](-\frac{1}{3},\frac{1}{2} )[/tex] , [tex](-\frac{3}{2} ,3)[/tex]
Step-by-step explanation:
2y = 3x + 1
y = 2x + 3
Graph 2y = 3x + 1.
Divide each term by 2 and simplify.
[tex]y=\frac{3x}{2}+\frac{1}{2}[/tex]
Rewrite in slope-intercept form.
[tex]y=\frac{3}{2}x+\frac{1}{2}[/tex]
Use the slope-intercept form to find the slope and y-intercept.
Find the values of m and b using the form y = mx + b.
[tex]m=\frac{3}{2}[/tex]
[tex]b=\frac{1}{2}[/tex]
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: [tex]\frac{3}{2}[/tex]
y-intercept: [tex](0,\frac{1}{2} )[/tex]
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
Find the x-intercept.
x-intercept(s): [tex](-\frac{3}{2},0 )[/tex]
y-intercept(s): (0, 3)
Create a table of the x and y values.
_x_|_y_
[tex]-\frac{3}{2}[/tex] | [tex]0[/tex]
[tex]0[/tex] | [tex]3[/tex]
Graph the line using the slope and the y-intercept, or the points.
Slope: 2
intercept: (0, 3)
_x_|_y_
[tex]-\frac{3}{2}[/tex] | [tex]0[/tex]
[tex]0[/tex] | [tex]3[/tex]
Graph y = 2x + 3
Use the slope-intercept form to find the slope and y-intercept.
Slope: 2
intercept: (0, 3)
x-intercept(s): [tex](-\frac{3}{2},0)[/tex]
y-intercept(s): (0, 3)

300x + 6,250=10,000
Answer:
x= 25 /2 and/or 12.5
Step-by-step explanation:
Let's solve your equation step-by-step.
300x+6250=10000
Step 1: Subtract 6250 from both sides.
300x+6250−6250=10000−6250
300x=3750
Step 2: Divide both sides by 300.
300x /300 = 3750 /300
x= 25 /2
Answer: X is 3450

Answer:
100 3/10, 1003/10, or 100.3
Step-by-step explanation:
Converting your word to numbers, we have the equation:
x = 100 + 3/10
We could automatically leave it as a mixed number. Or, if you want to get a bit more complicated, you could turn it into an improper fraction or decimal:
1003/10 or 100.3
Answer:100.3
