the width of Jana's rectangular classroom is 1 meter more then 1/4 of its length. if the perimeter of the classroom is 24 meters

Bumek [7]

Let's call the length L, the width w.
We have w=1+L/4.
The perimeter is P=2(L+w)=24 hence L+w=12
L+w=L+(1+L/4)=5L/4+1=12
Hence L=11/5*4=8.8 meters

Ahhhh i need help again.

Answer:

B

Step-by-step explanation:

A. these simply to 21 + 7x and 21 + 3x

this one is incorrect because the 7x and 3x are different

B. these simplify to 10 + x and 10 + x

this is the correct one since they are exactly the same

C. these simplify to 21x and 7x + 21

these two are not the same because one expression has only a number with a variable but the other one has a number with a variable <em>and </em>another number

D. these simplify to $\frac{7}{3-x}$ and $\frac{7}{x-3}$

in subtraction, the order of the 3 and the x matters, so the equations are not the same
example: 6 - 4 = 2 but 4 - 6 = -2

The answer is C, (5,-2) if you graph all the other points you can easily see where the missing point should be considering it's a rectangle

Help help help help help math math please please pelsss

Answer:

Both of the angles will add up to 180 degrees so let’s make an equation.

5x-5+2x+10=180

First we collect like terms

5x+2x-5+10=180

Add them up

7x+5=180

Move the constant to the right

7x=180-5

7x=175

7x/7=175/7

x=25

So yes it’s true x=25.

Now we find the respective angles,

5x-5

5(25)-5

125-5

120

So angle one is 120 degrees.

2x+10

2(25)+10

50+10

60

So angle two is 60 degrees.

Now to check,

120+60=180
