Problems are very often written in a confusing way. This one couldn't possibly have been
written any more clearly. Sooner or later, you have to stop telling yourself that you have
no clue, settle down, and carefully read the words that are right there on the page.
I'll tell you one more detail that's not in the problem: "breadth" means "width".
Now. The problem clearly tells you all of these things, in this exact order:
=> Area of the walls = (2 x height) x (length + width)
=> length = 8m
=> width = 6m
=> height = 2.5m
Is there a reason you can't take the numbers for length, width, and height,
and write them in the formula for the area ? Do I have to do all the work ?
Area = (2 x height) x (length + width)
Area = (2 x 2.5m ) x ( 8m + 6m )
Do the arithmetic inside the parentheses:
Area = ( 5m ) x ( 14m )
Do the multiplication:
Area = <u>70 m² .</u>
You will never see a problem that comes any closer to answering itself <em>for </em>you.
Weight of one large bead is 1.5 grams and weight of one small bead is 8.75 grams.
Step-by-step explanation:
Let,
Weight of one large bead = x
Weight of one small bead = y
According to given statement;
12x+8y=88 Eqn 1
5x+2y=25 Eqn 2
Multiplying Eqn 2 by 4
![4(5x+2y=25)\\20x+8y=100\ \ \ Eqn\ 3\\](https://tex.z-dn.net/?f=4%285x%2B2y%3D25%29%5C%5C20x%2B8y%3D100%5C%20%5C%20%5C%20Eqn%5C%203%5C%5C)
Subtracting Eqn 1 from Eqn 3
![(20x+8y)-(12x+8y)=100-88\\20x+8y-12x-8y=12\\8x=12](https://tex.z-dn.net/?f=%2820x%2B8y%29-%2812x%2B8y%29%3D100-88%5C%5C20x%2B8y-12x-8y%3D12%5C%5C8x%3D12)
Dividing both sides by 8
![\frac{8x}{8}=\frac{12}{8}\\x=1.5](https://tex.z-dn.net/?f=%5Cfrac%7B8x%7D%7B8%7D%3D%5Cfrac%7B12%7D%7B8%7D%5C%5Cx%3D1.5)
Putting x=1.5 in Eqn 1
![12(1.5)+8y=88\\18+8y=88\\8y=88-18\\8y=70](https://tex.z-dn.net/?f=12%281.5%29%2B8y%3D88%5C%5C18%2B8y%3D88%5C%5C8y%3D88-18%5C%5C8y%3D70)
Dividing both sides by 8
![\frac{8y}{8}=\frac{70}{8}\\y=8.75](https://tex.z-dn.net/?f=%5Cfrac%7B8y%7D%7B8%7D%3D%5Cfrac%7B70%7D%7B8%7D%5C%5Cy%3D8.75)
Weight of one large bead is 1.5 grams and weight of one small bead is 8.75 grams.

Answer:
y= 2x + (-2)
Step-by-step explanation:
The algebraic formula y=mx+b can be broken down into mx, equaling slope +x, and b, which is the y intercept. Taking two points from the slope, you can see that the slope is 2, as the line moves up 2 on the y axis for every 1 move horizontally on the x axis. Additionally, we see that this particular line crosses the y axis at the point (-2), meaning that is the y intercept. Hope this can offer some assistance.
