How do you answer this equation? 5a - 12 = 48

IgorC [24]

Add 12 to both sides resulting in 5a = 60 and then divide both sides by 5 which results in a = 12 so your answer will be a = 12

Is the m in mx+b=y the growth

Shalnov [3]

The "m" in y = mx + b is the slope.

It is the number of units a point goes up, down, left, or right each time. Making the line linear/straight.

$m = \frac{rise}{run}$

"rise" is the the number of units you go up(+) or down(-), "run" is the number of units you go to the right

For example, if your slope is:

$\frac{1}{2}$

You are going up 1 unit, and to the right 2 units

3 or $\frac{3}{1}$

You are going up 3 units, and to the right 1 unit

$-\frac{1}{2}$

You are going down one unit, and to the right 2 units

-3 or $-\frac{3}{1}$

You are going down 3 units, and to the right 1 unit

This trapezium is drawn on a centimetre grid. Find the area of the trapezium.

aivan3 [116]

Answer:

20 unit²

Step-by-step explanation:

A trapezium is given to us on the grid and we need to find out the area of the trapezium . In order to find the area , we need to find the measure of the parallel sides and the distance between the parallel sides.

From the grid :-

$\rm\implies Side_1 = 7 \ units$

$\rm\implies Side_2 = 3 \ units$

$\rm\implies \perp \ Distance =4 \ units$

Now here we got the two parallel sides of the trapezium and the distance between the two parallel sides. Now we can find the area as ,

$\rm\implies Area_{Trapezium}= \dfrac{1}{2}\times ( s_1 + s_2) \times \perp \ Distance \\\\\rm\implies Area = \dfrac{1}{2} \times ( 7 + 3 ) \times 4 \ unit^2 \\\\\rm\implies Area = \dfrac{1}{2} \times ( 10) \times 4 \ unit^2 \\\\\rm\implies\boxed{\rm Area = 20 \ unit^2}$
