and if that line is diagonal then we know A is equal to B'
so B is equal to 90-55 = 35

What value of m makes the equation 5/2(4m-8)- 2(6m -7)= -10 true?

Dmitrij [34]

$\dfrac{5}{2}(4m-8)- 2(6m -7)= -10\\\\\\\dfrac{5\cdot4}{2}m-\dfrac{5\cdot8}{2}- 2\cdot6m -2\cdot(-7)= -10\\\\\\\dfrac{20}{2}m-\dfrac{40}{2}-12m+14=-10\\\\\\10m-20-12m+14=-10\\\\-2m-6=-10\quad|\cdot(-1)\\\\2m+6=10\\\\2m=10-6\\\\2m=4\quad|:2\\\\\boxed{m=2}$

The correct option is: A. 80 cm³

Explanation

Diameter of the coin, $d= 2.0$ cm.

So, the radius, $r= \frac{d}{2} = \frac{2.0}{2} = 1.0$ cm.

As the coin is circular, so..

Area of each circular surface, $A= \pi r^2 = \pi (1.0)^2 = \pi$ cm²

Now for finding the amount of plastic for making each coin, we will find the Volume of each coin first.

As the thickness ( $h$ ) of the coin is 0.5 cm, so Volume of each coin,

$V= A*h \\\\= \pi*0.5 \\\\= 3.14159... * 0.5 \\\\ = 1.5707963... cm^3$

As you need to make a batch of 50 coins, so the total volume of 50 coins $= (1.5707963...*50 )= 78.53981... = 80$ [Rounded up to the nearest multiple of 10 cm³]

So, the amount of plastic you will need for making a batch of 50 coins is 80 cubic centimeter.

-2/3 x -9/8 x -4/5 x -1

Lerok [7]

Answer: 0.6

Step-by-step explanation: First, you want so seperate the equations in parenthesis to make solving the equation easier.

(-2/3x-9/8x )-(4/5x)-(1)

So (-2/3x-9/8x) equals -11/24x

And -11/24x-4/5x equals -151/120x

So -151/120x-1 ends up being 0.6.
