In the given question there is an equation that has to be solved and the value of the unknown variable "M" has to be determined. It is absolutely possible to find the exact value of the variable "M" as there is 1 equation and 1 variable.
302 + 12 M = 278
12 M = 278 - 302
12 M = - 24
M = - (24/12)
   = - 2
So the value of the unknown variable "M" comes out to be -2. I hope the procedure is clear enough for you to understand and also this is the answer you were looking forward to.

If you would like to solve 302 + 12 * M equals 278, you can calculate this using the following steps:

302 + 12 * M equals 278
302 + 12 * M = 278        /-302
12 * M = 278 - 302
12 * M = - 24                  /12
M = - 24 / 12
M = - 2

The correct result would be - 2.

2 cm green square is painted on a triangle with a base of 6 and a height of 7. A dot will be randomly placed on the triangle. Wh
agasfer [191]
The area of the triangle is
(1/2)*(6)*(7) = 21 cm²

The area of the square is
(2)(2) = 4 cm²

The area of the triangle that is not covered by the square is
21 - 4 = 17 cm²

The probability that the dot will be placed outside the square is
17/21 

Answer: 17/21 (or 0.81)

sin(-\theta )\implies -sin(\theta )\qquad \qquad cos(-\theta )\implies cos(\theta )

In rectangle ABCD, AC = -x + 21, BP = -9x + 19, and DP = -y + 5. Find the value of y.
creativ13 [48]

Answer:

y=-5

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The diagonals of a rectangle are equal and bisect each other

so

BP=\frac{1}{2}AC

DP=BP

step 1

Find the value of x

BP=\frac{1}{2}AC

substitute the given values

(-9x+19)=\frac{1}{2} (-x+21)

solve for x

Multiply by 2 both sides

-18x+38=-x+21

18x-x=38-21\\17x=17\\x=1

step 2

Find the value of y

DP=BP

we have

BP=-9x+19

DP=-y+5

substitute

-y+5=-9x+19

substitute the value of x

-y+5=-9(1)+19\\-y+5=10\\y=5-10\\y=-5
