36+3(4x-9)=c(2x+1)+25\\\\36+12x-27=2cx+c+25\\\\9+12x=2cx+c+25\ \ \ |-9\\\\12x=2cx+c+16\ \ \ |-2cx\\\\12x-2cx=c+16

The equation has no solution. Therefore, x must be eliminated. Then the equation will not make sense if the left side is not equal to the right side (different numbers).

12x-2cx=0\to 12-2c=0\to c=6

Substitute the value of c to the equation and check it:

12x-2(6)x=6+16\\\\12x-12x=22\\\\0=22\ FALSE

Answer: C) 6

First, it would help to simplify each side more:

Left side: 36 + 3(4x - 9) = 36 + 12x - 27 = 12x + 9

Right side: c(2x + 1) + 25 = 2cx + c + 25

Write the simplified equation:

12x + 9 = 2cx + c + 25

Usually when there is no solution, the coefficients of the variable on both sides are the same, so we can make the coefficient if x on the right side into 12:

2cx >>> 12x

Then, c must equal 6 to make this true.

The answer is choice (C).

I need help with this last question.

Answer:

Step-by-step explanation:

length=1 m

base of triangle=10 m

height=5m

volume= 1/2×10×5×1=25 m cube.

slant height l=√(5²+5²)=√50=5√2

slant surface area=2[5√2×1]=10√2

area of front and back=2×1/2(10×5)=50

total surface area=50+10√2≈50+14.14≈64.14 m²

Answer:

  y +1 = -3(x -3)

Step-by-step explanation:

The given point is (3, -1), and the given slope is -3. The form suggests you want the point-slope form of the equation for the line:

  y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

Using the given values, the equation is ...

  y -(-1) = -3(x -3)

  y +1 = -3(x -3)

The length of a classroom is 34 feet. What is this measurement in yards and feet? A 17 yards 0 feet B 11 yards 1 foot C 8 yards
laila [671]
1 yard = 3 feet

Divide 34 by 3, you should get 11 and 1/3.
So the classroom is 11 1/3 yards long, but 1/3 of a yard just so happens to be one foot, as 3 feet is 1 yard.

That means that the classroom is 11 yards and 1 foot long, or answer choice B.

Hope this helps! :)
