Can you please help me on -5(-4r-6)=5(6-r)

Wewaii [24]

The answer you are looking for is no solution.

To find this, you first distribute the -5 into the parenthesis (-4r - 6). -5 x -4r = 20r and -5 x -6 = 30.Next, distribute the 5 into the parenthesis (6 - r). 5 x 6 = 30 and 5 x r = 5r.

The equation says 20r + 30 = 5r + 30. Now you solve for r.Subtract 5r from both sides. This leaves the equation to say 15r + 30 = 30. Then subtract 30 from both sides, to get 15r = 0.

At this point, since there is a zero on the opposite side of the variable, you can assume it will be no solution, since multiplying or dividing 0 by anything, is 0. However, I'll finish the problem, to show that it is no solution.

Divide 15 from both sides, leaving r = 0, which is no solution.

I hope this helps!

Measure of angle 7 = 2x+15<br> measure of angle 8 = 3x

lina2011 [118]

7 = 2x + 15

<7

Subtract by 15

-8 = 2x

Divide by 2

-4 = x

<8

8 = 3x

divide by 3

8/3 = x

Louann and Carla received equal scores on a test made up of multiple choice questions and an essay. Louann got 14 multiple choic

HACTEHA [7]

Hello,

x= number of points for each multiple choice question correct
L= Louann's score
C= Carla's score

Louann got 14 multiple choice questions correct and 24 points for her essay, so:

$L=14*x+24$

Carla got 16 multiple choice questions correct and 14 points for her essay, so:

$C=16*x+14$

But we know that they got the same score, then:

$L=C \\ 14x+24=16x+14 \\ 10=2x \\ \boxed{x=5}$

Answer: Each multiple choice question was 5 points

Find the volume of a cylinder with a radius of 3cm and a height of 7 cm.

svetoff [14.1K]

Answer:

The volume of the cylinder ≅ 197.82 $cm^{2}$

Step-by-step explanation:

The volume of a cylinder is equal to the area of the base times the height. We know the radius, therefore we can find the area of the base. The formula for the volume of the cylinder is as follows:

V = π $r^{2}$ $h$

(now substitute the values of "r" and "h", and get...)

V = π $r^{2}$ $h$

$V = (3^{2} )(7)$ x π

V = (9)(7)π

V = 63π

V ≅ 197.82 $cm^{2}$
