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!

Answer:

  • x = 30°
  • DB = 26
  • AD = BC = AB = DC = 7

Step-by-step explanation:

  • <em>Diagonals of a square are congruent and perpendicular and bisect each other</em>
<h3>Q4</h3>

m∠AEB = 3x

m∠AEB = 90°

  • 3x = 90° ⇒ x = 30°
<h3>Q5</h3>

AE = 3x - 2

EC = 2x + 3

  • AE = EC
  • 3x - 2 = 2x + 3
  • 3x - 2x = 3 + 2
  • x = 5

DB = EC = 2(AE) = 2(3*5 - 2) = 2(13) = 26

<h3>Q6</h3>

<u>AD and BC are the sides, which are equal</u>

  • 2x - 1 = 5x - 13
  • 5x - 2x = 13 - 1
  • 3x = 12
  • x = 4

AD = BC = AB = DC =  2*4 - 1 = 7

A rectangular piece of sheet metal is 4 ft longer than it is wide. (see the illustration.) the area of the piece of sheet metal
pshichka [43]
This is the start to the approach that would be taken to get both variables in terms of only one so it can be solved but since the numbers are so small you could easily test out numbers and figure out that it's 6 and 10 feet.

length = width + 4

length * width = 60
(width + 4) * width = 60

Write an exponential function in the form y=ab^xy=ab
ivanzaharov [21]

Answer:

Step-by-step explanation:

let y=ab^x

x=0,y=18

18=ab^0=a

a=18

y=18b^x

when x=2,y=1152

1152=18b^{2}\\b^{2}=\frac{1152}{18}=64=8^2\\b=8\\so~y=18(8)^x

cluponka [151]

4 1/2  + 8 3/4

4+8 = 12

1/2 + 3/4 = 2/4 + 3/4 = 5/4 = 1 1/4

12 + 1 1/4 = 13 1/4
