20×+4=4(5x+1) how many solution are in this equation

Mathematics

Tomtit [17]4 years ago

Simplify both sides of the equation

(20)(4)= 4(5x+1)

Simplify

80 = 20x+4

Flip the equation

20x+4 = 80

Subtract 4 from both sides

20x+4-4 = 80-4

20x = 76

Divide both sides by 20

20x/20 = 76/20

x= 3.8


There is one solution in this equation

  • Volume of a Rectangular Prism: V = lwh

Step-by-step explanation:

<u>Step 1: Define</u>

l = 4 cm

w = 6 cm

h = 14 cm

<u>Step 2: Solve for </u><em><u>V</u></em>

  1. Substitute:                    V = (4 cm)(6 cm)(14 cm)
  2. Multiply:                        V = (24 cm²)(14 cm)
  3. Multiply:                        V = 336 cm³

And we have our final answer!

If the product of roots of the equation given below is 4, then find the value of m.
Vikentia [17]

Answer:

m=-2

Step-by-step explanation:

As the product of the roots of a quadratic equation is c/a in ax^2+bx+c=0

here a=2, b=+8, c=-m^3

Given c/a=4

-m^3/2=4

-m^3=8

m^3= -8

m=-2.

astraxan [27]
All the students can fit into the 60 second video and there will be 15 seconds left. 5 times 9 = 45. So, all of the students will equal a video of 45 seconds. To figure out the time left, you subtract, 60-45, which equals 15 extra seconds.
