|8m + 7| - 5 = 60

Answer:

g= -5

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    84-(4*(1-4*g))=0

 84 -  4 • (1 - 4g)  = 0

3.1     Pull out like factors :

  16g + 80  =   16 • (g + 5)

16 • (g + 5)  = 0

4.1      Solve :    16   =  0

This equation has no solution.

A a non-zero constant never equals zero.

4.2      Solve  :    g+5 = 0  

Subtract  5  from both sides of the equation :  

                     g = -5

Step-by-step explanation:

Step 1: Define equation

84 = 4(1 - 4g)

Step 2: Solve for g

Step 3: Check

Plug in g into the original equation to verify it's a solution.

Here we see that 84 does indeed equal 84.

∴ g = -5 is a solution of the equation.

(0.16d - 10) dollars

Step-by-step explanation:

"Harry earned d dollars mowing lawns. He put 20% of his earnings in the bank and paid back $50.00 to his father."

Start with d dollars.

He put 20% of d dollars in the bank. 20% of d is the same as 0.2d.

Now he has d - 0.2d = 0.8d

He paid his father $50.

Now he has 0.8d - 50

"He spent  one-fifth of the remaining money on a video game. Which expression represents the amount he spent on the video game?"

He spent 1/5 of 0.8d - 50 on a video game, so he spent on the video game:

1/5 * (0.8d - 50) = 0.16d - 10

Answer: 0.16d - 10 dollars

(You forgot the "d" in the answers."

(0.16d - 10) dollars

Step-by-step explanation: 6^2+7^2=85

8^2=64

Answer:

Step-by-step explanation:

As all edges of a cube are expanding at a rate of 2 centimeters per second.

i.e ds/dt = 2 cm/s

The formula of volume of cube: V = s³

Differentiating the volume:

dv/dt = 3s²

Write ds/dt following derivative of volume

dv/dt = 3s² ds/dt

plug in the value: ds/dt = 2 cm/s

dv/dt = (3s²) (2)

dv/dt = 6s²

Given the edge is 2cm.

so plug in the value: s=2

dv/dt = 6s²

          = 6(2)²=6(4)=24 cm³/per second

SIMILARLY,

When the edge is 14cm

dv/dt = 6s²

plug in the value: s=14

dv/dt = 6s²

         = 6(14)²=6(196)=1176 cm³/per second

Thus,

The volume will be:

(a) 24 cm³

(b) 1176 cm³

Given:

Expanding rate,

Let,

(a)

When,

then,

→ [tex]\frac{dx}{dt} = 2 \ cm/sec[/tex]

Let,

→ [tex]V = x^3[/tex]

→ [tex]\frac{dV}{dt} = 3x^2 \frac{dx}{dt}[/tex]

        [tex]= 3\times 2^2\times 2[/tex]

        [tex]= 3\times 4\times 2[/tex]

        [tex]= 24 \ cm^3[/tex]

(b)

When,

then,

→ [tex]\frac{dx}{dt} = 2 \ cm/sec[/tex]

Let,

→ [tex]V = x^3[/tex]

→ [tex]\frac{dV}{dt} = 3x^2 \frac{dx}{dt}[/tex]

        [tex]=3\times 14^2\times 2[/tex]

        [tex]= 1176 \ cm^3[/tex]

Thus the above answer is correct.

The Distributive Property

Answer:

The equation [tex]x^2 + 6x -5 = 4x^2[/tex] have 2 non-real solution, 2 imaginary solutions.

Step-by-step explanation:

Using the Discriminant to find the number and type of solutions to [tex]x^2 + 6x -5 = 4x^2\\x^2-4x^2+6x-5=0\\-3x^2+6x-5=0[/tex]

The discriminant is: [tex]b^2-4ac[/tex]

We have a = -3, b=6 and c=-5

Putting values and finding discriminant

[tex]b^2-4ac\\=(6)^2-4(-3)(-5)\\=36-60\\=-24\\[/tex]

So, we get discriminant = -24

if discriminant  < 0 the solution will have two non-real imaginary solutions.

In our case discriminant  < 0 i,e discriminant  = -24

So, The equation [tex]x^2 + 6x -5 = 4x^2[/tex] have 2 non-real solution, 2 imaginary solutions.

Answer: 90

Step-by-step explanation:

90 degrees. x=90-47=43 degrees.

Step-by-step explanation: We can find the measure of its complement

by taking 90 minus the measure of the original angle.

So we have 90 - 47 which is 43.

So the measure of its complement is 43°.

Answer:

Area of rectangular garden = lxb = 10*5

                                             = 50 sq. inch

when area increases by six times

new area = 50*6 = 300 sq inches

now,

let x be increasement in both  length and width

(5+x) (10+x) = 300

50 + 5x + 10x + x² = 300

x² + 15x - 250 = 0

x²+ 25x-10x -250 = 0

x(x+25) - 10 (x+25) = 0

( x-10) (x+25) = 0

either x + 25 =0

x = -25 length can be negative

0r x-10 = 0

x = 10

so 10 inches is increase on both side

Answer:

$2,430

Step-by-step explanation:

Scale of the drawing = ⅓ in. to 1 ft

Measurement of the bathroom on paper = 3 in. by 3⅓ in.

Actual measurement of the bathroom:

3*3 = 9 ft

3⅓ * 3 = 10 ft

Area of the bathroom = 9*10 = 90 ft²

Let's find how many square tiles would cover 90 ft².

The side length of 1 tile is said to be ⅓ ft.

Therefore, the area of 1 tile would be ⅓*⅓ = ⅑ ft².

Number of tiles that would cover 90 ft² would be:

90/⅑ = 90*9

= 810 tiles

If 1 tile cost $3.00, therefore 810 tiles would cost:

810 * 3 = $2,430.
