Plzzzzzzzzzzzzzzzzz HELP ME on this problem: 10/ 4 = x + 8/ x – 1. 50 Points available
USPshnik [31]


Equation: SOLVE


Solution for 10=4(x-1)-(x-8) equation:

Simplifying
10 = 4(x + -1) + -1(x + -8)

Reorder the terms:
10 = 4(-1 + x) + -1(x + -8)
10 = (-1 * 4 + x * 4) + -1(x + -8)
10 = (-4 + 4x) + -1(x + -8)

Reorder the terms:
10 = -4 + 4x + -1(-8 + x)
10 = -4 + 4x + (-8 * -1 + x * -1)
10 = -4 + 4x + (8 + -1x)

Reorder the terms:
10 = -4 + 8 + 4x + -1x

Combine like terms: -4 + 8 = 4
10 = 4 + 4x + -1x

Combine like terms: 4x + -1x = 3x
10 = 4 + 3x

Solving
10 = 4 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.
10 + -3x = 4 + 3x + -3x

Combine like terms: 3x + -3x = 0
10 + -3x = 4 + 0
10 + -3x = 4

Add '-10' to each side of the equation.
10 + -10 + -3x = 4 + -10

Combine like terms: 10 + -10 = 0
0 + -3x = 4 + -10
-3x = 4 + -10

Combine like terms: 4 + -10 = -6
-3x = -6

Divide each side by '-3'.
x = 2

Simplifying
x = 2

Please help cause I don’t know how to do this
zalisa [80]

Answer:

  4 GB

Step-by-step explanation:

Let "g" represent the number of gigabytes of data used. Then the phone bill is computed as ...

  bill = 65 + 12g

Aurora's bill is 113, so we can put that value into the equation and solve for g.

  113 = 65 + 12g

  48 = 12g . . . . . . subtract 65 from both sides of the equation

  4 = g . . . . . . . . . divide both sides of the equation by 12

Aurora used 4 gigabytes of data in September.

_____

You can also use your mathematical reasoning to solve this problem. The total bill consists of two charges: a fixed charge of 65 and a charge that depends on data. If you subtract the fixed charge from the bill, you find that the charge that depends on data is 113-65 = 48.

The data charge is 12 times the number of gigabytes. The data charge on the bill is 48, which is 12 times 4. Then the number of gigabytes is 4.

As the figure is not attached, I have attached the figure using the link- https://cdn.ple.platoweb.com/EdAssets/6764fbd04e1f4014be049f2831fd4e8c?ts=635356393812430000

Answer:

Area is 30 square inches.

Step-by-step explanation:

Given:

The wooden cutout of the lightning bolt consists of 2 right angled triangles with the legs being 10 inches and 3 inches.

The area of this lightning bolt will be equal to the sum of the areas of the two right angled triangles.

The area of a triangle of base 'b' and height 'h' is given as:

A=\frac{1}{2}bh

Here, b=3, h=10. Plug in solve for area of one of the triangles.

Therefore, area of the right angled triangle is:

A=\frac{1}{2}\times 3\times 10=\frac{30}{2}=15\ in^2

Now, the two right angled triangles are congruent. So, total area is twice the area of one of the triangle.

Therefore, total area of the lightning bolt is 2\times 15 = 30 in².
