Answer:

$x = 5$

Step-by-step explanation:

Given

$6-3(2x-3)=5(6-x) -4x$

Required

Solve

$6-3(2x-3)=5(6-x) -4x$

Open Brackets

$6-3*2x-3*-3=5*6-5*x -4x$

$6-6x+9=30-5x -4x$

Collect Like Terms

$-6x + 5x + 4x = 30 - 6 - 9$

$3x = 15$

Solve for x

$x = \frac{1}{3} * 15$

$x = 5$

Adams sister want to watch her intake of fat per day.he estimate that the dinner will have 48grams of fat.what percentage of her

zaharov [31]

You have to figure out what 48 percent of 70 is.
Use the formula percent/of = x/100.
So, 48/70 and x/100 you cross multiply the numbers; 48*100 and 70*x and end up with 70x=4800.
Divide both sides by 70, which gives you 68.57.
Round the number up to 69 percent.

Which of the following expressions are equivalent to -19/8 x(-50)

dmitriy555 [2]

1. Move the negative sign to the left.

- $\frac{19}{8}$ $X$ *-50

2. Use this rule: $\frac{a}{b}$ $*$ $\frac{c}{d}$ = $\frac{ac}{bd}$

- $\frac{19x*-50}{8}$

3. Simplify - $\frac{-950x}{8}$

4. Move the negative sign to the left.

-(-950x/8)

5. Simplify 950x/8 to 475x/4

6. Remove parentheses.

The volume of a sphere whose diameter is 18 centimeters is how many cubic centiemters

Arturiano [62]

Answer:

3053.63 cm^3

Step-by-step explanation:

Volumme of a sphere = $\frac{4}{3}\pi*r^3.$

We do not have the radius of the sphere, but we have its diameter.

We know that there is a relationship between radius and diameter.

$d = 2r\\r = \frac{d}{2}$

Then the formula of the volume of a sphere according to its diameter is:

$\frac{4}{3}\pi (\frac{d}{2}) ^ 3\\\\\frac{4}{3}\pi(9)^3 = 972\pi = 3053.63 cm^3\\\\$
