Answer:

Step-by-step explanation:

Here you go mate

step 1

20-4x-15-4x=-6x-45+8x  equation

step 2

20-4x-15-4x=-6x-45+8x  simplify for x

20+(-4x)+(-15)+(-4x)=(-6x)+(-45)+8x

step 3

(-4x+-4x)+(20+(-15)=(-6x+8x)+(-45)  add brackets to seperate the equations

step 4

-8x+5=2x+-45  combine the terms that are alike

step 5

-8x+5(-2x)=2x-45(-2x)  subtract -2x(the ones in the brackets)

-10x+5=-45

step 6

−10x+5(-5)=−45(-5)  subtract -5

-10x=-50

step 7

-10x/-10=-50/-10  divide by -10

step 8

50/10  Divide

Answer: x = 5

Step-by-step explanation:

Hey there! If you have any questions, feel free to let me know in the comments.

Step 1: Simplify  20 - 4x - 15 - 4x  to  5 - 8x.

5 - 8x = -6x - 45 + 8x

Step 2: Simplify -6x - 45 + 8x to 2x - 45.

5 - 8x = 2x-44

Step 3: Add 8x to both sides.

5 = 2x - 45 + 8x

Step 4: Simplify 2x - 45 + 8x to 10x - 45.

5 = 10x - 45

Step 5: Add 45 to both sides.

5 + 45 = 10x

Step 6: Simplify 5 + 45 to 50.

50 = 10x

Step 7: Divide both sides by 10.

50/10 = 10x/10

Step 8: Simplify 50/10 to 5.

x = 5

Write the equation in standard form of a line that is parallel to the graph of 2x + y = 5 and whose y - intercept is (0,4).
babunello [35]

The line that is parallel to this line will have the same slope of this line, as the two will never intersect. They will run side by side. The line y = 2x - 5 is written in slope-intercept form, which is y = mx + b. The value of m represents the slope, and in this equation m = 2. Therefore, the line we are looking for will have a slope of 2 also.

That line should also be in slope-intercept form. We now know the value of m, but we also know the value of x and y. The ordered pair (8, 10) is a point on the line, and every ordered pair is in the form (x, y). Therefore, x = 8 and y = 10. We can plug those values into y = mx + b, along with m = 2. That gives us:

10 = 2(8) + b We need to solve for b.

10 = 16 + b

b = -6

What is the value of x?​
Kazeer [188]

Answer:

Step-by-step explanation:

The volume of a sphere is

V=\frac{4}{3}\pi r^3

We are told our volume is 500pi/3, so we fill that in and solve for r:

\frac{500\pi}{3}=\frac{4}{3}\pi r^3

Start by multiplying both sides by 3 over 4 pi:

(\frac{3}{4\pi})\frac{500\pi}{3}=(\frac{3}{4\pi})\frac{4\pi}{3}r^3

Simplifying gives us

125=r^3

Take the cubed root of both sides to get that

r = 5

Solve for t in scientific formula d=rt
yarga [219]
The problem is: d=rt
you are solving for r

d=rt
--  --
t    t


you divide both sides by r, so your answer is:

d/t=r or r=d/t

I hope this helped! :))
