Answer:

32-12=20 or x=4

Step-by-step explanation:

This is basically saying 8x-3x=20

so first you want to do 8x-3x to end up with 5x

then from there you have the equation..

5x=20

in order to figure out what x is you need to divide 20 by five so you just have the x and get rid of the 5

so 20 divided by 5 = 4

this means x=4 but you need to plug it into the equation

8x= 8 times 4 = 32 and 3x= 3 times 4 = 12

so 32-12=20

Answer:

x=4

where y =3x

8x-3x=20

5x=20

5x/5=20/5

x=4

Pls help I don't understand:

Answer:

Part a) $T(d)=2d+30$

Part b) $T(6)=42\ minutes$

Step-by-step explanation:

Part a) Write an equation for T (d)

Let

d ----> the number of days

T ---> the time in minutes of the treadmill

we know that

The linear equation in slope intercept form is equal to

$T=md+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

The slope or unit rate is

$m=2\ \frac{minutes}{day}$

The y-intercept or initial value is

$b=30\ minutes$

substitute

$T(d)=2d+30$

Part b) Find T (6), the minutes he will spend on the treadmill on day 6

For d=6

substitute in the equation and solve for T

$T(6)=2(6)+30$

$T(6)=42\ minutes$

M is directionly proptional to r squared

sergejj [24]

Answer:

A) 504

B) 8

Step-by-step explanation:

The statement of proportionality can be written as the equation ...

m = kr²

Then we can find k from ...

k = m/r² = 14/2² = 7/2

That is, ...

m = (7/2)r²

Using this relation, we can find m for r=12:

m = (7/2)·12² = 7·72

m = 504 . . . for r = 12

And, we can use the same equation to solve for r when m=224.

224 = 7/2·r²

r² = 64

r = √64

r = 8 . . . for m = 224
