Answer:

8 divided by 1/3 is 24 because you are dividing a fraction so it is basically 8*3 (inverse operations). As for 2/3 it does not have one as a numerator so it automatically is less that 1/3

Step-by-step explanation:

Sry If it doesn't make sense!

If you are confused let me know and I will explain in the comments.

Wrie down the equation of the line that is parallel to 4x - 2y = 7 and passes through (9, -3)

EastWind [94]

Answer:

4x-2y =42 is the required equation

Step-by-step explanation:

given equation is,

4x-2y -7=0---------eqn1

parallel equation of given equation is

4x -2y+k =0-------eqn 2

now passing it through (9,-3), we get,

4×9 + 2×3 +k = 0

or,36+6+k =0

or,42+k =0

or, k= -42

putting the value of k in eqn2

4x-2y - 42=0

4x-2y = 42

A principal of $835 in an account at 3% per quarter simple interest

Tems11 [23]

Take $835 and multiply by 0.3 and you get $25.05
If you add $25.05 to $835 you will get $860.05
Keep adding $25.05 and you will have sums of $885.10, $910.15, $935.20
So your answer is D.

Brittany uses the rowing machine and the stair machine at the gym for an exercise program. Her trainer wants her on an exercise

dangina [55]

Answer:

The equations are: $x+ y = 30$ and $x = 3y$ .

Step-by-step explanation:

We are given that Brittany uses the rowing machine and the stair machine at the gym for an exercise program.

Let the time spend by Brittany on the stair machine be represented by the variable $x$ .

and the time spend by Brittany on the rowing machine be represented by the variable $y$ .

Now, there are two conditions stated by her trainer;

The first condition states that Brittany will exercise for 30 minutes, dividing her time between the two types of machines, that is;

$x + y = 30 \text{ minutes}$

The second condition states that Brittany will spend three times as much time on the stair machine as on the rowing machine, that is;

$x = 3y$

So, the equations are: $x+ y = 30$ and $x = 3y$ .

These equations can be solved either using the substitution method or the elimination method.
