Answer:
42
Step-by-step explanation:
let the number be x
4/7 of x
(4/7) × x
4x/7
As stated in the question:
x=4x/7+18
=x-4x/7=18
=(7x-4x)/7=18
=3x/7=18
3x= 18×17
3x= 126
x=126/3
x=42
Answer:
Step-by-step explanation:
Let y represent the amount that Marina earns for babysitting.
Let x represent the number of hours of babysitting.
If we plot the graph of y on the vertical axis and x on the horizontal axis of a graph,
the slope which is expressed as
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
Slope = (23 - 15)/(2 - 1) = 8
We would model the function in the slope intercept form which is expressed as
y = mx + c
Where c represents the intercept.
To determine c, we would substitute y = 15, x = 1 and m = 8 into y =mx + c. It becomes
15 = 8 × 1 + c
15 = 8 + c
c = 15 - 8 = 7
The function that describes the sequence would be
y = 8x + 7
Answer:
It cannot be divided by any number and equal a whole number.
Step-by-step explanation:
Okay, so I'm going to give an example of the simplifying process.

If you were to just type this in to a calculator you would get 15.58 and so on, so that means we have to just simplify instead of solving for accuracy purposes.
So take 243 and divide it by a number that can go into it equally. I'm going use 3. When you do that you get 81. Usually when I do this I draw it out to better see it, so I'm going to try for you. The 3 is prime so we can't simplify that term anymore, but you can still simplify the 81, so that is what we do next. I'm going to use 3 to make it easier in the end results. Notice 3 is prime but 27 still is not, so we repeat this process again. I'm gonna stick with 3. Now simplify the 9.
243
3 81
3 27
3 9
3 3
For every pair of number we have that are the same we get to put one outside the sqareroot sign (I know that sounds confusing). Start by listing them like this.
3 x 3 x 3 x 3 x 3
Now organize into groups of two.
(3x3)(3x3)(3) Notice we have two groups that are paired. This means we can take two 3's and bring them outside the squareroot sign. Like this

The lone 3 just goes back in the squareroot. once you can't find a number to divide the number inside the sign by you have simplified the expression completely. Hope that makes some sense
since alie ate 15 gram and there are 12 grams in every 8.
what i did, I made a table that looks like
once you make a table that looks like this, in this kind of situations.
multiply across ( yellow ones)
and then divide by the green one
and then you'll get the answer
