The phrase you typed can be written in mathematical form using a replacement of "a number" with the letter "x" (for our unknown).

So we can translate in mathematical form as shown below:

"<em>four more than the product of a number and 3 equals 7</em>"

x * 3 + 4 = 7

and of course we can solve this equation by operating with thenumbers so as to isolate the unknown "x"on one side of the equal sign:

Subtract 4 from both sides:

x * 3 = 7 - 4

x * 3 = 3

Divide both sides by 3 (so as to eliminate the factor 3 multiplying x):

x = 3 / 3

x = 1

And our answer is that the unknown number is 1 (one).

marianne buys 16 bags of potting soil that comes in 5/8 lb. bags. how many pounds of potting soil foes she has.
andriy [413]
One bag of soil is 5/8 pounds.
you have 16 of them.
just multiply 16 by 5/8.
you could just type it into your calculator, or you could do it the long way:
16 *  \frac{5}{8} \\ \frac{16*5}{8} \\  \frac{8*2*5}{8} \\ 2*5\\10

she has 10 pounds of potting soil.

PLEASE PLEASE PLEASE HELP!!!!! 95 points!!!
zysi [14]

The "rule" being described here is nothing more than the input/output of a mathematical function.


For every input 'x' value supplied, you only need to subtract three to it. For every input 'y' value, you only need to add four to it.


Example: I'll use variable 'm' to represent this function. Variable 'p' will represent the current input point.


m(p) = p[x - 3, y + 4] = p[-7 - 3, 0 + 4] = p[-10, 4]. 'p[]" is just the point.

I tried my best hope that help!
