Answer:
12x<180
14
Step-by-step explanation:
12x<180
x<180/12
x<15
Since x has to be less than 15, he took at most 14 people.
Answer:
Step-by-step explanation:
First rearrange all equations into this format:
that will result in:
then we'll multiply an equation with a number such that we have same numbers on both equations (with only different signs). So we can add them
Here you can see that we've multiplied the first equation with (-3) so that we have -9x on one equation and 9x on the other. Now when we add the two equations the 9x and -9x terms will cancel out (or eliminate)
now that we've found the value of y
we'll use this value in any of the two equations to get the value of x.
let's put y in the first equation:
566.3638407 is the answer, I used a TI-34 calculator.
9/36 and 1/4 because you and divide and multiple those
