How to solve with elimination: with the equations on the top, add the number on top and bottom if they share a variable such as x. do the rest for all of the numbers.
Answer:
a) $70
b) 4000 items
c)$4.67/hr
Step-by-step explanation:
a) simplest, 28 (per 1000) x2 plus 14 for 500
b) 28*4=112. it could be 3.57143, but no one wants part of an item
c) 28/6=4.66667
Answer:
the answer is C
Step-by-step explanation:
i got da best $80 calculator
Answer:
x=12
Step-by-step explanation:
We know that a right angle is 90 degrees. So we can make the equation
Now, we can solve fore X! We can combine 35 and 7 to make the equation
. In order to isolate x we have to subtract 42 from both sides, getting us the equation
Now, in order to isolate x we must divide each side by 4, getting us the equation
. To prove that x=12, we can subsitute x for 12. This means that we can do
which simplified, is 90=90, making x=12 true. Hope this helps :)
Answer:
Look below
Step-by-step explanation:
First you multiply the top and bottom
5/12 x 6/7
5x6 and 12x7
you get your new fraction of 30/84
then you simplify it by 6 to get 5/14
hope this helps
