you cannot show too much "work"
basically, you remove what is common to all of the factors, and then put brackets, as it will be multiplied back in, remember that when you multiply exponents with the same base, its same as adding them, so subtract to remove...
you can seperate two of the variables , then factor, then subtract the last one from those two, because it cannot be factored out , as in part2 #2
#7
20%•$300
$60
300-60
240
Hope this helps!!
Can you show me the options?
Answer: X < 3
Step-by-step explanation:
-6 < -2x -- Divide by -2
3 > x --- The sign flips when dividing in negative numbers.
Since three is greater than x
X is less than 3
meaning
X < 3
<span>x=number of brown shoes
2x=number of black shoes (twice as many black shoes as brown shoes)
so x+2x=66
add like terms 3x=66
solve for x by dividing 3; x=22
so there are 22 brown shoes and 44 black shoes (2 x 22= 44)</span>
