Saravan has a bushel basket of apples to sell at his fruit stand. 2 out of every 10 cannot be sold because they are not ripe yet

tigry1 [53]

Answer:

80 percent

Step-by-step explanation:

2 out of 10

the ten has to be turned into 100 to make it a percentage. so 10 times 10 is 100 and 2 also has to be multiplied by 10 which is 20. 100-20 is 80 which means 80 percent of his apples arent ripe.

$\huge\text{Hey there!}$

$\large\text{What is the \bf{difference from 10 and 12}}\large\text{ ?}$

$\large\text{The word \underline{DIFFERENCE} usually it means \underline{SUBTRACT} in}\\\large\text{mathematical terms.}$

$\large\text{So, we will reword the question saying 10 SUBTRACTED by 12}$

$\large\text{10 - 12 = \bf -2}$

$\large\text{12 - 10 = \bf 2}$

$\boxed{\huge\textsf{The difference from 10 \& 12 is: \boxed{\huge\text{\bf -2 or 2 }}}}\huge\checkmark$

How many solutions does the system have?

Mrac [35]

Answer:

A Exactly one solution

Step-by-step explanation:

$\left \{ {{6x-3y=9} \atop {6x+y=9}} \right.\\\\\left \{ {{6x-3y=9} \atop {-6x-y=-9}} \right\\\\Then, \\\\-4y=0\\\\\\ y=0\\\\$

Putting y=0 at second equation, we have

$-6x=-9\\\\x=\frac{9}{6} =\frac{3}{2}$

The unique solution is $(\frac{3}{2} , 0)$
