Mrs. Sanchez has a bag of assorted nuts that contain almonds, pecans, and walnuts. 1/3 of the nuts are almonds and 3/4 of the remainder are pecans. There are 300 nuts in the bag. How many walnuts are in the bag
Answers
remainder is 300 - 100 = 200
pecans = 3/4*(200) = 150
walnuts = 300 - 100 - 150 = 50
there are 50 walnuts in the bag

2/3, -0.6, 0.65, 4/5
Answers
if decimals
2/3=0.66666666
4/5=8/10=0.8
so the order is
-0.6, 0.65, 0.66, 0.8 or
-0.6, 0.65, 2/3, 4/5
if conver to fractions then
since -0.6 is negative, it is smallest, no need to convert
0.65=65 hundreths=65/100
2/3=66/99=prety close
4/5=8/10=80/100
order is
-0.6, 65/100, 66/99, 80/100 or
-0.6, 0.65, 2/3, 0.8
Now lets see....
4/5 = 0.8
Answer: -0.6 , 0.65, 2/3, 4/5
B. 5/10

Firstly, since these two fractions have the same denominator, add the numerators up:
While it appears that the answer is -6/4, you can further simplify it by dividing the numerator and denominator by 2:
Your answer is
x-y=-4

add the 2 equations together
2x+x+y-y=-8-4
3x=-12
divide by 3
x=-4
subsitute
-4-y=-4
addd 4 to both sdies
-y=0
the solution is (x,y) (-4,0) or D
I have decided to use Elimination by Addition.
Add the two equations together
3x = -12
Divide both sides by 3
x = -4
Substitute -4 for x in the second equation.
-4 - y = -4
Add 4 to both sides
-y = 0
y = 0
Check
2(-4) + 0 = -8
-8 = -8 This checks.
-4 - 0 = -4
-4 = -4 This also checks.
The solution set for this system is as follows:
S = {(-4,0)}
That would be option D.
