45.2/0.2= something
we might like to make all the numbers whole numbers (1,2,3,4,5,..)
to keep fractions the same, we must multiply the top number and bottom number by the same number if we want to manipulate it
we want to move the decimal place 1 place to the right so we multiply by 10
do the same on top and bottom so 10/10 times 45.2/0.2=452/2=226
Answer:
they are congruent it just they are shown differnt ways one has the angle on th ebottom and one has one to the left

Answer:
Let's call:
f = price of 1 cup of dried fruit
a = price of 1 cup of almonds
In order to build the linear system, you need to consider that the total price of a bag is given by the sum of the price of cups times the number of cups in each bag, therefore:
Solve for a in first equation:
a = (6 - 3f) / 4
Then substitute in the second equation:
41/2 f + 6 · (6 - 3f) / 4 = 9
41/2 f + 9 - 9/2 f = 9
16 f = 0
f = 0
Now, substitute this value in the formula found for a:
a = (6 - 3·0) / 4
= 3/2 = 1.5
Hence, the cups of dried fruit are free and 1 cup of almond costs 1.5$
