when rounding up, decimals tend to lose accuracy, thus the rounding, due to that, fractions will always be the most accurate to represent the value, but let's go ahead
3/5 = 0.6 <- rounded up to one decimal
3/4 = 0.75
= 0.8 <- rouned up to one decimal as well
if we add them up 0.6 + 0.8 = 1.4.

in this case, rounding up each result to 1 decimal, we end up with the same value, mind you that the instructions never said to round it to a certain amount of decimal places, if we do round it to two decimal places, the value will be 1.35 for both cases, and accurate on each.
Hello,
I don't know how you say it in US but
in french we say "<span>the difference of three times a number x and seven"
(la différence entre le triple de x et 7)</span>
Let x = the length of each side of the square.
Therefore the dimensions of the rectangle are x and x/2.
Because the perimeter of the rectangle is 15 inches, therefore
2x + 2(x/2) = 15
2x + x = 15
3x = 15
x = 5 in.
The perimeter of the square scarf is 4x = 4*3 = 12 in.
The area of the scarf is 3*3 = 9 in²
Answer:
Perimeter = 12 in
Area = 9 in²
Answer:
C
Step-by-step explanation:
y is greater or equal to 0
x is also greater or equal to 0
you can see that only one answer choice can be the answer
the line is x-y = 2
the upper side is x-y <= 2
proves that c is the answer
