I dont think the answer is always. Because integers are always whole numbers. Hope that helps a little?
Answer:
r = 6 3/23
Step-by-step explanation:
-128+138r=718
add 128 to each side
-128+128+138r=718+128
138r = 846
divide each side by 138
138r/138 = 846/138
r = 846/138
divide top and bottom by 2
r = 423/69
divide top and bottom by 3
r = 141/23
change this to a mixed number
r = 6 3/23
7. 3c+3=84
3c=81
c=27
So either 81/3 but if simplified its 27/1
8. The correct answer would be 55=31+t
Answer:
a = 12 ft, b = 12 ft
Step-by-step explanation:
The triangle is 45 45 90 right triangle
so a = b
Ratio of leg : hypo. = a : a√2
Given hypo = 12√2, so legs a = b = 12
Answer
a = 12 ft, b = 12 ft
Hello! 12 make a dozen. 12 * 6 is 72. 72 cookies make 6 dozen. 2 cups of sugar are needed to make 6 dozen. 36 cookies is 3 dozen, because 3 * 12 is 36. 36 is ½ of 72, so we would need ½ of the amount of sugar needed for 6 dozen cookies for 3 dozen cookies. ½ of 2 is 1. There. 1 cup of sugar is needed to make 3 dozen cookies.
