Part 1. Your friend is not right because 1\5 is equal to 20%, which is not equal to 25%.
Part 2. The service fee is $18.60 because 10% of 186 is 18.6
A=TX
Rewrite it
Tx=a
Divide t both sides to get x alone
Tx/t=a/t
Solve
X= a/t
Drum role please..... it’s 7
-1 goes on the number that is -1.
1.75 goes on the 3rd line in between 1 and 2.
-2 goes on the number -2.
-2 1/2 on the 2nd line after 2.
-5/2 or -2 1/2 goes on the 2 line before -2.
And 9/4 or 2 1/4 goes on goes on the 1st line after 2.
Hope this helps!! :)
Answer:
0.267 square units (or 8/30 square units)
Step-by-step explanation:
width = 3 rectangles
length = 10 rectangles (left to right)
area = width * length = 30 rectangles
the striped rectangle is made up of 8 regular rectangles
thus, (area we want) / (total area) = 8/30 of the whole ≈ 0.267 of the whole
the whole is 1 square unit, so 0.267 of 1 square unit = 0.267 * 1 square unit = 0.267 square units
