Here what we observe
So as we know about subtracting lowest number is subtracted from highest no
So here
Distance must be positive
Just a guess, but the angle inside the triangle that's not x or y is the remaining angle after subtracting the 30 degrees shown. That makes the non labeled angle inside the triangle 150 degrees. since all triangles are 180 degrees, this means x and y add up to 30. They look roughly the same, so i'd guess they're both 15 degrees.
Yes the equations are equivalent
le'ts take a peek at the ages, 9, 6 and 5, so their ratio will be in the order of 9:6:5, what we firstly do is divide the total by that many pieces, namely 100 ÷ (9+6+5) and then distribute accordingly.
Answer:
Part A: 90; Part B: 24.
Step-by-step explanation:
The number of blueberry muffins is 40% of the total number of muffins.
Part A: There are 36 blueberry muffins. This is 40% of the unknown number of muffins, x; this gives us
36 = 0.4x
Divide both sides by 0.4:
36/0.4 = 0.4x/0.4
90 = x
There were 90 total muffins.
Part B: 40% of the total number of muffins, 60, gives us the unknown number of blueberry muffins:
0.4(60) = x
24 = x
There were 24 blueberry muffins.
