White flour makes up 2 / (2+3) of the total 10 cups: 2/5 of the total 10 cups.
2/5 times 10 is 4 cups.
You'll need 4 cups white flour and 6 cups whole wheat flour, making a total of 10 cups of flour.
Combine the two equations in the right amounts to eliminate y :
-2 (2x + 3y) + (3x + 6y) = -2 (17) + 30
-4x - 6y + 3x + 6y = -34 + 30
-x = -4
x = 4
Solve for y :
2x + 3y = 17
8 + 3y = 17
3y = 9
y = 3
Answer:
Step-by-step explanation:
Given:
We want to find the value of 
.
Law of sines can be used to solve this problem:
(note - let x represent the missing side length.)
1. set up proportion.
sin 90°/25 = sin 55<span>°/x
2. solve.
(x) sin 90</span>° = (25) sin 55<span>°
(x) sin 90 </span>°/sin 90° = (25) sin 55° / sin 90<span>°
</span>
x = 20.4788011072
rounded to nearest tenth = 20.5
