Answer:
x= 14. (ik this not trig but side opp. 30 angle is half the hypotenuse in right triangle). pls give brainliest
Step-by-step explanation:
Given:
Total number of pieces: 117
watch = x
earrings = four times as many earring as watches = 4x
necklaces = half the number of necklaces as earrings = 1/2 * 4x = 2x
bracelets = necklaces = 2x
x + 4x + 2x + 2x = 117
9x = 117
x = 117/9
x = 13
watches: x = 13
earrings: 4x = 4(13) = 52
necklaces: 2x = 2(13) = 26
bracelets: 2x = 2(13) = 26
13 + 52 + 26 + 26 = 117
There are 13 watches, 52 earrings, 26 necklaces, and 26 bracelets.
Answer:
y=2
Step-by-step explanation:
12 - 6 = 6
6 also = 3y
6 / 3 = 2
y = 2
CHECK:
(3*2=6) + 6 = 12
6+6 = 12
Correct
Answer:
11
Step-by-step explanation:

Answer:
n = 185/9
Step-by-step explanation:
(6n-25) + (3n + 20) = 180
Combine like terms
9n -5 = 180
Add 5 to each side
9n - 5 +5 = 180+5
9n = 185
Divide each side by 9
9n/9 = 185/9
n = 185/9
