I assume that you mean 3 times 5 feet means how many feet and inches
so the answer is 5 feet and <u>blank </u> inches
or 12 inch in 1 feet so 12 times 5=60 so 60 inches
or you may have forgotton to put a number before the first inch word like 5 feet <u>3</u> inch

20 watches are made since 385 = 15n + 85. 385 - 85 is 300 and 300 divides by 15 is 20.
Answer:
x = 8
y = 21
Step-by-step explanation:
(7x + 12)° and (12x - 28)° are alternate interior angles. Alternate interior angles are congruent. Therefore:
(7x + 12)° = (12x - 28)°
Solve for x
7x + 12 = 12x - 28
Collect like terms
7x - 12x = - 12 - 28
-5x = -40
Divide both sides by -5
-5x/-5 = -40/-5
x = 8
(12x - 28)° + (9y - 77)° = 180° (linear pair)
To find y, plug in the value for x = 8.
12(8) - 28 + 9y - 77 = 180
96 - 28 + 9y - 77 = 180
Combine like terms
- 9 + 9y = 180
Add 9 to both sides
-9 + 9y + 9 = 180 + 9
9y = 189
Divide both sides by 9
9y/9 = 189/9
y = 21
Subtract 6x from both sides to get:
2y=-6x+12
Then divide both sides by 2 to get:
y=-3x+6
