First piece is x
second piece is y. y=4x
third piece is z. z=3y=12x
x+y+z=680
x+4x+12x=680
17x=680. x=40cm y=160cm. z=480cm
Her time was 0.02 seconds short of being equal to the 2nd fastest time. In conclusion, no, she was slower.
Answer:
13
Step-by-step explanation:
since the inside of a triangle is equal to 180
180-42-73=65
65/5=13 so 13 should be the answer.
Answer:
see attached
Step-by-step explanation:
3x(x − 2)(5x + 2)
- (x − 2)(5x + 2) expand
- 5x² - 8x - 4
- 3x ( 5x² - 8x - 4) expand
- 15x³ - 24x² - 12x
Those are vertical angles and vertical angles are always congruent, meaning they're equal. To find x, you must set 6x+5=83 and solve for x.
