Answer:
The temperature at midnight is -12 degree Celsius
Step-by-step explanation:
Given -
Temperature at 6:00 PM = -20 degree Celsius
Let the temperature at midnight be X degree Celsius
From midnight to 6:00 am, the temperature rose by 8 degree Celsius
X - (-20) = 8
X = 8-20
X = -12 degree Celsius.
The temperature at midnight is -12 degree Celsius.
Distribute the 5 to each of the numbers so you should get 5x+5+5x+5+5x+35. after this you should combine like terms, all of the 5’s & the 35 and 5x’s. you should have 15x+45. then you divide 45 by the 15 and you should get x=3
Answer:
41,6 cm
Step-by-step explanation:
Formula for Perimeter of a rhombus: P = 2L + 2H (H is the height, L the length)
Perimeter: 160 cm = 2L + 2(38,4 cm), or
160 cm + 76.8 cm + 2L, or
83.2 cm = 2L
and so the height (altezza) is H = 83.2 cm / 2 = 41,6 cm
