R-7=7 add the seven from both sides, leaving the r alone, because this is what you are trying to find. Thus the answer is r=14.
A. 3 days a week: 12/80=0.15
B. MORE than 4 days a week: 28/80= 0.4625
C. at LEAST once a week: 0.8125
Correct.
Answer:
These are the properties of a parallelogram
• Opposite angles are equal
• The sum of all the angles is equal to 360 degrees
• Opposite angles are equal
• When the diagonals of a parallelogram are drawn, they bisect each other
• When a diagonal is drawn to separate the parallelogram into two, the two separate sides are equal when compared
• The sum of two adjacent angles in parallelogram is equal to 180 degrees
Step-by-step explanation:
For example,
Opposite angles (A and D) and (B and C) are equal
The sum of all the angles give 360 degrees, angles A + B + C + D = 360
Side AB is equal to side CD (/AB/ = /CD/)
The sum of adjacent angles A and C gives 180 [angles (A + C ) = 180]
Choose the option similar to any of these properties in the question
I think it may be 5+3 and carry the one up top to get the sum of 56.
