If RS arc is = to the RS central angle then the RS arc would be 20 degrees, but if the RS is on the Circumference then the RS arc would be 40.
Answer: x = 28
Step-by-step explanation:
x + 20=3x-36
20=2x-36
56=2x
56/2=28
So 28= x
Answer: 2.8%
Step-by-step explanation:
Give, In a certain month a family spent $750 on food
In third month the family spent $729 on food .
i.e. Expenditure on food in a certain month = $750
Expenditure on food in third month = $729
Decrease in monthly spending on food = (Expenditure in a certain month )- (Expenditure in third month )
= $750 - $729
= $21
Now , the percentage decrease in the month spent on food will be :
Hence, the percentage decrease in the month spent on food is 2.8%.
Answer:
7n + 5 − 9n = 8 − 2n − 3 = true
-2 n + 5 = 5 - 2 n = true
Step-by-step explanation:
Left-hand side:
Simplify the following:
7 n - 9 n + 5
Grouping like terms, 7 n - 9 n + 5 = 5 + (7 n - 9 n):
5 + (7 n - 9 n)
7 n - 9 n = -2 n:
Answer: -2 n + 5
____________________________
Right-hand side:
Simplify the following:
-2 n - 3 + 8
Grouping like terms, -2 n - 3 + 8 = (8 - 3) - 2 n:
(8 - 3) - 2 n
8 - 3 = 5:
Answer: 5 - 2 n
