Answer:
112
Step-by-step explanation:
3(7-3) = 3 x 4 = 12
12^2 = 144
144 -4(6+2)
144-4(8)
144-32
112
The ratio of flowers to bouquets is
64:8
With 80 flowers, the ratio would be
80:x
so...
64:8 divide each by 8 to get 8:1
multiply each by 10 to get
80:10
10 bouquets
The opposite angles of a parallelogram are congruent, so you have to set the values of each angle equal to each other and solve for x.
(10x-19)° = (7x+23)°
-7x -7x
3x-19 = 23
+19 +19
3x = 43
÷3 ÷3
x = 43
Then, substitute the value of x back into the equations.
(10x-19)°
(10(14)-19)°
(140-19)°
121°
(7x+23)°
(7(14)+23)°
(98+23)°
121°
12 days. 60 is a quarter of 240. So, multiply 60 by 4 to get 240.
