Answer:
24 = no. of dozens of donuts
60 = no. of dozens of cookies
Step-by-step explanation:
The ratio of no. of dozens of donuts to no. of dozens of cookies is 2 to 5
Let 2x = no. of dozens of donuts
and 5x = no. of dozens of cookies
Then 2x + 5x = 84
7x = 84
x = 12
So, 2x = 2(12) = 24 = no. of dozens of donuts
and 5x = 5(12) = 60 = no. of dozens of cookies
Check: 24/60 = 2/5 and 24 + 60 = 84
Subst. the given x and y values: 6(-1)^4 * (3)^3
6 * 27 = 162
Note that you MUST do the exponentiation first.
Also note that your post would be much clearer if you'd please use " ^ " to denote exponentiation: 6x^4 * y^3
Yea, -7 is the correct answer

Answer:
a = 6, b = 22.5
Step-by-step explanation:
One triangle is 2.5 times bigger than the other.
9*2.5=22.5 which means b = 22.5
15/2.5=6 which means a = 6
