Answer:
18.9c - 11.2d + 9.3f
Step-by-step explanation:
<u>First, write the equation as adding all the parentheses together like so:</u>
(9.7c - 1.9d) + (9.2c + 1.1f) + (8.2f - 9.3d)
<u>Remove the parentheses:</u>
9.7c - 1.9d + 9.2c + 1.1f + 8.2f - 9.3d
<u>Collect like terms (9.7c and + 9.2c):</u>
18.9c - 1.9d + 1.1f + 8.2f - 9.3d
<u>Collect like terms again (1.9d and - 9.3d):</u>
18.9c - 11.2d + 1.1f + 8.2f
<u>Collect like terms again (1.1f + 8.2f)</u>
18.9c - 11.2d + 9.3f
Hope this helped!
Answer:
80 cookies
Step-by-step explanation:
To find the number of oatmeal cookies sold you would divide 72 by 9.
72 / 9 = 8
This means that 8 oatmeal cookies were sold at the bakery sale. The question wants you to find the combined amount of raisin and oatmeal cookies sold, so add 72 and 8 together.
72 + 8 = 80
80 raisin and oatmeal cookies were sold.
Answer:
b = 64/a³
Step-by-step explanation:
Using the given information, we can only find a relation between a and b. We cannot find any specific value for b.
Since a varies inversely as the cube root of b, we have ...
a = k/∛b
Multiplying by ∛b lets us find the value of k:
k = a·∛b = 1·∛64 = 4
Taking the cube of this equation gives ...
64 = a³b
b = 64/a³ . . . . . divide by a³
The value of b is ...
b = 64/a³
