Answer: 36h, 60+16.2h, and $92.40.
Step-by-step explanation:
n(h)=36h because there are 3 dozen cupcakes made per hour, to get C(h) you just plug in 36h in place of n and simplify, and then for the final answer 2 is plugged into the equation from the second answer.
Answer:
The product 12 × 15 in friendlier numbers is (10 + 2) × (10 + 5) = 180
Step-by-step explanation:
The parameter given are;
To 12 × 15 by changing the numbers into friendlier numbers
The product in 12 × 15 written with friendlier numbers (or in a simplified format can be given as follows;
12 × 15 = (10 + 2) × (10 + 5)
Which gives;
(10 + 2) × (10 + 5) = 10² + 10 × 5 + 2 × 10 + 2 × 5
From which we have;
10² + 10 × 5 + 2 × 10 + 2 × 5 = 100 + 50 + 20 + 10 = 180
Therefore;
12 × 15 = 180.
I believe the answer is D.) 360
Let's see it...
-x+0+(-x)=0 ???
There is a + before the parenthesis, the sign is the same.
-x+0-x = 0
Since the x have equal sign, we add them to get -2x
We have 2x - 0 = 0
Move the zero to the right, so 2x = 0
Divide both for 2...
x = 0
Substitute 0 to x, so -0+0+(-0) = 0
0 = 0 the statement is true
