Answer : The incorrect step is, (A) step 1: -10 + 6x > 8
Step-by-step explanation :
The given expression is:
Now solving this expression step by step.
First -4 distributed over parentheses.
Now solving bracket term, we get:
Now taking like terms together, we get:
Now multiplying this expression by (-1), we get:
Thus, the incorrect step is, (A) step 1: -10 + 6x > 8
B. 3.5( b + c ) - 28.09
C. $108.41
Step-by-step explanation:
The best expression to use to find the total profit of Cindy's pie is 3.5(b+c) - 28.09. The total profit is the total revenue - total cost.
To put it into perspective, let's try an example.
b = 5
c = 12
Total profit = 3.5(b + c) - 28.09
= 3.5 (5 + 12) - 28.09
= 3.5 (17) - 28.09
= 59.5 - 28.09
Total profit = $31.41
Now for part B, we simply use the expression and substitute the values.
b = 24
c = 15
Total profit = 3.5(b + c) - 28.09
= 3.5(24 + 15) - 28.09
= 3.5(39) - 28.09
= 136.5 - 28.09
Total profit = $108.41
Answer:
x<13

Answer:
108 square feet
Step-by-step explanation:
This question is essentially asking us for the area. (Don't be fooled into thinking this is a perimeter question. Imagine if you had a floor with just a ring of carpet on the edges!)
Let's separate this into areas we can understand. The square to the right, with dimensions 6 ft by 6ft, has an area of
A = s*s = 6*6 = 36 square feet
The rectangle that we have left has dimensions 12 ft by 6 ft, so it has an area of
A = l*w = 12*6 = 72 square feet
Add those together to get the total area.
A(rect) + A(square) = 72 + 36 = <u>108 square feet</u>
