You cant add them so it is probably a trick question.
Step-by-step explanation:
Answer:
s = 1,811 square foot
Step-by-step explanation:
Here, we want to calculate the area of the roof.
The best way to proceed here is by substitution.
We simply substitute the length and the price into the bid price equation to get the area of the roof.
From the original equation, the formula to use is ;
P = 1.85s + 4.2f
now from what we are given; s = ?
f = 190 feet and P = $4148
substituting these values, we have;
4148 = 1.85s + 4.2(190)
4148 = 1.85s + 798
1.85s = 4148 -798
1.85s = 3350
s = 3350/1.85
s = 1,810.810810810811
To the nearest square foot, s = 1,811
Danica has -$23, but deposits $40
Add the two numbers
40 + (-23) = 40 - 23 = 17
Danica has $17 in her bank.
hope this helps
The value of the expression will be equal to 55.
<h3>What is an expression?</h3>
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that 6 is added to the product of 7 and a number 7. The expression will be written as,
E = 7 x 7 + 6
E = 49 + 6
E = 55
Therefore, the value of the expression will be equal to 55.
