Answer:
26-3.50-8x=16.18
Step-by-step explanation:
To create an equation representing what she spent, we need to start with the money she had and end with the money she has left.
We know that she originally had $26, but when she was done shopping, she had $16.18. To get from $26 to $16.18, you have to subtract the cost. That gives you 26 - [ cost ] = 16.18
We know that she spent $3.50 on a notebook and 8 pens of an unknown cost. The unknown cost can be represented by x. To find the total cost, you must add the costs of what she bought together. That gives you 3.50 - 8x.
Plug the expression of the cost into the equation, and boom it's done.
26 - 3.50 - 8x = 16.18
Answer=52x
65%=65/100=.65
80x*.65=52x
60% of 80x is 52x
5 feet is equal to 60 inches. 60 inches divided by 2.5 inches per hour means it would take 24 hours for the drill to reach five feet (assuming it maintains the same rate of digging)
Answer:
For the linear equation y = mx + b, m is the slope (the change in y for a change in x) and b is the y intercept, i.e. the value of y when x is zero. For this problem, b (y-intercept) is the money Nicole would make even if the hours she babysits was zero, i.e. the flat fee. Therefore, b = $3. The slope m is the money she makes babysitting per hour, i.e. $5. Therefore, the equation is
y = 5*x + 3.
In function notation we just replace y with f(x) (meaning the output of the function f for input x):
f(x) = 5*x + 3.
In five hours (x = 5), Nicole would make:
y = 5*5 + 3 = 25 + 3 = $28.
