Answer:
<em>5.195</em>
Step-by-step explanation:
To solve the different operations of a mathematical expression there are rules that must always be followed, that is, there is a hierarchy of operations that must be respected.
The hierarchy of operations works as follows:
First, operations in brackets, brackets or braces are resolved independently.
Next, the powers and roots are realized.
It continues to solve multiplications and divisions.
Finally, the addition and subtraction are carried out, regardless of the order.
6 x 0.9 + 0.1 / 4 -0.23 =
First, multiplications and divisions:
5.4 + 0.025 - 0.23.
Then, addition and subraction:
5.195
Marcus currently has $42 and
has plans to save an additional $5 each week to buy a pair of shoes. He made a
table showing the total amount of money he will have saved for different weeks.
Since $5 per week is the slope and $42 is the y intercept
The equation of the line is
equal to:
Y = 5x + 42
<span>-5x +y = 42</span>
Answer:
Step-by-step explanation:
Given the function :
f(x) = 7x - 8
Evaluate the given values of the independent variable and simplify.
a. f(7)
b. f(x + 5)
c. f(-x)
A.) f(7)
f(7) = 7(7) - 8
= 49 - 8
= 41
B.) f(x + 5)
7(x + 5) - 8
7x + 35 - 8
7x - 27
C.) f(-x)
7(-x) - 8
-7x - 8
It would be 2,700 miles because since 1 inch is equal to 400 miles, you have to plug in 6 and 3/4 of an inch and multiply that by 400 and get 2,700
