Answer:
$24
Step-by-step explanation:
You will plug in 8 for x :)
30 - (3/4)x
Since he loses 3/4 a dollar for every hour he can't work, (3/4) x 8 = 6. He will lose 6 dollars from this. 30 - 6 = 24.
His final profit is 24.
let's bear in mind that a year has 12 months, so 30 months is really 30/12 years.
The answer for the first question is the second option.
The answer for the second question is 192
In one hour the plane will cover a distance of 1238 km.

What is a linear equation?</h3>
- A linear equation has one or two variables.
- No variable in a linear equation is raised to a power greater than 1.
- No variable is used as the denominator of a fraction.
- A linear equation is defined as an equation that is written in the form of ax+by=c.
- When solving the system of linear equations, we will get the values of the variable, which is called the solution of a linear equation.
solving this we will get the valve of Y is x is given.
calculation:-
today distance = 9904 km.
total time is taken = 8 hours.
∴total distance covered in one hour = 9904/8
= 1238 km.

Answer:
b = 21/15
Step-by-step explanation:
0.6+15b+4=25.6
15b + 4.6 = 25.6
15b = 25.6 - 4.6
15b = 21
b = 21/15
Test:
0.6 + 15*21/15 + 4 = 25.6
06 + 21 + 4 = 25.6
