Can you take a better picture. That would help to answer the question.
Answer:
420miles
Step-by-step explanation:
240/4=60MI/H
Oscar's speed is 240mi/4h = 60mi/h
How far he drives in 7 hours: 60mi/h * 7h = 420mi
The solution of the linear system is given by using an arithmetic operation. Then the value of b is 2.
<h3>What is the linear system?</h3>
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The linear equation is given below.
–12 + 3b – 1 = –5 – b
The value of b will be given as
Add b both sides, we have
–12 + b + 3b – 1 = –5 – b + b
–13 + 4b = –5
Add 13 on both sides, we have
13 – 13 + 4b = – 5 + 13
4b = 8
Divide both sides by 4, we have
b = 2
