Answer:
a) x = 5
b) x = 12
Step-by-step explanation:
x + 3 = 8
Subtract 3 on both sides.
x = 8 - 3
x = 5
x - 5 = 7
Add 5 on both sides.
x = 7 + 5
x = 12
Answer:
35
Step-by-step explanation:
To find his total score in the quiz, we need to add all the scores he had in successive rounds.
This gives a value of; 25 + (-5) + (-10) + 15 + 10 = 25-5-10+15+10 = 25 + 10 = 35
Thus his total score at the end is 35
The computation shows that the time taken is 120 minutes.
<h3>How to illustrate the information?</h3>
From the information, Andrew is riding his bike and he biked a distance of 14 miles at a rate of 7 miles per hour.
Therefore, time taken for 14 miles will be:
= 14/7
= 2 hours
= 2 × 60 = 120 minutes
The time taken is 120 minutes.
