<u>Given</u>:
Let the two numbers be x and y.
Two numbers multiply to be -7 and add to be -6.
This can be written in equation as,
and
<u>Value of the two numbers:</u>
Let us determine the value of the two numbers using substitution method.
Substituting in the equation , we get;
Simplifying, we get;
Thus, the values of x are x = 1,-7
When x = 1 , the equation becomes
When x = -7, the equation becomes
Therefore, the two numbers are 1 and -7
8% = 0.08
x = total sales.
Let's create an equation to help us solve this problem.
0.08x = 35
Divide both sides by 0.08.
x = 437.5
Answer D is correct.
He earns $44 dollars. he charges $2 dollars for every bag.
Divide by 4 if it has 4 equal sides and the answer is 13.5.
The airplane went 5195.33 km
Step-by-step explanation:
Distance = speed × time
The given is:
1. An airplane flies for 3.5 hours with a constant speed of 840 km/h
2. Then for another 3 hours 19 minutes with a constant speed of
680 km/h
We need the distance it traveled
For the first part
∵ The time is 3.5 hours
∵ The speed is 840 km/h
∵ Distance = speed × time
- Substitute the values of the speed and the time in the rule
∴ Distance = 840 × 3.5
∴ Distance = 2940 km
For the second part
∵ The time is 3 hours and 19 minutes
- We must change the minutes to hour
∵ 1 hour = 60 minutes
∴ 19 minutes = hour
∴ The time is hour
∵ The speed is 680 km/h
∴ Distance = 680 ×
∴ Distance = km
∴ The total distance = 2940 +
∴ The total distance = km
It went 5195.33 km
