Solve 3x−5 = 9:
Add 5 to both sides, to isolate 3x on the left side: 3x = 5+9 = 14
Solve this for x: x = 14/3
Answer=C
The first step in estimating is to round the numbers into simpler numbers so that we can easily do the math in our head...
312.21 becomes 300
59.113 becomes 60
300÷60=5
Answer=C
So a circle is divided into 360 equal degree,so that a right angle ie 90 degree
Answer:
13 ft
Step-by-step explanation:
- (Given)
- (Given)
- Perpendicular dropped from the center of the circle to the chord bisects the chord.
- Let the be r ft.
- Radius of the circle, perpendicular to the chord and half of chord forms a right triangle where r represents the hypotenuse. Thus, by Pythagoras Theorem:
For this case, the first thing we must do is define a variable.
We have then:
x: additional amount of weight that Li can add.
We write now the inequality that represents the problem.
We have then:
Answer:
An inequality that can be used to determine how much more weight can be added to the suitcase without going over the 50-pound weight limit is:
