Answer:
x = 6
Step-by-step explanation:
5x-3 = 2x+15
<h3>i) move 2x to the left-hand side and change its sign</h3>
5x-2x-3 = 15
<h3>ii) move -3 to the right-hand side and change its sign</h3>
5x-2x = 15+3
<h3>iii) collect like terms</h3>
3x = 15+3
<h3>iv) add the numbers</h3>
3x = 18
<h3>v) divide both sides of the equation by 3</h3>
Answer:
Step-by-step explanation:
The circumference is the distance around a complete circle: in essence, the perimeter of a circle. The formula to find the circumference of a circle is the following:
Where (d) represents the diameter, the largest cord that can be drawn in a circle, it goes from one end to another, passing through the center of the circle. The parameter (
) represents the number (3.1415...). However, one is given a semicircle, thus one must divide the result in two, and then add the value of the diameter to find the perimeter of the given object. Therefore the equation for the circumference of this circle is as follows:
Substitute in the given value,
Simplify,
Answer:
82.125
≈82.12 ( am not sure if it need to be estimated )
Step-by-step explanation:
1 hr -> 10.95
30m-> 5.475
10.95x7=76.65
76.65+5.475=82.125
≈82.12 ( am not sure if it need to be estimated )
For the number before x you would look for the rise over the run. in this case you can see that there is an intersection at (-2,0) and (0,1) you find the difference ox each so you have 2/1 or just 2 you can tell that the line is going up so it is positive. for the addition part look at where the y intercept is in this case it is at positive one. this makes your equation y=2x+1
