Answer:
a = 29
b = 20
Step-by-step explanation:
2a - 1 = 57
+ 1 + 1
2a = 58
/ 2 / 2
a = 29
2a - 1 + 7b - 17 = 180
2 (29) - 1 + 7b - 17 = 180
58 - 1 + 7b - 17 = 180
57 + 7b - 17 = 180
7b + 40 = 180
- 40 - 40
7b = 140
/ 7 / 7
b = 20
The slope intercept form is always y= mx + b, where m represents the slope or inclination, and b the y intercept ( the point where the line cuts the Y axis)
then first case 10x +y = 3 is rewrited to y= -10x + 3
second case x- 2y =4. Is rewrited to -2y = -x + 4 it means y = -x/-2 + (4/-2)
third case 18 x + 3y = 6. Is rewrited to 3y = -18x + 6. Then y= (-18/3)x + (6/3)
There are only two numbers on the number cube greater than 4, which would be 5 and 6. So, that would be 2/6, or 1/3. The answer is C.
225 litres of fuel for 340 km
225/340 litres of fuel for 1 km
255/340 * 100 litres of fuel for 100 km
2550/34 = 1275/17 litres of fuel per 100 km(simplified)
update:1275/17 = 75 lol
What are two lines joining at one point?
The definition of intersecting lines can be called two lines that cross each other a only one point. This point is called the point of intersection.
