Answer:-1/6
Step-by-step explanation:
-1/2 + (3/4times4/9)
-1/2 + (3/4 x 4/9)
-1/2 + (3x4)/(4x9)
-1/2 + 12/36
(18 x -1 + 1 x 12)/36
(-18+12)/36
-6/36=-1/6
The last one is not scientific notation because the 25.67 is greater than 10
Answer:
2. y = 7
3. x = 4
Step-by-step explanation:
Slope 0 is when the line is horizontal.. has a constant coordinate
(-5,7) lies on the line so the x-coordinate is 7
Equation: y = 7
A vertical line has all same x-coordinates.
Since (4,-2) is on the line, every point had x-coordinate of 4.
Equation: x = 5
Use the slope formula
Plug in the appropriate cords into the formula.
The slope of the line is -9/14.
Answer: 78 rupees
Explanation: since 10 pens cost 60 rupees you can divide 60 by 10 to get the cost of a single pen. The cost of a single pen is 6 rupees so you can multiply that by 13 to find the cost of the 13 pens.
10p=60
60/10=6
p=6
so
13x6=78
Hope this helped! :)
