Answer:
813 = 800 + 10 + 3 = (8 ) + ( 1 ) + ( 3 )
Step-by-step explanation:
i) 813 = 800 + 10 + 3 = (8 ) + ( 1 ) + ( 3 )
Answer:
1. equal
2. add to 180
3. equal
4. add to 180
Step-by-step explanation:
as 1 and 3 are linear pairs
2 and 4 are vertically opposite angles
Answer:
you need to divide 1,256 by 8 which, is 157 seconds
Since both equations equal Y, set them equal to each other and solve.
3x -1 = -2x +9
Add 2x to each side:
5x - 1 = 9
Add 1 to each side:
5x = 10
Divide both sides by 5:
x = 10/5
x = 2
Now replace x with 2 and solve for y:
y = 3(2) -1 = 6-1 = 5
x = 2, y = 5 (2,5)
