Answer
D. -3x + 4(2x-6) + 5
Step-by-step explanation:
-3x has nothing attached to it so leave it alone
4 times 2x equals 8x and 4 times -6 equals -24
add 5
8x-3x=5x
-24 + 5 = -19
5x - 19
Ten thousands
if you're speaking of place value?
.........where 78 is the total girls and d is the number of girls in a group.
Find the polar coordinates in the usual way, then negate r and add 180° to θ.
You know that
... r = √(x² + y²)
... θ = arctan(y/x) . . . . . taking quadrant into account
The coordinates (r, θ) and (-r, θ+180°) specify the same point.
Answer:
Ahmed has more toffees
Ben has more chocolates
Step-by-step explanation:
Ahmed:
60% = 3/5
3/5 x 30 = 18
therefore out of 30, 18 are toffees.
30 - 18 = 12
therefore 12 are chocolates
Ben:
3/8 x 40 = 15
therefore out of 40, 15 are toffees
40 - 15 = 25
therefore 25 are chocolates
By the way I am not sure!
