Mathematics
1 answer:
Ksivusya [100]3 years ago
4 0

Answer:

x=-3

Step-by-step explanation:

-2x2=-4

-4-16x-44=0

combine like terms (-4,-16)

-48-16x=0

move the 16x to the other side of the equal sign (add 16 since its -)

-48=16x

you need x alone so you need to divide by 16

-3=x

Juli buys a flat with 48 flowers. She was wants to plant them in equal rows of 5 flowers. How many rows can Juli plant? How many
miss Akunina [59]

Answer:

5 row, 3 left

Step-by-step explanation:

She has 48 flowers, 5 flowers one row

How many rows can she make? So divide

48/ 5

= 9.6

So she can only make 9 rows

The leftovers flowers are the flowers that didn't manage to make 5 per row

Therefore, if she can make 9 rows, in other words 9 x 5 = 45

45 flowers were able to be placed in a sequence of 5 per row

So the ones that are left is

48 - 45

= 3
