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
-2m+4m+5=3
(-2m+4m)+(5)=3
2m+5=3
2m+5-5=3-5
2m=-2
2m/2=-2/2
m=-1
Answer:
x=1; y=2; z=3
Step-by-step explanation:
Rearrange for convince:
2y-4z+6x = -2
-4y+2z-3x=-5
-6y+3z+4x=1
Now we take to pairs and eliminate the same var.:
2y-4z+6x = -2 *2
-4y+2z-3x=-5
and
-4y+2z-3x=-5 *-3
-6y+3z+4x=1. *2
We get:
4y-8z+12y=-4
-4y+2z-3x=-5
= -6z+9x=-9
and
12y-6x+9x=15
-12y+6x+8x=2
= 17x=17
We now know x = 1, so z is:
-6z+9=-9
-6z=-18
z=3
Let’s grab the first formula and find y:
6+2y-12=-2
6+2y=10
2y=4
y = 2
90 times bigger :) hope this helps !
I think that the missing value is 16m.
I just multiplied two other numbers with 20 and 20 x 16 x 16 = 5120
I hope this was right.
