Answer
5
Step-by-step explanation:
8n+10=50
-10 -10
8n=40
8n/8 = 40/8
n= 5
She will be able to buy 5.
DOUBLE CHECK:
8(5)+10=50
40+10=50
50=50
Answer:
If two lines are parallel, then they have the same gradient.
Step-by-step explanation:
L is y=3x-2
L*2 is 3y-9x+5=0
The gradient for the first equation is 3
We need to rearrange the second equation and see if it has the same gradient as the first equation.
L*2 is 3y-9x+5=0
3y = 9x - 5
L*2 y = 3x - 5/3
As you can see, once you rearrange and simplify the equation, the second line has the same gradient as the first equation.
So that means these two lines are parallel
Hey there!
The answer would be B. y = 1.25x
If each pound is $1.25 and you get 4 pounds then that would equal to $5.00 or y.
Hope this helps !
