Answer:
Size of each group = 
Step-by-step explanation:
Total number of paint brushes = x
Since each the three groups are equally sized, to get the number of paintbrushes in a group, we will have to divide the total number of paint brushes by 3
∴ We have, number of paint brushes in a group = 
=
this is also the same thing as saying 
×
This shows that the size of the new group is the same as the size of the original group
Answer:
Advance tickets-$15
Same-day tickets-$20
Step-by-step explanation:
let x be the cost of advance tickets and y cost of same-day tickets:
Given that there were 40 advance and 25 same-day tickets for a total of $1100:
#Make x the subject in i and substitute in ii:
Hence, advance tickets cost $15 each while same-day tickets cost $20 each.

2 result(s) for "f(x) = 4x³ - 10 g(x)
Answer:
The correct answer is 25
Step-by-step explanation:
It is given a quadratic equation,
x² – 8x = 9
<u>To find the number to be added</u>
The given equation be x² – 8x = 9
here we have to add (b/2)² - the square of half the coefficient of x,
Here b = -8
(b/2)² = (-8/2)² = -4² = 16
Add both side with 16
x² – 8x + 16 = 9 + 16
(x - 4)² = 25
(x - 4)² = 5²
Answer:
18x+y=-52
Step-by-step explanation:
we all know and love(being 100% sarcastic here)the standard form as
ax+by=c
y=-9(x+3)*2+2----This is weird and not so nice
so lets make it nice by distributing the 9::::
y=(-9x-27)2+2
and now the 2:
y=-18x-54+2
y=-18x-52
oops this is NOT in S.F we got to switch the -52 and y
52=-18x-y
-18 cant be neg. so we have to divide by -1 on both sides
-52=18x+y
18x+y=-52
HOPE THIS HELPS
