We can Split the Middle Term of this expression to factorise it.
In this technique, if we have to factorise an expression like
a
x
2
+
b
x
+
c
, we need to think of 2 numbers such that:
N
1
⋅
N
2
=
a
⋅
c
=
3
⋅
3
=
9
and,
N
1
+
N
2
=
b
=
10
After trying out a few numbers we get:
N
1
=
9
and
N
2
=
1
9
⋅
1
=
9
, and

is the factorised form for the expression.
Answer:
5x + 2y = 3280
x+y = 785
x = 785 - y
5*(785 - y) + 2y = 3280
3925 - 5y + 2y = 3280
3925 - 3280 - 3y = 0
645 = 3y
y=645/3=215
x=785-215 = 570
Adults - 570 tickets, childs - 215 tickets.
570*5 + 215*2 = 3280
570 adult and 215 child and 3,280 in total
if i could get brainliest that would be great
Answer:
All except the second one (angle g is not similar to angle r)
Step-by-step explanation:
Just look at the order of the letters. It it's the same, its similar.
Do you have any options to pick from
Answer:
The slope is .075 and the y intercept is -.125
Step-by-step explanation:
8y = .2(3x -5)
Distribute the .2
8y = .6x - 1
Divide by 8
8y/8 = .6x/8 -1/8
y = .075x -.125
This is in slope intercept form y= mx+b where m is the slope and b is the y intercept.
The slope is .075 and the y intercept is -.125
