Answer: Total cost would be $40, and multiplication expression would be

$8\times 5\\\\=\$40$

Step-by-step explanation:

Since we have given that

Number of his friend = 7

Including him, number of persons = 7+1 = 8

Cost of each ticket = $5

We need to find the total cost.

So, Total cost would be

$8\times 5\\\\=\$40$

Hence, total cost would be $40, and multiplication expression would be

$8\times 5\\\\=\$40$

Answer (x,y) (3, -2)

Explanation:
using the
substitution method
y
=
x
−
5
→
(
1
)
y
=
−
2
x
+
4
→
(
2
)
since both equations are expressed in terms of x we

can equate them
⇒
x
−
5
=
−
2
x
+
4
add 2x to both sides
2
x
+
x
−
5
=
−
2
x
+
2
x
+
4
⇒
3
x
−
5
=
4
add 5 from both sides
3
x
+
5
−
5
=
4
+
5
⇒
3
x
=
9
divide both sides by 3
3
x
3
=
9
3
⇒
x
=
3
substitute this value in
(
1
)
y
=
3
−
5
=
−
2
As a check
substitute these values into
(
2
)
right
=
−
6
+
4
=
−
2
=
left
⇒
point of intersection
=
(
3
,
−
2
)
