Answer:

Step-by-step explanation:

they are alternative exterior angles meaning they are equal.so you can solve by doing

7x-40=5x+10

isolate the terms by adding like terms. ( add 40 from the left side of the equation to the right.)

so it would look like this.

7x=5x+10+40. (the 40 was negative on the left side so you have to do the inverse to move it) do the same with the 5x.

now you have

2x=50. divide 50 by 2 to get your final answer .

Its parallel so they are equal
7x-40=5x+10

You and 3 friends go to the movies. Each movie ticket costs $6.25. If your mom gave you $20.00 and you bought popcorn for $3.50,

Sedaia [141]

Answer:

$Change = \$10.25$

Step-by-step explanation:

Given

$Individuals = 4$ <em>(You and 3 friends)</em>

$Total = \$20.00$

$Movie = \$6.25$ per individual

$Popcorn = \$3.50$

Required

Determine the change

First, we need to determine the total amount spent on movie ticket.

The question does not state whether I pay for my friend's ticket.

So, we'll work on what is obvious.

i.e

$Amount\ Spent\ on\ Ticket = \$6.25$

Add this amount to the amount spent on popcorn

$Amount\ Spent =\$6.25 + \$3.50$

$Amount\ Spent =\$9.75$

To get the Change, we have to deduct the total amount spent from the amount given by mom

$Change = \$20 - \$9.75$

$Change = \$10.25$

Hence:

The change is $10.25

Question 2 (Essay Worth 10 points)

Strike441 [17]

Answer:

(a) $f(2) = 81$

(b) $g(2) = 83$

Step-by-step explanation:

Given

$f(x) = 0.5x + 80$

$x \to g(x)$

$1 \to 81$

$2 \to 83$

$3 \to 85$

Solving (a): f(2)

We have:

$f(x) = 0.5x + 80$

$f(2) = 0.5*2+80$

$f(2) = 1 + 80$

$f(2) = 81$

Solving (b): g(2)

From the table:

$g(x) = 83$ when $x = 2$

So:

$g(2) = 83$

Solving (c): Which is greater f(2) or g(2)

In (a) and (b),

$f(2) = 81$

$g(2) = 83$

Hence, test average for maths class is greater
