Any help would be appreciated(brainly for best answer)
Simora [160]

Answer:

b.

m<1 = 80 degrees because of the alternate angles rule.

m<2 = 100 degrees because angles on a straight line equals 180 degrees.

c.

m<1=75 degrees because again of the alternate angle rule.

m<2= 60 because that angle is equal to diagonally upper angle (I'll call it Z) and that angle would equal 60 because 180-120=60

Step-by-step explanation:

You really didn't need to do such complex math. If you want me to explain it more in detail, please let me know.

Winton was givin $14 to spend at a school fair he spent 3/7 playing games how much money is lift
Ksivusya [100]
<h3><u>Question:</u></h3>

Winton was given $14 to spend at a school fair he spent 3/7 playing games how much money is left

<h3><u>Answer:</u></h3>

Amount left with winton is $ 8

<h3><u>Solution:</u></h3>

Given that Winton was given $14 to spend at a school fair

He spent \frac{3}{7} playing games

To find: money left with Winton

From given information,

Money given to Winton = $ 14

Amount spent on games = \frac{3}{7}

Thus we can say,

Amount spend on games = \frac{3}{7} of total money he has

\rightarrow \frac{3}{7} \times 14 = 3 \times 2 = 6

Thus he spend $ 6 on playing games

<em><u>Money left with Winton:</u></em>

Money left = total money he had - money spent on playing games

Money left = 14 - 6 = 8

Thus amount left with winton is $ 8

True or false. If a is any odd integer, then a^2 + a is even. Explain this.
Ainat [17]

Answer:

True.

Step-by-step explanation:

We can represent an odd number by 2n + 1 where n = 0, 1, 2, 3, 5 etc.

Substituting:

a^2 + a = (2n + 1)^2 + 2n + 1

=  4n^2 + 4n + 1 + 2n + 1

= 4n^2 + 6n + 2

= 2(2n^2 + 3n + 1)

which is even because any integer multiplied by an even number is even.

This is also true if we use a negative odd integer:

We have 4n^2 + 4n + 1  - 1 - 2n

= 4n^2 + 2n

=  2(2n^2 + n(.
