Answer:
1, 2, 5, 12, 13
Step-by-step explanation:
∠1 = 90 is given, which is a right angle
∠3 = 90 as well because ∠1 and ∠3 are vertically opposite
∠3 = ∠8, because ∠1 and ∠8 are same side exterior angles, which are the same
Therefore ∠3 must be congruent to ∠8

Alexa took a test and lost 3 points for each of the 7 questions she got wrong. She earned an additional 5 points for answering a bonus question correctly. How many points did Alexa receive or lose overall?
Answers
Answer:
Alexa lost 16 points overall
Step-by-step explanation:
To determine whether Alexa had a net receipt or loss of points, we will fine the total points received or lost, and find the difference:
points lost:
3 point for each of the 7 questions she answered wrong
lost point = 3 × 7 - 21 points
Points received:
5 points for answering a bonus question
point received = 5 point
The points lost (21) is greater than the points received (5), hence, there was a net loss. The net loss is calculated as follows:
points lost - points received
= 21 - 5 = 16
∴ Alexa lost 16 points overall

Answer:
[tex]\huge\boxed{\text{96 students}}[/tex]
Step-by-step explanation:
In order to find how many students stay back for Chess Club, we want to find 12% of 800.
To do this, we can set up a percentage proportion.
[tex]\frac{12}{100} = \frac{x}{800}[/tex]
We can now solve for x by cross multiplying.
[tex]800 \cdot 12 = 9600\\9600 \div 100 = 96[/tex]
So, 96 students attend Chess Club on Wednesdays.

Josh bought 3 bottles of grape juice and 5 bottles of water for a total of $14.50. Mary bought 2 bottles
of grape juice and 3 bottles of water for a total of $9.00. How much does the grape juice cost and the water?
Answers
Answer:
Bottle of water = $2Bottle of grape juice = $1.50Step-by-step explanation:
Grape juice = gWater = wEquations:
3g + 5w = 14.502g + 3w = 9.00Subtract the 3 times the second equation from the twice the first:
2*(3g + 5w) - 3(2g + 3w) = 2*14.50 - 3*9.006g + 10w - 6g - 9w = 29 - 27w = 2Then, finding g:
3g + 2*5= 14.503g = 14.50 - 103g = 4.5g = 1.50On Saturday morning 350 concert tickets went on a sale. Every 5 min 25 tickets were sold. Determine whether the number the number of remaining tickets is proportional to time in minutes.
Answers
Answer:
the number of tickets remaining is inversely proportional to the time in minutes:
number of tickets remaining = total amount of tickets - (25 tickets sold per minute x time in minutes) = 350 - 25T
Step-by-step explanation:
for example:
after 5 minutes, the number of tickets remaining = 350 - (25 x 5) = 225 tickets
after 10 minutes, the number of tickets remaining = 350 - (25 x 10) = 100 tickets
after 14 minutes, the number of tickets remaining = 350 - (25 x 145) = 0 tickets

Find a point-slope form for the line with slope 1/5 and passing through the point (-4,-9).
Answers
Answer:
y + 9 = [tex]\frac{1}{5}[/tex](x + 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = [tex]\frac{1}{5}[/tex] and (a, b) = (- 4, - 9) , thus
y - (- 9) = [tex]\frac{1}{5}[/tex](x - (- 4) ) , that is
y + 9 = [tex]\frac{1}{5}[/tex](x + 4)

Step-by-step explanation:
Adult tickets to a musical cost $15 and children's tickets cost $8. A total of 725 tickets were sold which brought in a total of $8775.
How many of each type of ticket were sold?
State the equation used to solve, along with both answers.
Answers
Given:
Cost of adult's ticket = $15
Cost of children's ticket = $8
Total tickets = 725
Total sales = $8775
To find:
The number of each type of ticket were sold.
Solution:
Let x be the number of adult tickets and y be the number of children's ticket.
Total tickets : [tex]x+y=725[/tex] ...(i)
Total sales : [tex]15x+18y=8775[/tex] ...(ii)
Multiply equation (i) by 15.
[tex]15x+15y=10875[/tex] ...(iii)
Subtract (iii) from (ii),
[tex]15x+18y-15x-15y=8775-10875[/tex]
[tex]3x=-2100[/tex]
[tex]x=-700[/tex]
Putting x=-700 in (i), we get
[tex]-700+y=725[/tex]
[tex]y=725+700[/tex]
[tex]y=1425[/tex]
Therefore, the number of adult tickets is -700 and number of child tickets is 1425.
Note: The number of tickets cannot be negative. So, there must be some error in the question.

Make & the subject of the
Formula
6x ta=5(x+t)
What is the answer please
Answers
6x+a = 5(x+t) Expand the bracket
6x+a = 5x+5t Subtract the least x’s (so 5x)
x+a = 5t Subtract a to make x the subject
x = 5t-a
Answer:
x = 5t - a
Step-by-step explanation:
The problem deals with making a variable the subject of the formula in the expression.
Given expression:
6x + a = 5(x + t)
We are to make x the subject of the formula in the expression
Solution:
6x + a = 5(x+t)
On the right hand side, expand the parentheses and distribute the term outside;
6x + a = 5x + 5t
Bring the term desired to be the subject to one side by adding (-5x) to both sides;
6x + (-5x) + a = 5x + (-5x) + 5t
x + a = 5t
Now add (-a) to both sides
x + a + (-a) = 5t + (-a)
x = 5t - a
