Answer:
u = 20, v = 1
Step-by-step explanation:
Here, we can assume that the triangles are congruent for the purposes of solving the problem. Because they are congruent, by the HL right triangle congruency theorem, the hypotenuse and leg of each triangle have to be the same.
Therefore:
[tex]v+23=u+4\\19v+41=2u+20[/tex]
Now, you can simply solve the system of equations for v and u.
I will solve by substitution:
[tex]v+23=u+4\\v=u-19[/tex]
Now, plug that into the other equation:
[tex]19(u-19)+41=2u+20\\19u-361+41=2u+20\\19u-320=2u+20\\17u-320=20\\17u=340\\u=20[/tex]
Finally, plug that back into the first equation:
[tex]v+23=20+4\\v+23=24\\v=1[/tex]
u = 20, v = 1
Expand the following expression.

A phone company charges $25.00 a month for 500 minutes.
Every minute over 500 cost $0.75. If a customer uses 530
minutes how much will their monthly bill amount to?
Answer:
$47.50
Step-by-step explanation:
75 times 30 is 2,250, so then we put back the decimal and its 22.50, add that to 25.00, your answer is 47.50
3y + 2 = 4x , x+ 5y = 3 what is the solution to the system of equations shown above? (in fraction form)
Answer:
19/23, 50/23
Step-by-step explanation:
We can take the first equation and isolate the x:
x + 5y = 3 ⇒ -5y ⇒
x = 3 - 5y.
Then we can substitute the x in the first equation by this:
3y + 2 = 4(3-5y) ⇒
3y + 2 = 12 - 20y ⇒ +20y
23y + 2 = 12 ⇒ -2
23y = 10 ⇒ ÷23
y = [tex]\frac{10}{23}[/tex]
Then we can add the value of y into the equation equaling x we made:
x = 3 - 5([tex]\frac{10}{23}[/tex]) ⇒
x = 3 - [tex]\frac{50}{23}[/tex] ⇒
x = [tex]\frac{19}{23}[/tex]

Five ballet tickets and 3 musical tickets cost $370.00. 3 musical tickets cost $120. All ballet tickets cost the same and all musical tickets cost the same. What is the ratio of the cost of a ballet ticket to the cost of a musical ticket in simplest form?
Answer:
$50
Step-by-step explanation:
$370 - $120 = $250 ( 5 ballet tickets )
$250 divided by 5 tickets is $50 per ticket
Ratio is 50:40 or 5:4 simplified

Line c passes through points (4, 8) and (1, 13). Line d is parallel to line c. What is the slope of line d?
Does the point (2, 5) satisfy the equation y = x + 3?
yes
no
Answer:
YES
Step-by-step explanation:
You just need to plug in the numbers
x=2
y=5
5=2+3
5=5
So it is yes.
A scrapbooking store is selling rubber stamps for four dollarsand $4.95 each. The total sales F(n) is a function of the number of rubber stamps n sold
A. Identify the independent and dependent variables
B. What values of the domain and range make sense for this situation? explain
C. Write a function to represent the total sales. Then determine the total sales for five stamps
A. Independent variable: number of rubber stamps n sold. Dependent variable: F(n), the total sales.
B. Only whole numbers. It is impossible to have negative and/or fractional stamps.
C. F(n) = $4.95n, which is 4.95 times n.
So, plugin 5 for n
[tex]f(5)= \$4.95(5)[/tex]
F(n) = $24.75
Which of the following lines have a y intercept of (0,2)? Choose all that apply
a. 3x - 7y = -14 b. y - 4 = -1/4 (x+4) c. y + 5 = 3 (x+2) d. y = -7x + 2
Answer:
A and D
Step-by-step explanation:
a.
3x - 7y = -14
-7y = -3x -14
y = 3/7x + 2
b.
y - 4 = -1/4 (x + 4)
y - 4 = -1/4x -1
y = -1/4x + 3
c.
y + 5 = 3 (x + 2)
y + 5 = 3x + 6
y = 3x + 1
d.
y = -7x + 2
Bacteria colonies can triple in size every 4 days. If you start with 150 bacteria microorganisms, how large would the colony be after 16 days? First, complete the equation: Future Amount = 150(1+[?]
Answer:
But notice that the colony tripled 4 times in 16 days, or it tripled 16 / 4 = 4 times.
Step-by-step explanation:
150 x 3 x 3 x 3 x 3 = 150 x 34 = 150 x 81 = 12,150.

solve for x, find the measure of all angles hurryyyyyy!
Answer:
Step-by-step explanation:
Well the first fact is that you can solve H and J with 1 equation. Two remote (unconnected to) one of the exterior angles when summed, equals the unconnected exterior angle.
H + j are not connected to the exterior angle at I.
Put more directly
2x + 3x = 150 Combine
5x = 150 Divide by 5
x = 150/5
x = 30
So H = 2 * 30 = 60
and J = 3*30 = 90
All triangles have interior angles that add up to 180
We have already accounted for 150.
JIH + 150 = 180 Subtract 150
jIH = 180 - 150 = 30
Summary
x = 30
JIH = 30
H = 60
J = 90
