Answer:
x=5, y=1
Step-by-step explanation:
Isolate x for 5x-3y=22
5x-3y=22
Add 3y to both sides
5x-3y+3y=22+3y
Simplify
5x=22+3y
Divide both sides by 5
5x/5=22/5+3y/5
Simplify
x=22+3y/5
Substitute x=22+3y/5
10*22+3y/5-4y=46
Simplify 10*22+3y/5-4y
10*22+3y/5=2(3y+22)
=2(3y+22)-4y
Expand 2(3y+22)
=6y+44-4y
Simplify 6y+44-4y
=2y+44
Isolate y for 2y+44=46
2y+44=46
Subtract 44 from both sides:
2y+44-44=46-44
Simplify
2y=2
Divide both sides by 2;
2y/2=2/2
Simplify;
y=1
For x=22+3*1/5 substitute y=1
y=22+3*1/5
22+3*1=25
=25/5
Divide the numbers;25/5=5
=5
x=5
The solutions to the system of equations are;
x=5, y=1
A population of llamas stranded on a desert island is decreasing due to a food shortage by 6% per year. If the population of llamas started out at 350, how many are left on the island 10 years later?
Answer:
189
Step-by-step explanation:
Given data
Initial population=350
Rate = 6%
TIme= 10 years
Let us apply the compounding expression
A=P(1-r)^t----------The negative sign is due to decreasing value
substitute
A= 350(1-0.06)^10
A=350(0.94)^10
A=350*0.5386
A=188.51
Hence the approximate population will be 189

Step-by-step explanation:
In the given diagram , TY is a tangent to the circle TVS . If <SVT = 48° and |VS| = |ST| . What is < VTY.
Answer:
84°Step-by-step explanation:
∠VTY is the tangent chord angle
Tangent chord angle is the half of the intercepted arc∠TSV is the inscribed angle.
Inscribed angle is the half of the intercepted arcSince both of the mentioned angles refer to same arc, they are of same value.
∠VTY = ∠TSVΔTVS is isosceles as VS = ST, therefore the opposite angles are same.
m∠T = m∠V = 48°The measure of angle S
m∠S = 180° - 2*48° = 84°The required angle
m∠VTY = 84°Answer:
∠VTY = 84°
Step-by-step explanation:
because ΔTSV is isosceles (ST = SV) then ∠VTS = ∠SVT = 48°
Then ∠VST = 84° (180 - 48 - 48 = 84)
Well, I'm going back to the picture is worth a thousand words again.
Sketch attached:
A line from S to the center bisects ∠VST into two 42° angles.
A line from T to the center forms a 42° angle with line ST.
48°-42° = 6° = angle from perpendicular line CTR to line VT.
90° - 6° = 84° for ∠VTY

HELP One angle of a regular hexagon measures (2x+10)°Find x
Answer:
x = 55
Step-by-step explanation:
total number of degrees in a 6-sided figure is (6-2)x180, which is 720°
720/6 = 120
Each angle of a hexagon measures 120°
2x+10 = 720
2x = 110
x = 55

QUESTION IN PIC
Neptune's average distance from the Sun is 4.503 × 109 km. Mercury's average distance from the Sun is 5.791 × 107 km. About how many times farther from the Sun is Neptune than Mercury
9514 1404 393
Answer:
Step-by-step explanation:
The ratio of distances is ...
Neptune distance / Mercury distance = (4.503×10^9)/(5.791×10^7)
= 450.3/5.791 = 77.76 . . . . cancelling factors of 10^7
Neptune is about 77.76 times as far from the Sun as Mercury is.

Brenda likes to swim when she is at her cottage. She swam 12 m north from her dock, and then 60 m east. How far will she have to swim if she wants to go directly back to the dock?
Answer:
72 m
Step-by-step explanation:
If Brenda is going 12m north and 60m east, that's a total of 72m because 12+60 = 72, so if Brenda wants to come directly back to the dock she will just have to follow her footsteps back 72m.
A handbag company had 5% of the market in 2011 in 2015 it had 23%.
(a) Write a linear equation expressing the percentage of the luxury handbag market y that the company had x years after 2000
Answer:
[tex]y = 0.045x -0.445[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1)=(11,5\%)[/tex] ---- in 2011
[tex](x_2,y_2)=(15,23\%)[/tex] --- in 2015
Required
Linear equation for x years after 2000
First, calculate the slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{23\% - 5\%}{15 - 11}[/tex]
[tex]m = \frac{18\%}{4}[/tex]
[tex]m = 4.5\%[/tex]
[tex]m = 0.045[/tex]
The equation for x years after 2000 is:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = 0.045(x - 11) + 5\%[/tex]
[tex]y = 0.045x - 0.495 + 0.05[/tex]
[tex]y = 0.045x -0.445[/tex]
