3x+2y=11 ---(1)
x+4y=2 ---(2)

(1)*2; 6x+4y=22 ---(3)
(3)-(2); 5x=20
x=4
so 4+4y=2
4y=-2
y= -1/2
then (x,y) = (4,-1/2)

Danny binge watches four TV shows. His viewing habits include:
irinina [24]

Answer:

Danny will watch all of them on the same day again on August 31

Step-by-step explanation:

Here, we have a word problem.

The shows and frequency of watching are;

           

Show A                                   Every 2 days

Show B                                   Every 3rd day

Show C                                   Every 5th day

Show D                                   Every 10th day

Danny watched all four shows on August 1, therefore, the day he will watch all  four shows can be found by finding the Lowest Common Multiple, LCM of the frequency of his watching each of the shows. That is, the LCM of 2, 3, 5 and 10

Therefore we have, since 10 is the highest frequency and 3 is not a factor of 10, then the LCM that applies to 3 and 10 is 3×10 = 30.

Since the other frequencies are also a factor of 30, then the LCM of 2, 3, 5, and 10 is 30

Therefore, Danny will watch all four shows again on the same day again in 30 days after August 1. That is August (1 + 30) = August 31.

Alexxx [7]

Answer:

angle 1 and angle 2 are supplementary angles

Step-by-step explanation:

When the base of the angles forms a straight line, the sum of the angles is 180°. That's the definition of supplementary angles.

Complementary angles form a right angle. The sum of complementary angles is 90°

<em>A slightly silly way to remember Complementary angles: The two angles look at each other and compliment each other saying, "You look all right to me!"</em>

<em>"</em><em>Yes,</em><em> </em><em>we </em><em>are </em><em><u>so </u></em><em><u>right</u></em><em> </em><em>together</em><em>!</em><em>"</em>

My mother is 12 years more than twice my age.after 8 years she will be 20 years less than three times my age...find my age and m
Mnenie [13.5K]
You are correct for the first part, you would be 16 and your Mom would be 44. After 8 years, you would be 24 and your mother would be 52. You solve the second part by adding 8 to 16 which equals 24. Then multiply 24 times 3 which equals 72. Lastly, subtract 20 from 72 to find your mother's new age. Which would be 52.

Hope this helps !

Given: EG - diameter m arc FG =41°, m arc EH =53° Find: m∠E, m∠GPF
barxatty [35]

Answer: m∠E = 20.5°

              m∠GPF = 47°

Step-by-step explanation: An inscribed angle is an alge formed with its vertex on the circle. Its relation with arc is that the measure of an inscribed angle is half the measure of the intersected arc. For that reason:

m∠E = \frac{arcFG}{2}

m∠E = \frac{41}{2}

m∠E = 20.5°

Angle in F is:

m∠F = \frac{arcEH}{2}

m∠F = \frac{53}{2}

m∠F = 26.5°

The angle GPF is external to the triangle EPF, so the angle can be found by the following definition: The measure of an external angle of a triangle equals the sum of the non-adjacent angles, i.e.:

m∠GPF = m∠E + m∠F

m∠GPF = 20.5 + 26.5

m∠GPF = 47°

Ayesha works as a real estate agent. Her annual gross salary is $28,000. From this, she must pay 20% income tax on anything earn
Lady bird [3.3K]

Answer:

Step-by-step explanation:

Annual gross salary = $28000

Income tax = 20% on anything above $15000

So she's taxable for $5000

Rent loan = $140 per month = $140 * 12= $1680 per annum

Tax deductible per annum = 20% of $5000

20 / 100 * $5000 = $1000

Total amount she takes home per annum =

Gross salary per annum - tax - loan =

($28000 - $1000 - $1680) = $25,320

Ayesha takes home $25,320 home annually.
