Answer:
(3, 11), because both lines pass through this point
Step-by-step explanation:
x = y - 8
y = 3(y -8) + 2
y = 3y - 24 + 2
y - 3y = -22
-2y = -22
y = 11
11 = x + 8
x = 11 - 8
x = 3
Answer :- (3,11)

The mass of 2 bags, which is filled by Lynn each with 2 kilograms 450 grams of sand, is less than 5 kilograms.
How to measure the weight?Weight measurement is the measurement of the heaviness of a object. The units of weight measurement are pounds, grams, kilograms etc.
There is total 1000 grams in one kilogram of weight measurement.
Lynn filled each of three bags with 2 kilograms, 450 grams of sand. There is total 1000 grams in one kilogram of weight measurement. Thus, the kilogram in 450 grams is,
[tex]x=\dfrac{450}{1000}\\x=0.45\rm\; kg[/tex]
Thus, weight in one bag is,
[tex]W=2+0.45\\W=2.45\rm\; kg[/tex]
The weight in two bags is,
[tex]2W=2.45+2.45\\2W=4.9\rm\; kg[/tex]
The weight of 4.9 kg is less than the 5 kilogram..
Thus, the mass of 2 bags, which is filled by Lynn each with 2 kilograms 450 grams of sand, is less than 5 kilograms.

Use either elimination or substitution.
y = x - 4
x + y = 6
Answer:
Since x = 3, y = 1 is the solution of
x – 4y + p = 0 …………….. (i)
2x + y – q – 2 = 0 …………… (ii)
So, x = 3, y = 1 must satisfy both (i) and (ii).
⇒ 3 – 4(1) + p = 0 ⇒ p = 1.
and 2(3) + (1) – q – 2 = 0 ⇒ q = 5
Since, 1 = – 4 + 5
∴ p = 1 = – 4 + 5
= q – 4
⇒ p = q – 4

The area of rectangle is ( 30x²y + 20xy ) cm² and its breadth is 10xy cm .Find its length.
Subtract the quotient when 20x⁴y² is divided by 5x³y from the product of 2x and 3y.
Step-by-step explanation:
1) The area of rectangle is ( 30x²y + 20xy ) cm² and its breadth is 10xy cm .Find its length....
= Solution ,
Length ( L ) = ?
breadth ( b ) = 10xy cm
area ( a ) = ( 30x² + 20xy )
Now ,
area ( a ) = l × b
or, ( 30x²y + 20xy ) = L × 10xy cm
[tex]or,\frac{30 {xy + 20xy}^{2} }{10xy} = l \\ [/tex]
[tex]or, \: l = 3 {x}^{2 - 1} + 2cm[/tex]
[tex]\boxed{\sf{l = (3x+2)cm}}[/tex]
2) Subtract the quotient when 20x⁴y² is divided by 5x³y from the product of 2x and 3y.
= Solution,
[tex] = \frac{20 {x}^{4} {y}^{2} }{5 {x}^{3} y} \\ [/tex]
[tex] = 4xy[/tex]
The product of 3x and 4y = 6xy

Daniel has a bag that contains pineapple chews, apple chews, and watermelon chews. He performs an experiment. Daniel randomly removes a chew from the bag, records the result, and returns the chew to the bag. Daniel performs the experiment 51 times. The results are shown below:
A pineapple chew was selected 21 times.
A apple chew was selected 12 times.
A watermelon chew was selected 18 times.
Based on these results, express the probability that the next chew Daniel removes from the bag will be a flavor other than watermelon as a decimal to the nearest hundredth.
The probability that the next chew Daniel removes from the bag will be a flavor other than watermelon is 0.65
How to determine the probability?The distribution of the fruits is given as:
Pineapple = 21Apple = 12Watermelon = 18The probability that the next chew Daniel removes from the bag will be a flavor other than watermelon is:
P = (Apple + Pineapple)/Total
This gives
P = (12 + 21)/(21 + 12 + 18)
Evaluate
P = 0.65
Hence, the probability that the next chew Daniel removes from the bag will be a flavor other than watermelon is 0.65

What is the compliment of an angle that measures 2x degrees?
Answer:
(90 - 2x)°
Step-by-step explanation:
complimentary angles sum to 90° , then
the compliment of 2x° is (90 - 2x)°
Answer:
(90 - 2x)°
Step-by-step explanation:
We say that two angles are complementary if their measures add up to 90°
The complement of an angle that measures 2x is the angle of measure
(90 - 2x)°
because 2x + (90-2x) = 90

What is the measure of each angle in Megan’s triangle?
m∠A =
°
m∠B =
°
m∠C =
°
Answer:
A, C and D are true statements.
Step-by-step explanation:
Megan constructed triangle ABC.
In Megan’s triangle, m∠A is represented by x°.
Therefore, ∠A = x°
For m∠B is 4 times greater than m∠A
Therefore, ∠B = 4x°
For m∠C is 30° less than 5 times m∠A.
Therefore, ∠C = 5x°-30°
ABC is a triangle.
Sum of all angles of a triangle is 180°. Angle sum property of triangle.
m∠A + m∠B + m∠C = 180°
x° + 4x° + 5x°-30° = 180°
x° = 15°
True Statements are:
A) m∠A = x°
C) m∠B = (4x)°
D) m∠C = (5x – 30)°
