Subtract equation ( ii ) from equation ( i ) :

Remember that the sign of each term of the second expression changes i.e equation ( i ) now becomes -4x -3y = -20

[tex] \tt{ \cancel{4x }+ 2y = 14}[/tex]

[tex] \tt{ \cancel{ - 4x} - 3y = - 20} [/tex]

[tex] \tt{ - y = - 6}[/tex]

⟿ [tex] \tt{ \boxed{ \tt{y = 6}}}[/tex]

Again , Substituting the value of y in equation ( ii ) :

⟿ [tex] \tt{4x + 2 \times 6 = 14}[/tex]

⟿ [tex] \tt{4x + 12 = 14}[/tex]

⟿ [tex] \tt{4x = 2}[/tex]

⟿ [tex] \boxed{ \tt{x = \frac{1}{2}}} [/tex]

[tex] \red{ \boxed{ \boxed{ \tt{Our \: final \: answer : x = \frac{1}{2 } \: and \: y = 6}}}}[/tex]

Step-by-step explanation:

Include a Claim, Evidence, Explanation, and Conclusion for full credit.

Cells were obtained from a patient with a viral infection. The DNA extracted from these cells consisted of two forms: double-stranded human DNA and single-stranded viral DNA. The base composition of these two forms of DNA are shown in the image.

Construct an argument based on evidence to determine which form was the viral DNA and which form was the human DNA.

Answer:

1) 13 ft

Step-by-step explanation:

1) 13+8=21 which is greater than 15. Would be a triangle.

2) 7+8=15   This would be a single line, not a triangle.

3) 3+8<15   This would be a single line, not a triangle.

2) 15+8=23   This would be a single line, not a triangle.

Answer:

n-7>-4

n-7+7>-4+7

n>-4+7

n>3

Answer:

Step-by-step explanation:

look the inequality is the variable. 7-4=3. That means n>3

Answer:

10/16

Step-by-step explanation:

I looked at the 5 and looked at every other number and you can't multiply evenly with those other numbers. You can only do 5x2 which will get you ten. But that won't work for the other numbers.

Hope this helps :)

Something that the five major world religions (Christianity, Judaism, Buddhism, Hinduism and Islam) have in common is a sense of community. A sense of community provides group cohesion and identity, as well as a way for rituals and traditions to be passed down from generation to generation.

Answer:

n= -3.5

Step-by-step explanation:

n/7 - 12 = 5n +5

+12            +12

n/7 = 5n+17

*7      *7

n = (5n+17)*7

n = 35n + 119

-35n    -35n

-34n = 119

/-34     /-34

n = -3.5

Answer:

40 km/hr

Step-by-step explanation:

Given that:

Total distance covered in 3 hours = 60km

Speed during first 40 km = 16km/hr

Hence, time spent during the first 40 km ;

Recall:

Time = distance / speed

Time = 40 / 16

Time = 2.5 hours

Hence, speed required to cover the remaining (60 - 40) = 20km in (3 - 2.5) hours =0.5 hours

Speed = distance / time

Speed = 20 / 0. 5

Speed = 40 km / hr

Answer:

-17/-1 and 17 are the same so you are correct!

Step-by-step explanation:

in the fraction, -17/-1, you want to get rid of the negatives. in order to do that, you have to get rid of them on both the numerator and denominator! so the new fraction would be 17/1, and that would be simplified to just 17! so you are correct, i hope this helps!

Answer:

yes your cauculators correct, it is 17

Step-by-step explanation:

you need to divide the fraction since there are 2 negative numbers

Answer:

x < - 8

Step-by-step explanation:

Given

3(x + 1) + 11 < - 2(x + 13) ← distribute parenthesis on both sides

3x + 3 + 11 < - 2x - 26

3x + 14 < - 2x - 26 ( add 2x to both sides )

5x + 14 < - 26 ( subtract 14 from both sides )

5x < - 40 ( divide both sides by 5 )

x < - 8

Answer:

x<-8

Step-by-step explanation:

3x+14<-2x-26(combine and distribute)

3x+14-14<-2x-26-14(subtract 14 from both sides)

3x<-2x-40(add 2x to both sides)

5x<-40(divide both sides by 5

x<-8(this is your final answer)

Hope it helps!!

Answer:

She would get back 10.05

Step-by-step explanation:

Do 9.99 times three and you get 29.97 then do 14.99 times two and you get 29.98 then add them together to get 59.95. Next subtract 70.00 from 59.95 then you get how much change she needs back

Answer:

3

Step-by-step explanation:

It's decreasing by 3 each time, so the next number in the sequence would be 6 - 3, which is 3.

Answer:

3

Step-by-step explanation:

because each number is decreasing by 3 so the next one would be 3

Answer:

21°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

subtract the sum of the 2 given angles from 180 for the other angle

other angle = 180° - (90 + 69)° = 180° - 159° = 21°

Answer:

Well, the y axis is the up and down line of the graph. Therefore, if the translation says move up six, simply add six to the y axis (ex. -6, -10 move up six: -6, -4)! super simple, right? hope this helps!

Answer:

c = √18

Step-by-step explanation:

c² = 3² + 3² = 18

so c = √18 = 3√2 ≈ 4.24

Answer:

12.2

Step-by-step explanation:

Let C be the last angle c + 55° + 35° = 180° (sum of angles in a triangle)

C + 90° = 180°

C = 180° - 90°

C = 90°

Let c be the last side

Using the sine rule a/sinA = b/sinB = c/sinC

Using any of the other two sides,

10/sin55° = c/sin90°

c = 10/sin55° × sin90°

c = 10/0.8192 × 1

c = 12.21

c ≅ 12.2

Answer:

Answer:

(a+b)(2x−ab+a−b)+x(a−b)+x²

Step-by-step explanation:

I can't make a good explanation, so here's a graph.

Also, this wouldn't be a proportional relationship because of exponents on the last term.

This is really a parabola.
