A larger number is twelve more
than a smaller. Their sum is
84. Find the numbers.​

Answers

Answer 1

Answer:  bigger number is 48 and smaller number is 36

Step-by-step explanation:

Answer 2

Answer:

The smaller number  ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48

Step-by-step explanation:

Let the larger number be = xLet the smaller number be = y

As the larger number is twelve more  than a smaller, so

x = y + 12

As the sum of larger and smaller numbers is 84, so

x + y = 84

now substituting x = y + 12 in th equation x + y = 84

x + y = 84

(y + 12) + y = 84

2y + 12 = 84

subtract 12 from both sides

2y + 12 - 12 = 84 - 12

2y = 72

divide both sides by 2

2y/2 = 72/2

y = 36

Thus,

The smaller number  ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48

Answer:

Some examples of linear equations in two variables are: 1.2s + 3t = 5, p + 4q = 7, πu + 5v = 9 and 3 = 2 x – 7y. Note that you can put these equations in the form 1.2s + 3t – 5 = 0, p + 4q – 7 = 0, πu + 5v – 9 = 0 and 2 x – 7y – 3 = 0, respectively.

Urgent. Please answer ASAP. Thanks guys!

Answers

Answer:

n= -9, t= -9

Step-by-step explanation:

1) -1/3(n+15)=-2

-1/3×n+-1/3×15=-2

-1/3×n -5= -2

-1/3 n-5+5= -2+5

-1/3×n=3

3/-1×-1/3×n=3/-1×3

n= -9

2) 46 = -6t -8

−6t−8=46

−6t−8+8=46+8

−6t=54

Divide both sides by -6

t=-9

Sum of two numbers = 15 (Addition)

Difference of two numbers =3 (Subtraction)

Find the two numbers.

What is the product of those two numbers? (Multiplication)

Answers

Answer:

The numbers are  x= 9 and y =6

The product of two numbers

x y  = 9 × 6 = 54

Step-by-step explanation:

Step(i):-

Let x and y are two numbers

Given that the sum of two numbers

 x + y = 15 ..(i)

Given that the difference of two numbers

x - y = 3 ..(ii)

adding (i) and (ii) , we get

x + y + x -y = 15 +3

  2 x = 18

    x =9

Step(ii):-

Substitute x = 9 in equation (i) , we get

x + y = 15

9 + y = 15

     y = 15 - 9

    y = 6

Final answer:-

The numbers are  x= 9 and y =6

The product of two numbers

x y  = 9 × 6 = 54

Solve and check
y = 3x - 10
y = 2x - 5

Answers

Answer:

This is the subtraction method

Y -3X = -10

(-Y -2x = -5)  -Y + 2X = 5

Y -3X = -10

-Y + 2X = 5

      -X = -5

X = 5  Now fill in the 5 for X and Y =  5

Answer:

x = 5, y = 5

or

(5, 5)

Step-by-step explanation:

they both equal y so they also equal each other.

3x - 10 = 2x - 5

3x - 2x = -5 + 10

x = 5

substitute x for 5

y = 3x - 10

y = 15 - 10

y = 5

edit, whops forgot to check

just plug the variables in with their values and see if it makes sense:

y = 2x - 5

5 = 2*5 - 5

5 = 10 - 5

5 = 5

since 5 does equal 5, the solution is correct.
