Funny Number.

Answer: x = 81, y = 17

Step-by-step explanation:

x + y = 98

x/y = 4/13/y

x/y = 4y + 13/ y

x = 98 - y

(98 - y) / y = (4y+ 13) / y

Therefore

98 - y = 4y + 13

Collect like terms

-4y - y = 13 - 98

-5y = -85

Divide both sides by-5

y = 17

x = 98 - y

x = 98 - 17

x = 81

The two numbers​ x and y are 81 and 17 respectively.

Quotients are the number that is obtained by dividing one number by another number.

Dividend ÷ Divisor = Quotients

Given that the sum of two numbers is 98.

Let x and y be the two numbers

x + y = 98

Thus, the larger number is divided by the smaller quotient is 4 with a remainder of 13.

x/y = 4/13/y

x/y = 4y + 13/ y

x = 98 - y

(98 - y) / y = (4y+ 13) / y

Therefore,

98 - y = 4y + 13

Collect like terms;

-4y - y = 13 - 98

-5y = -85

Divide both sides by-5;

y = 17

x = 98 - y

x = 98 - 17

x = 81

Therefore, the two numbers​ x and y are 81 and 17 respectively.

Answer:

2

Step-by-step explanation:

the theorum you need for this is c^2 = a^2 + b^2, but because you have sides a and c, you need to work backwards.

Start by isolating b^2 in the equation.

c^2 = a^2 + b^2

        -a^2

c^2 - a^2 = b^2

b needs to not be squared, so take the square root of both sides

[tex]b = \sqrt{\sqrt{29}^{2} - 5^{2}[/tex]

Step-by-step explanation:

2x + 15 = 43 - 5x

2x + 5x = 43 - 15

7x = 28

x = 28/7

x = 4

Answer:

x = 4

Step-by-step explanation:

Step 1: Simplify both sides of the equation

2x +15 = 43 - 5x

2x +15 = 43 + - 5x

2x +15 = - 5x + 43

Step 2: Add 5x to both sides

2x + 15 + 5x= - 5x + 43 + 5x

7x +15 = 43

Step 3: Subtract 15 from both sides.

7x +15 -15 = 43 - 15

7x = 28

Step 4: Divide both sides by 7.

7x/7 = 28/7

Therefore the X = 4
