Answer:

4x + 15

Step-by-step explanation:

Let the age of Khairul's uncle y.

From the question given above, the following were obtained:

Khairul's age = x years

In 5 years time:

Khairul's age = x + 5

Khairul's uncle age = y + 5

But from the question given above,

Khairul`s uncle will be 4 times as old as what khairul will be in 5 years. This can be written as follow:

y + 5 = 4(x + 5)

Clear bracket

y + 5 = 4x + 20

Subtract 5 from both side

y + 5 – 5 = 4x + 20 – 5

y = 4x + 15

Therefore, Khairul's uncle present age is 4x + 15

Answer:

<h2>y= 4x+15</h2>

Step-by-step explanation:

This problem tests our ability to express word problem using equation

Given data

Khairul age = x years

let the uncle's age be y

in five years time, Khairul will be = x+5

in five years time, the uncle will be = y+5

 

hence Khairul uncle's age  is  

y= 4(x+5)

y=4(x+5)

y=4x+20

hence the uncles current age is

y+5=4x+20

y= 4x+20-5

y= 4x+15

Lapatulllka [165]

Answer:

  • A, C, E

Step-by-step explanation:

<u>Options:</u>

A. m∠C + m∠E = m∠A

  • Correct. Exterior angle equals to sum of non-adjacent interior angles.

B.   m∠D + m∠F = m∠B

  • Incorrect. Exterior angles have greater value.

C. m∠B + m∠C + m∠E = 180°

  • Correct. Interior angles of a triangle sum to 180°

D. m∠B + m∠C + m∠D = 180°

  • Incorrect. Angles C and D sum to 180°

E. m∠A + m∠ B = m∠E + m∠F

  • Correct. Both sides of equation refer to straight angle.

F . m∠B + m∠C + m∠ E = m∠A + m∠D + m∠F

  • Incorrect. Some of interior angles is not equal to sum of exterior angles.

Maria and Katy each have a piece of string. When they put the two pieces of string together end to end, the total length is 84in
Serga [27]

Answer: the length of Maria's piece of string is 45 inches.

the length of Katy's piece of string is 39 inches

Step-by-step explanation:

Let x represent the length of Maria's piece of string.

Let y represent the length of Katy's piece of string.

When they put the two pieces of string together end to end, the total length is 84inches. This means that

x + y = 84 - - - - - - - - - - - -1

Maria's string is 6 inches longer than Katy's. This means that

x = y + 6

Substituting x = y + 6 into equation 1, it becomes

y + 6 + y = 84

2y + 6 = 84

2y = 84 - 6 = 78

y = 78/2 = 39

x = y + 6 = 39 + 6

x = 45
