Maths P5 Test 1

1) The lengths of two adjacent sides of a parellelogram are x and y , then its perimeter =

X +y

X - y

2x + y

2(x + y)

The perimeter of a parallelogram is the sum of all its sides. In this case, we have two adjacent sides with lengths x and y. To find the perimeter, we add the lengths of these two sides, resulting in 2(x + y).

Explanation

The perimeter of a parallelogram is the sum of all its sides. In this case, we have two adjacent sides with lengths x and y. To find the perimeter, we add the lengths of these two sides, resulting in 2(x + y).

2) Add 5 to the 3 times of a number.=......

3x + 5

5 - 3x

3x -5

5x + x

The given question asks to add 5 to the 3 times of a number. In algebraic terms, this can be represented as 3x + 5, where x represents the unknown number. The expression 3x + 5 correctly represents the given information and provides the desired result.

Explanation

The given question asks to add 5 to the 3 times of a number. In algebraic terms, this can be represented as 3x + 5, where x represents the unknown number. The expression 3x + 5 correctly represents the given information and provides the desired result.

3) Suzan saved LE X and her father gave her LE 10. She will have ......

X - 10

X ÷ 10

X + 10

10 - X

After Suzan saved LE X, her father gave her an additional LE 10. Therefore, the total amount she will have is X + 10.

Explanation

After Suzan saved LE X, her father gave her an additional LE 10. Therefore, the total amount she will have is X + 10.

4) Subtracting 3 from double of the number x = ......, ,

X - 3

2x -3

3x + 2

2x + 3

The correct answer is 2x - 3 because the question states to subtract 3 from double of the number x. This can be represented as 2x - 3, where 2x represents double of the number x and -3 represents the subtraction of 3 from it.

Explanation

The correct answer is 2x - 3 because the question states to subtract 3 from double of the number x. This can be represented as 2x - 3, where 2x represents double of the number x and -3 represents the subtraction of 3 from it.

5) The perimeter of a square whose side length is L= ..............

4L

4 + L

(L+4)X2

L -4

The perimeter of a square is the sum of all its sides. In this case, the side length of the square is L. Since a square has four equal sides, the perimeter can be calculated by multiplying the side length by 4. Therefore, the correct answer is 4L.

Explanation

The perimeter of a square is the sum of all its sides. In this case, the side length of the square is L. Since a square has four equal sides, the perimeter can be calculated by multiplying the side length by 4. Therefore, the correct answer is 4L.

6) Add 4 to the half of a number

4 + 2x

2x +4

4x + 2

X +4 ½

The correct answer is X +4 ½ because the question states to add 4 to the half of a number. In the given options, only X +4 ½ represents adding 4 to half of a number, as it includes the fraction ½ which represents half. The other options either do not include the fraction or do not represent adding 4 to half of a number.

Explanation

The correct answer is X +4 ½ because the question states to add 4 to the half of a number. In the given options, only X +4 ½ represents adding 4 to half of a number, as it includes the fraction ½ which represents half. The other options either do not include the fraction or do not represent adding 4 to half of a number.

7) If we subtract 5 from the number X we get ......

X - 5

5x

X + 5

5 - x

Subtracting 5 from a number X can be represented as X - 5.

Explanation

Subtracting 5 from a number X can be represented as X - 5.

8) The difference of two numbers is 7, and the smaller number is y, then the greater number will be = ......

7y

7-y

Y-7

Y +7

The question states that the difference between two numbers is 7, and the smaller number is represented by y. To find the greater number, we need to add 7 to y. Therefore, the correct answer is y + 7.

Explanation

The question states that the difference between two numbers is 7, and the smaller number is represented by y. To find the greater number, we need to add 7 to y. Therefore, the correct answer is y + 7.

9) The perimeter of a rectangle is 20 cm. If its length is x cm , then its width = ..............

20 -x

20+ x

10 - x

10 + x

The width of a rectangle can be found by subtracting the length from the perimeter. In this case, the perimeter is given as 20 cm and the length is given as x cm. Therefore, the width would be 20 - x cm.

Explanation

The width of a rectangle can be found by subtracting the length from the perimeter. In this case, the perimeter is given as 20 cm and the length is given as x cm. Therefore, the width would be 20 - x cm.

10) If the sum of two numbers is 10 and one of them is X, then the other =.........

10 - x

X -10

X +10

10

The sum of two numbers is 10, and one of them is represented by X. To find the value of the other number, we subtract X from 10. This is because if we add X to the other number, it should equal 10. Therefore, the correct answer is 10 - X.

Explanation

The sum of two numbers is 10, and one of them is represented by X. To find the value of the other number, we subtract X from 10. This is because if we add X to the other number, it should equal 10. Therefore, the correct answer is 10 - X.
