Equation Solving | MCQs

Explanation

The sum of the interior angles of a triangle is 180 degrees.

x-35 + x-25 + 1/2x - 10 = 180

2.5x -70 = 180

2.5x = 250

x=100

Explanation

when 32 divided by 4 and added 40 to gives 48.40 to gives 48.

Explanation

To find the average (arithmetic mean) of a and b, we need to first solve for a and b.

Given equation: 10a + 10b = 35

Divide both sides by 10: a + b = 3.5

Since we want to find the average of a and b, we can use the fact that the average of two numbers is equal to their sum divided by 2.

So, (a + b)/2 = 3.5/2

= 1.75

Therefore, the average (arithmetic mean) of a and b is 1.75.

Explanation

Given that x added to itself 13 times gives 112:

x + 13x = 112

14x = 112

x = 112 / 14

x = 8

Explanation

Answer is 43628,

Explanation:

• Last digit of 2nd number,
• first digit of 1st number,
• middle digit of 2nd number,
• 2nd digit of 1st number,
• first digit of 2nd number
  

Explanation

2m = √(2) × √(72)

2m = 1.5 × √(72)

2m = (1.5)(8.5)

2m = 12.

m = 12/2

m= 6
