Two consecutive numbers whose sum is 115​

Mathematics
1 answer:
kykrilka [37]2 years ago
4 0

Answer:

The two numbers would be 57 and 58.

Step-by-step explanation:

You can solve this problem using algebra.  Use x to represent the smaller number and x + 1 to represent the greater number.  You use x + 1 to represent the larger number because it is 1 more than the smaller number.

x + (x + 1) = 115

2x + 1 = 115

2x = 114

x = 57

Therefore, the numbers are 57 and 58.  You can plug 57 into x + 1 to find the larger number.

Determine which set of side measurements could be used to form a right triangle.
musickatia [10]

The set of side measurements that could be used to form a right triangle is 3, 4 and 5 option (D) is correct.

What is a right-angle triangle?

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

It is given that:

The side length of the triangle is shown in the option:

As we know,

Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.

Using Pythagoras' theorem:

From option(D):

3, 4 and 5

(3)² + (4)² = 5²

9 + 16 = 25 (True)

Thus, the set of side measurements that could be used to form a right triangle is 3, 4 and 5 option (D) is correct.

Kenya is solving the equation 5 3/4 - 1/6x = 4 1/2. She gets to 1 1/4 = 1/6x. Is this a valid way to solve the equation? answer
Alona [7]

Answer:

15/2

Step-by-step explanation:

5 3/4 - 1/6x = 4 1/2

move the variable to it's own side.

5 3/4 - 4 1/2 = 1/6x

change the subtracting side to have common denominators

5 3/4 - 4 2/4 = 1/6x

1 1/4 = 1/6 x

divide both sides by 1/6, same thing as multiplying both sides by 6 (reciprocal)

30/4 = x

reduce: 15/2 = x
