B) 13 more than half of the quotient of 6 and 6 minus 2
C) Half of 13 multiplied by the quotient of 6 and 2 plus 3
D) 13 plus half of 6 divided by 2, then subtract 6

Answers

Answer: It's A.

Step-by-step explanation:

I did the test and I got it right

The expression should be described option A. A) 13 more than half of 6 more than the quotient of 6 and 2

Description of an expression:

Since the expression is 13 + fraction 1/2 x (6 ÷ 2 + 6)

So we can explained that 13 should be more than the half of 6 i.e. more than the quotient of 6 and 2.

Therefore, the option A is correct.

And, the rest of the options are wrong.

Step-by-step explanation:

Find the lowest number divisible by both 6, 5, and 2.

To start, let's list off the numbers divisible by six, and see if we can check any of them off for 5. Since both 2 and 6 are even numbers, we know that if a number is divisible by 6, it's divisible by 2.

6 12 18 24 30 36 42 48 54 60

All of these numbers are divisible by two. Let's find the lowest one that is divisible by 5. We know this by either the umber ending in 5 or 0.

30 is the lowest number that is divisible by 2, 5, or 6.

The size of the angle 'x' is 117°

The external angle of a triangle:

An external angle of a triangle is an angle formed by extending one side of the triangle and intersecting with the extension of another side.

In a triangle, the measure of an external angle is equal to the sum of the measures of the two opposite interior angles.

Here we have a triangle

Let the ABC be the triangle as given in the picture

=> ∠A = 38°

From the baseline BC

=> Measure of B = 180° - 101° = 79°

As we know

In a triangle, the measure of an external angle is equal to the sum of the two opposite interior angles

=> x = ∠A + ∠C

=> x = 38° + 79°

=> x = 117°

Therefore,

The size of the angle 'x' is 117°
