12 less than 7 times a number, how do I put this in numbers and symbols and letters

Answers

Answer:

7x - 12

Step-by-step explanation:

'12 less' means thats u have to subtract 12 from the next number

'7 times a number' means 7 multiplied by a variable like x, y, or z

you put those two together and get 7x - 12

Answer: 7x-12

Step-by-step explanation:

“12 less than” would simply imply “subtract 12 from” the sum of 7 times a number. Let “x” represent the unknown number and multiply it by 7.

2. Classify the angle as acute, obtuse, right or straight.
O acute
O obtuse
Oright
straight

HELP ASAP

Answers

Answer:

Please include the details of the angle

Step-by-step explanation:

When the angle is 93 degrees, the the angle is a obtuse angle. option B is correct.

Given that the measure of angle A is 93 degrees, we can classify the angle as follows:

Angle A = 93 degrees

We know that if angle is less than 90 degrees, it is acute.

if angle is greater than 90 degrees, it is obtuse.

if angle is equal to 90 degrees, it is right angle.

Since the angle measures greater than 90 degrees, it falls within the range of an obtuse angle.

Therefore, the correct classification for angle A is obtuse.
