Find the degree of each algebraic expression

morpeh [17]

Step-by-step explanation:

The degree of an algebraic expression is the largest exponent of the variable present. In expressions with multiple variables, the exponents of each variables are added.

First Expression;

pq: Degree = 1 + 1 = 2

p²q: Degree = 2 + 1 = 3

p²q²: Degree = 2 + 2 = 4

The degree of this expression is 4

Second Expression;

2y²z: Degree = 2 + 1 = 3

10yz: Degree = 1 + 1 = 2

The degree of this expression is 3

12 less than the quotient of a number and seven is -2 find the number

kiruha [24]

A quotient is the result of a division.
Let the unknown number be x.

We translate the problem into an equation, piece by piece.

"quotient of a number and seven" ----> x/7

"12 less than the quotient of a number and seven" ----> x/7 - 12

The word "is" means "="
x/7 - 12 =

All the above is -2, so it equals -2.

x/7 - 12 = -2

$\dfrac{x}{7} - 12 = -2$

First, add 12 to both sides and simplify.

 $\dfrac{x}{7} - 12 + 12 = -2 + 12$


 $\dfrac{x}{7} = 10$ 

Next, multiply both sides by 7.

$\dfrac{x}{7} \times 7 = 10 \times 7$

$x = 70$

Answer: The number is 70.
