4 What is the number if 61 is 3 less than 8 times the number?
Mrrafil [7]

If 61 is less than 8 times the number then the number is 8.

Given 61 is 3 less than 8 times the number.

Let the number be 'x'.

The term "polynomial" in mathematics refers to a mathematical statement that consists of two or more algebraic terms that are added, subtracted, or multiplied (no division!). Constants and positive exponents are frequently used, together with at least one variable, in polynomial formulas.

we can write the equation as:

8x ₋₋ 3 = 61

arranging the like terms i.e constants.

8x = 61 ₊ 3

8x = 64

to find the value of x, divide 64 by 8.

x = 64 ÷ 8

x = 8

hence the number we get after solving the equation is 8.

Evaluate each expression if x = −2, y = −3, and z = 5.
Scrat [10]
Basically what you have to do is substitute the variables for the values

-4+-9+5= -8
-2-3= -5
2= 2 
6-4+1= 3
-9(-2+-4--3)= 27

a diver is swimming at -10 m. He then descends 3m and rises 6m. At what new level is the diver swimming?
iVinArrow [24]
So we start at -10. Because he descends 3 feet, We subtract 3, getting -13. He then rises 6 feet. -13 + 6 = -7. The diver is now at -7 feet.
