Answer:
Step-by-step explanation:
The square root is possible only if y≤0
if y>0 the expression lose meaning, in fact (-)(+)(+) = (-) and a square root of a negative number doesn’t exist. x^2 is a square so it is ever positive if x is not 0
if y≤0 can be rewritten as:
3(-27x^2y^7)^1/2
or if we want simplify the expression:
^1/2
we have to put the symbol of absolute value between x and y because a x^2 and y^6 are numbers that are ever positive, while x and y^3 can be also negative. Thanks to the simbol of absolute value we can “force” them to be positive
The answer is 45 total.
So Tommy is 22 years old while his Father is 45.
45 years of age total, tommy is 23 years younger so 45 - 23 = 22 so tommy is 22 while his father is 45.
Answer:
9/14
Step-by-step explanation:
3/7 ÷ 2/3 <----- write down the problem
= 3/7 × 3/2 <----- multiply by its reciprocal
= 9/14 <----- simplify
The amount of shirts and pants the clothier makes is an illustration of a linear equation
The equation that represents the number of shirts, and the number of pants is 4s + 6p = 40
<h3>How to determine the equation</h3>
The rates are given as:
Shirts = 4 hours
Pants = 6 hours
In time t, the shirts and pants made is represented with:
t = 4s + 6p
Given that the time is 40 hours, the equation becomes
4s + 6p = 40
Hence, the equation that represents the number of shirts, and the number of pants is 4s + 6p = 40
