the length of a rectangle is 5 less than 3 times the width. the perimeter is 150 centimeters. what is the length and width?
Answers
The width: y
x = 3y-5 (cm)
x + y = 150/2 = 75 (cm)
=> 3y-5+y = 75
=> 4y = 80
=> y = 20 (cm)
=> x = 3×20-5 = 55 (cm)

Answers
y = mx + b
where,
m is the slope
b is the y-intercept
So for the line:
y = 2/3x + 4
2/3 is the slope
4 is the y-intercept
The slope of y = 2/3x + 4 is 2/3

Firstly, it's easier if you convert both measurements to inches.
so you'd do 6 x 12 = 72 , 72 + 5 = 77 inches
and 4 x 12 = 48 , 48 + 3 = 51 inches.
Then you multiply the sides, so:
77 x 51 = 3927 inches
then you divide by 12 to get how many feet and inches it is
3927/12 = 327 feet and 4 inches

Answer:
a=95.0 in^2
Step-by-step explanation:
The area of a circle is:
a=r^2
First, we must find the radius
r=d/2
r=11/2
r=5.5
Substitute 5.5 in for r in the formula
a=5.5^2
a=30.25
Substitute 3.14 in for pi
a=3.14*30.25
a=94.985
Rounded to the nearest tenth:
a=95.0 in^2
Hope this helps! :)

We want to multiply the monomial by the monomial
.
Remember that to multiply monomials we need to use the laws of exponents; in this case, the law for multiplying powers with the same base. The rule says that, when you multiply powers of the same base, you just need to add the exponents: ,
. Also, is worth pointing out that the exponent of a variable with no exponent is 1:
.
Remember that we also need to multiply their coefficients , which are the numbers that multiply the variables; again, variables with no numbers have a coefficient of 1, so . Multiply coefficients is easy, you just need to multiply them as you usually do with everyday numbers.
Let's apply all of that to our multiplication:
We can conclude that 2x times x squared is 2x cubed.
times
is
.
Further explanation:
A monomial is an expression which contains one term and a monomial includes numbers and variables which are multiplied together. The constant term is multiplies with an another constsnt term and the variable is multiplies with an another variable term.
Law of exponent:
Product with same base: If we multiply the same bases with different exponents then the base remains the same and the exponents are added in the final product.
Calculation:
Now, we are given the two monomials as and
.
Multiplying both the monomials as follows:
Here, is a variable and
has power
in the first monomial and
has power
in the second monomial.
Using the mentioned law of exponents as the variable is similar in both the monomial and add the powers of both as follows:
Therefore, times
is
