Solve the equation: b/5 + 15 =45
is answer 150

Answers

Answer 1
Answer:

Answer: The answer is 150.

Step-by-step explanation:

First of all, we need to use inverse operations to solve this arithmetical equation.

First, multiply both sides by 5.

5(B/5 + 15) = 5(45).

B + 75 = 225.

Now we need to use the inverse operation of addition to get B by itself.

The inverse operation of addition is subtraction. And so we must subtract each side by 75.

B + 75 - 75 = 225 - 75.

B = 150.

So it looks like you are correct. 150 is the answer.

two sides of an equilateral triangle measure (y+10) and (y^2(-2)). if the perimeter of the triangle is 21 units what is the value of y?

Answers

Answer:

  y = -3

Step-by-step explanation:

Each side of an equilateral triangle will have a length that is 1/3 the perimeter. This triangle has sides of length 21/3 = 7, so ...

  y + 10 = 7

  y = 7 - 10

  y = -3

This is consistent with the other given side measure ...

  y^2 -2 = (-3)^2 -2 = 9 -2 = 7

The function A(r)=πr^2 may be used to find the area of a circle with radius r. Find the area of a circle whose radius is 11 centimeters. Please help me ASAP!!!!!!! :(

Answers

Just evaluate the function: A(r) = πr² by substituting 11 in for 'r'

so A(11) = π(11)²

or Area = 121π

Which phrases can be used to represent the inequality 12 minus 3 x greater-than-or-equal-to 9? Select two options.

Answers

Answer:

Twelve less three times a number is at least nine.

Twelve minus the product of three and a number is no smaller than nine.

Step-by-step explanation:

complete question is:

Twelve less than three times a number is greater than or equal to nine.

Twelve less than three times a number is at least nine.

Twelve less three times a number is at least nine.

Twelve minus the product of three and a number is no more than nine.

Twelve minus the product of three and a number is no smaller than nine.

ANSWER:

Twelve less three times a number is at least nine.

The phrase "twelve less three..." means that the "three times a number" is being subtracted from twelve. So, it has to be at least nine.

Twelve minus the product of three and a number is no smaller than nine.

Even the least number you suppose is 1 we'll get 9

e.g: 12-3(1)=9. Therefore, this statement also represent the inequality

Check attachment for the remaining part of the questions.

Answer:

The correct options are:

C. Twelve less three times a number is at least nine.

F. Twelve minus the product of three and a number is no smaller that nine.

Step-by-step explanation:

Given 12 - 3x ≥ 9,

we want to check which phrase from the options can be used to represent the inequality.

12 - 3x: This means the product of 3 and a number is subtracted from 12.

≥: This is the "Greater or equal to" symbol. It is used to show that the quantity on the left hand side of the symbol is at least, the exact quantity on the right. It means the quantity on the right hand side can be equal, or greater, but can never be smaller the quantity on the left hand side.

So, the statement means

When 3 is multiplied my a number, and then the result is subtracted from 12, what we have is at least 9.

The only statements that corresponds to this from the options are:

1. Twelve less three times a number is at least nine.

2. Twelve minus the product of three and a number is no smaller that nine.

Which expression represents the phrase " the difference of 18 and 12"?

Answers

Given:

The statement is "the difference of 18 and 12".

To find:

The expression for the given statement.

Solution:

We have,

Given statement = The difference of 18 and 12.

We use subtraction, to find the different between two numbers and subtraction is represented by negative sign. So, we need to subtract second number form the first number.

The difference of 18 and 12 = 18 - 12

Therefore, the required expression for the given statement is 18-12.
