Answer:

8y+57+2y+83 =180

 10y+140=180

 10y =180-140

 y =4

CPH=2y+83

 =8+83

 =91

The number of children at the library was 3 times the uninvited of adults. The total number of people at the library was 48. How

Citrus2011 [14]

Answer:

Step-by-step explanation:

In equation form,

children + adults = 48 people at the library.

If the number of children is 3 times the number of adults, then in equation form:

children = adults*3

Let's call children c and adults a. Subbing the second equation into the first gives us an equation with only one unknown instead of 2.

c + a = 48 after making the substitution is

3a + a = 48 and

4a = 48 so

a = 12

There were 12 adults. If the total number of people was 48, then

48 - 12 = number of children so

c = 36

When solving a literal equation, what is the trick for isolating a variable that appears more than once?

Paha777 [63]

Literal equations, simply put, are equations containing two or more variables. Your goal is to solve for just one variable with respect to others. If you know how to solve regular equations, then I guarantee you that solving literal equations will be a breeze.

The "heart" of literal equation is to isolate or keep by itself a certain variable on one side of the equation (either left or right) and the rest on the opposite side.

What is the circumference of a circle with a radius of 25 feet?

Luda [366]

Answer: 157 ft

Step-by-step explanation: To find the circumference of a circle, start with the formula for the circumference of a circle which is shown below.

Circumference = 2πr

Notice that the circle has a radius of 25 feet. So we can plug in 25 feet for r in the formula. So we have (2)(π)(25 ft) which is equal to 50π ft.

Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.

So we have (50)(3.14) which is equal to 157.

So the circumference of the circle is approximately equal to 157 ft.
