Answer:

176 books

Step-by-step explanation:

Let's call the number of fiction books 'F', and the number of non-fiction books 'N'. Then, we can write the following system of equations:

eq1:

F = 3N

eq2:

2*(F - 122) = (N - 24)

2F - 244 = N - 24

2F = N + 220

Using the 'F' value from the first equation, we have:

6N = N + 220

5N = 220

N = 44\ books

F = 3N = 132\ books

The total number of books is:

F + N = 132 + 44 = 176\ books

Step-by-step explanation:

find all factors of 8 other than 1, you should have 3

divide the whole equation by the factor then multiply by the factor

2(8x-12)/2 = 2(4x-6)

4(2x-3)

Erin’s car uses 6 gallons of gas for every 138 miles she drives.which equation could be used to find how many gallons,g, Erin ne
gladu [14]

The equation that could be used to find how many gallons Erin would need to drive 92 miles is 92 = 23g (option c)

<h3>How many gallons is needed to drive 92 miles?</h3>

The first step is to determine the gallons needed to drive 1 mile. To do this, divide the  6 gallons by 138 miles. Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.

Gallons needed for 1 mile = 6/138

In order to determine the gallons needed for 92 miles, multiply the ratio gotten in the previous step by 92

(6/138) x 92 = 4 gallons

The option that gives 4 gallons is : 92 = 23g

g = 92 / 32 = 4

Please help exponents and scientific notation
Anna007 [38]
Alright! When you have a constant to a power times another constant to a power (ex. [x^3 times x^3] ) you simply add the powers and keep the base [x^6]. When you have a power to a power (ex. [(12^3)^3] ) you multiply the powers and keep the base [12^9]. When you have a constant to a power divided by a constant to a power (ex. [ x^2 divided by x^5] ) you subtract the powers and keep the base. It's hard to see the questions, so I'll leave this here for you to use as a guide.
