igh school, it contained Algebra I, Geometry, and Algebra II textbooks. A label on the box reads: “Contents: 23 books, Weight: 93 lbs.” An Algebra I book weighs 4 pounds, a Geometry book weighs 3 pounds, and an Algebra II book weighs 5 pounds. The number of Geometry books and Algebra II books combined is one less than the number of Algebra I books.
Formulate a system of equations to represent the problem situation.
Solve the system of equations to determine the number of Algebra I textbooks, the number of Geometry textbooks, and the number of Algebra II textbooks that are in the box.

Answer:

Step-by-step explanation:

Let us represent the number of books as:

Algebra 1 = A1

Algebra 2 = A2

Geometry = G

A1 + A2 + G = 23........Equation 1

An Algebra I book weighs 4 pounds, a Geometry book weighs 3 pounds, and an Algebra II book weighs 5 pounds.

4A1 + 5A2 + 3G = 93

Chi chi can hit The golf ball 72 yards. Rory Can hit a golf ball 24 yards. How many times further can Chi chi hit a golf ball th
ivanzaharov [21]

Answer:

Chi chi canhit a golf ball three times further than Rory.

Step-by-step explanation:

To compare the distance between the two golfers, we can set up a ratio:

\frac{Chi chi Distance}{Rory Distance} = \frac{72}{24} =\frac{3}{1}

Since the distance that Chi chi can hit the ball is 3:1 the distance that Rory can hit the ball, than Chi chi can hit the golf ball three times further.  When reducing a ratio or fraction to lowest terms, you need to divide the numerator and the denominator by the same factor.  Since 72 can be evenly divided by 24, we can divide both the numerator and the denominator by 24 to get 3:1.
