The perimeter of the triangle is 13 inches. What is the length of the shortest side?
vlabodo [156]

Answer:

3 in

Step-by-step explanation:

Sum of all sides of ∆ = perimeter

Given that it has a perimeter of 13 in, and the following sides: (x - 5) in, x/2 in, and 6 in, therefore:

x - 5 + \frac{x}{2} + 6 = 13

Solve to find the value of x

\frac{2x - 10 + x + 12}{2} = 13

\frac{3x + 2}{2} = 13

Multiply both sides by 2

\frac{3x + 2}{2}*2 = 13*2

3x + 2 = 26

Subtract 2 from both sides

3x + 2 - 2 = 26 - 2

3x = 24

Divide both sides by 3

\frac{3x}{3} = \frac{24}{3}

x = 8

The shortest side = (x - 5) in

Plug in the value of x

= (8 - 5) in

= 3 in

Divide the year 2007 into 2 parts so that the second part is 4 times as large as the first part.
blondinia [14]
It doesn't matter which year it is. As long as it's not a leap year, it has 365 days.

If the second part has 4 slices in it and the first part is one slice, then you've
cut the whole thing up into 5 slices, and each slice is 365/5 = 73 days.

1). In the larger part, there are 4 slices x 73 days = 292 days.

2). In the shorter part, there is one slice of 73 days.

3). If the shorter part starts on January, it ends on the 73rd day
of the year.  Pull out a calendar and count 'em.
The 73rd day looks like it's March 14.

A simple is an argument made of three statements​
Angelina_Jolie [31]

Answer:

An argument can be broken down into three major components: premises, inferences, and a conclusion. Premises are statements of (assumed) fact which are supposed to set forth the reasons and/or evidence for believing a claim. The claim, in turn, is the conclusion: what you finish with at the end of an argument.
