Write an expression for the perimeter of the triangle shown below:

emmainna [20.7K]

Since the perimeter is the length of all 3 sides added up, we do:

2.3x + 14 + -0.2x + 15 + 2x = 4.1x + 29, which is the same as answer a. So, the answer is a, or 4.1x + 29.

7) Number of Calendars Cost 6 $114 8 $144 10 $160 15 $180 20 $300 A gift store is ordering calendars to resell. The table shows

laila [671]

Answer:

The best value is $\$ 180$ for $15$ calendars.

Step-by-step explanation:

Lets find out the unit cost of each calendars with different prices given here.

The price of $6$ calendars is $\$ 114$ .

Unit cost of these calendars $= \frac{114}{6} = \$ 19$

The price of $8$ calendars is $\$ 144$ .

Unit cost of these calendars $= \frac{144}{8} = \$ 18$ .

The price of $10$ calendars is $\$ 160$ .

Unit cost of these calendars $= \frac{160}{10} = \$ 16$ .

The price of $15$ calendars is $\$ 180$ .

Unit cost of these calendars $= \frac{180}{15} = \$ 12$ .

The price of $20$ calendars is $\$300$ .

Unit cost of these calendars $= \frac{300}{20} = \$ 15$ .

So the best value from customer point of view is the lowest unit cost.

And the lowest cost is being offered for $15$ calendars $\ @\ 12\$$ per calendar.

Answer the following questions regarding the graphed inequality.

arsen [322]

Answer:

m = 0.5, b = 2, greater than symbol >

Step-by-step explanation:

Slope:

We can find the slope value by choosing two points on our line (the two green dots are already chosen for us) and dividing the vertical distance between the points (this is called the rise) by the horizontal distance between the points (this is called the run)

Rise ÷ Run

1 ÷ 2 = 0.5

Y-Intercept:

The y-intercept is where the line cuts through the vertical y-axis. We can see that this is at y = 2

Inequality:

The area above the line is shaded in. This is to show that all values greater than the line are applicable, so we will use the greater than symbol, >
