Answer:

27.5 (is greater than) -2.5

Step-by-step explanation:

Distribute 5/3 to 6x and 9, (5/3•6x)+(5/3•9)=10x+15.

Set 10x+15 equal to 2x-5

10x+15=2x-5

(get rid of the smaller slope)

-2x -2x

8x+15=-5

+15 +15

8x=10

(divide by 8 to get the value of x)

8x divided by 8=x

10 divided by 8=1.25

x=1.25

Plug the known value of x back into the equations.

10(1.25)+15=27.5

2(1.25)-5=-2.5

27.5 (less than or equal to) -2.5 is incorrect. It would be

27.5 (is greater than) -2.5

Please help i need to write out my work to so please tell me how to show it

Anarel [89]

For the first one write 9 divided by 2 gives your your radius an it’s 3.5. the formula is 2 x 3.14 x radius and that gives you 21.98.

the 2nd one is 2 x 3.14 x 9 = 56.52

the 3rd is 2 x 3.14 x 5= 31.4

formula is always 2 x 3.14 (or pie) x radius

to get your radius from your diameter you do your diameter divided by 2

The pentagon below has an area of 8.3 square centimeters and a side of 2.2. What is the approximate length of the apothem? A.0.4

nalin [4]

Answer:

C. 1.5 cm

Step-by-step explanation:

A pentagon is a polygon with 5 sides.

The formula for the area of a regular polygon is

$A=\frac{1}{2}ap$

where a is the apothem and p is the perimeter. The perimeter is found by multiplying the number of sides of the figure by the length of 1 of those sides:

5(2.2) = 11

Now we have everything we need to solve for the length of the apothem.

$8.3=\frac{1}{2}a(11)$
