Answer:

the value of a is 20

Step-by-step explanation:

8a-15-6a = 85-3a

or, 2a-15 = 85-3a

or, 2a+3a = 85+15

or, 5a = 100

or, a = 100/5

or, a = 20

therefore, a = 20

I hope it helped u. plz mark brainliest!

The diameter of the circlular garden is 16 feet what is the approximate area of the garden? Please hurry

SIZIF [17.4K]

The formula for an area of a circle is pi•r^2.
The diameter is 16, so the radius (half of the diameter) is 8. plug that into the formula and you get 64pi, or roughly 200.96

A triangle has side lengths measuring 2x + 2 ft, x + 3 ft, and n ft. Which expression represents the possible values of n, in fe

cluponka [151]

Answer:

$x-1$

Step-by-step explanation:

If a, b and c are the lengths of the triangle's sides, then

$a+b>c,\\ \\a+c>b,\\ \\b+c>a.$

Since

$a=2x+2,\\ \\b=x+3,\\ \\z=n,$

then

$2x+2+x+3>n\Rightarrow nx+3\Rightarrow n>1-x,\\ \\x+3+n>2x+2\Rightarrow n>x-1.$

Thus,

$x-1$

PLEASE HELP!!!!<br><br> Use the table below to match the slopes to the lines.

skelet666 [1.2K]

Answer: Check out the filled out chart below.

Row 1: 1/4, 1/4, -4

Row 2: -2, -2, 1/2

Row 3: 3, 3, -1/3

=========================================

Explanation:

Parallel lines have equal slopes. So if the original line has slope 1/4, then any parallel line will also have slope 1/4. The only thing different is the y intercept.

Perpendicular slopes multiply to -1 assuming neither line is vertical. For row 1, the perpendicular slope is -4 which multiplies with the original slope 1/4 to get -1.

Put another way, the perpendicular slope is the negative reciprocal of the original slope. For row 2, the perpendicular slope is 1/2 because we flip the fraction and the sign for the original slope -2 = -2/1
