Answer:
121
Step-by-step explanation:
Number of sides = n = 7
Sum of all the interior angles = (n -2)*180 = (7-2) *180
= 5 *180
= 900
x + 125 + 119 +117 +145 + 133 + 140 = 900
x + 779 = 900
x = 900 - 779
x = 121
Answer:
x = 121°
Step-by-step explanation:
The formula to find the sum of interior angles of a polygon is:
180 ( n - 2 )
Here,
n ⇒ number of sides ⇒ 7
First, let us find the sum of the interior angles of the polygon.
180 ( n - 2 )
180 × ( 7 - 2 )
180 × 5
900°.
Accordingly, let us make an expression to find the value of x.
145 + 133 + 140 + 125 + 119 + 117 + x = 900
Let us solve for x now.
779 + x = 900
Subtract 779 from both sides.
x = 900 - 779
x = 121

Circumference (c) = 19.8 in
Radius (r) = ?
We know
2πr = c
2 * 3.14 * r = 19.8
6.28 r = 19.8
r = 19.8 / 6.28
r = 3.2 in

Answer:
y -10 = 1/8(x +8)
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
You have m = 1/8, and (h, k) = (-8, 10).
Putting those numbers in the form gives ...
y -10 = 1/8(x -(-8))
You can simplify the double minus sign so you have ...
y -10 = 1/8(x +8)

a belt and a wallet cost $42.7 belts and 4 wallets cost $213.If the cost of a belt is $x and the cost of a wallet is $y, form two linear equations in x and y and solve them to find the cost of each item
Answers
hope it helps yah T-T
cost of a wallet = y
Then, system of equations would be:
x + y = 42
7x + 4y = 213
Multiply 1st equation by 4,
4x + 4y = 168
Substitute it from 2nd equation,
3x = 45
x = 15
Now, substitute it in 1st equation,
15 + y = 42
y = 42 - 15 = 27
In short, Belt costs $15 and wallet costs $27
find the slope of the line that passes through (6, 3) and (10, 6)
Answers
Step-by-step explanation:
3/4
insert 1st point into y=mx+b
3=m(6)+b
insert 2nd point into y=mx+b
6=m(10)+b
-----------------------------------
use system of equations to solve for m and b
b=3-6m
b=6-10m
3-6m=6-10m
4m=3
m=3/4
insert back into the equation
3=(3/4)6+b
3=9/2+b
3-9/2=b
-3/2=b
insert back into y=mx+b
m=slope
b=y-intercept
y=(3/4)x-3/2
slope=3/4
