The value of n that will make the expression equal is 13
<h3>Equations and expression</h3>
Equations are expressions separated by equal sign
Given the equation
11n = 143
Divide both sides by 11 to have;
11n/11 = 143/11
n = 13
Hence the value of n that will make the expression equal is 13

Answer:
m+n=23
Step-by-step explanation:
the modes m and n have to be data points more than 1 time, but equal
if there are 7 data points, then there are 4 unknown left/2 2 each
(2m-3+m+12+3n+2+m+m+n+n)/7=18
(3m+9+3n+2+m+m+n+n)/7=18
(5m+5n+11)/7=18
(5/7)*m+(5/7)*n+11/7=126/7
(5/7)*m+(5/7)*n=115/7
5m+5n=115
m+n=115/5
m+n=23
Answer:
3c + 2x + 11
Step-by-step explanation:
Answer:
Equation for x: 3x - 6 = 
x = 9
CD = 17
GH = 21
Step-by-step explanation:
The midsegment formula for a trapezoid is
GH = 
3x - 6 =
6x - 12 = 2x + 24
4x = 36
x = 9
CD = 2x - 1 = 2(9) - 1 = 18 - 1 = 17
GH = 3x - 6 = 3(9) - 6 = 3 = 27 - 6 = 21
