7n - 4 = 31

Mathematics
1 answer:

7n - 4 = 31

move -4 to the other side

sign changes from -4 to +4

7n-4+4= 31+4

7n= 31+4

7n= 35

divide both sides by 7 to get n by itself

7n/7= 35/7

cross out 7 and 7 , divide by 7 and then becomes 1*1*n= n

n= 35/7

answer:

n= 5

Which equation represents the line passing through the points (3, 2) and (–9, 6)?
prisoha [69]
(3,2),(-9,6)
slope = (6 - 2) / (-9 - 3) = -4/12 = -1/3

y = mx + b
slope(m) = -1/3
use either of ur points...(3,2)....x = 3 and y = 2
now we sub into the formula and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b
so ur equation is : y = -1/3x + 3 <==

Answer:

  5 ft

Step-by-step explanation:

The area of a trapezoid is given by the formula ...

  A = 1/2(b1 +b2)h

The height is found by solving this equation for h:

  2A/(b1 +b2) = h

  h = 2(25.5)/(3.2 +7) = 51/10.2 = 5 . . . . fill in the given values

The height of the trapezoid is 5 feet.
