Answer:
.25x+1.75=15 and x=53
Step-by-step explanation:
first subtract 1.75 from both sides
then divide by .25 on both sides
and you will get x=53
Answer:
Step-by-step explanation:
Given:
Fixed salary earned by Jeanette per week = 
Additional amount earned by her for each sign she sells = 
To find: linear equation which represents her weekly pay based on the number of signs she sells.
Solution:
Let number of signs sold by Jeanette be x
So, her weekly pay = fixed pay + Additional amount earned by her for each sign she sells
The formula of the area of a trapezoid is equal to:
Area = (a+b) / 2 * h
Substituting the values.
9 = (2.4 + 3.6) / 2 * h
9 = 6 / 2 h
9 = 3h
h = 3
So the height of the trapezoid is equal to 3m.
14-2x=6+12x
14=6+10x
8=10x
0.8=x
Answer:
L = 15, W = 8
Step-by-step explanation:
Perimeter = 2(L + W)
P = 40
L = 2W - 1
40 = 2((2W-1) + W)
40 = 4W - 2 + 2W
40 = 6W - 2
42 = 6W
W = 8
Since L = 2W - 1
L = 2(8) - 1
L = 15
