Answer:
5*x=7
The answer is made by division
x=7/5
x=1.4
Step-by-step explanation:
The charge per unit of electricity is #415
The formula for E in terms of N is E = 375 + 40N
<h3>What is variation?</h3>
Variation is a mathematical term that establishes the relationship between quantities and variables in an equation.
Analysis:
E = K + CN
where K and C are constants
When E = 3655, N = 82 and when E = 2055, N = 42
3655 = K + 82C ---------------1
2055 = K + 42C----------------2
subtract equation 2 from 1
40C = 1600
C = 40
substitute C in equation 1
3655 = K + 82(40)
3655 = K + 3280
K = 3655 - 3280 = 375
charge per unit is N = 1
E = 375 + 40(1) = #415
Formula for E in terms of N is E = 375 + 40N
In conclusion, the charge per unit of electricity is 415 and the equation connecting E and N is E = 375 + 40N

Answer:
230.5
Step-by-step explanation:
Formulas: a = 1/2(bh), a = bh
Rectangle 1: a = 6 x 8
a = 48
Base of the triangle: 9 + 6
15
Triangle 1: a = 1/2(15 x 24)
a = 180
Triangle 2: a = 1/2(4(13 - 8))
a = 2.5
48 + 180 + 2.5
230.5
<u>The area of the figure is 230.5.</u>
