Answer:
x = 4
Step-by-step explanation:
6x - 9 = 15
6x - 9 + 9 = 15 + 9
6x = 24
6x / 6 = 24 / 6
x = 4
The answer should be X= 3.60m
Answer:
5y - 6x = 8 or y = 6x/5 + 8/5
Step-by-step explanation:
let M1= gradient of line AB and M2= gradient of the second line
When two lines are perpendicular, the product of their gradients is -1
i.e, M1M2= -1
M2= -1/M1
A(2,9) and B(8,4)
gradient= (y2-y1)/(x2-x1)
M1= (4-9)/(8-2)
= -5/6
M2= -1÷ -5/6
-1 × -6/5= 6/5
Equation of the line passing through C(-3,-2)
[y-(-2)]/[x-(-3)= 6/5
(y+2)/(x+3)= 6/5
5(y+2)= 6(x+3)
5y+10=6x+18
5y= 6x + 8
y= 6x/5 + 8/5
Answer: 360
Step-by-step explanation:
The area of the bottom square is 100.
The area of each of the four triangular faces is 65.
Adding these together, we get 65(4) + 100 = 360.
Answer:
x = 5
Step-by-step explanation:
Given
6 = 3x - 9 ( add 9 to both sides )
15 = 3x ( divide both sides by 3 )
5 = x
