Answer:
x = 11
Step-by-step explanation:
Given the expression;
5x+2y=67 ...1
x=3y−7 ....2
Substitute 2 into 1
5(3y-7)+2y = 67
15y - 35 + 2y = 67
17y = 67+35
17y = 102
y = 102/17
y =6
Recall that x = 3y - 7
x = 3(6) - 7
x = 18 - 7
x = 11
Hence the value of x is 11

Answer:
125 % increase
Step-by-step explanation:
assume a cube of side 10
then each side surface area = 100 * 6 = 600 units
now consider sides 15 (+50%)
each side = 225 .... 225 * 6 = 1350
(1350 - 600)/600 = 1.25 = 125 % increase
Hi there!
The equation of any line perpendicular to

is

Therefore, in this situation, the formula of the line would be

Given that the line passes through the point (6, 4) we get



Therefore, the equation of the line that is perpendicular to 3x + 9y = 7 and passes through (6, 4) is
