<u>Answer:</u>
-2/3
<u>Step-by-step explanation:</u>
We are to find the slope of a line which is perpendicular of a line with an equation 
.
We know that the slope of line which is perpendicular to another line is the negative reciprocal of that perpendicular line.
So writing the given equation of a line in the slope intercept form:
---> 
Here the slope of this line is 
so the slope of a line which is perpendicular to the given line will be 
.

Answer:
y=81/10
Step-by-step explanation:
2/3y - 2/5 =5
lcm=15
(10y-6)/15=5
10y-6=75
10y=75+6
10y=81
y=81/10
Well 32 x 405 is 12,960, but it ask for 2 numbers added to make 12,960 so the answer is 810 + 12,150 which is 2 products that add up to the answer 12,960.
The answer is 7 because 70 ÷ 10 = 7.
