The answer is: " - (4/3) " .

Explanation:
____________________________________
The original equation given has a slope of (3/4).
Note: We know this since the equation for the slope of the line is written in "slope-intercept form" ; also known as: "point-slope form"; that is:
" y = mx + b " ; in which "m" (the coefficient of "x") is the slope.
____________________________________________________
The slope of a line PERPENDICULAR to an equation, when written in "slope-intercept form", is the "negative reciprocal" of the slope of the original line.
Hence, the negative reciprocal of "(3/4)" is: "-(4/3)" .

Answer:
up 2, right 3
Step-by-step explanation:
up 2, to the right 3.
Let x represent the amount of dimes
Let y represent the amount of nickles
So since he has 20 coins, x + y = 20
and if we want to find the total money of dimes, we have to multiply x with 10
So 10x + 5y = 165 (in cents)
2x + y = 33
-x - y = -20
x = 13
so x = 13 and y = 7
Hope this helps :)
Answer in fraction form: 5/8
Answer in decimal form: 0.625
==============================================
Explanation:
There are 5 sides that aren't labeled "1" out of 6 total. So the probability of not rolling a "1" on the six-sided die is 5/6
Similarly, there are 3 sides that aren't labeled "1" out of 4 sides on the four-sided die. The probability of not rolling a "1" for this die is 3/4
Multiply the fractions
(5/6)*(3/4) = (5*3)/(6*4) = 15/24 = 5/8
The answer in fraction form is 5/8 which converts to 0.625 (use long division or a calculator)
Note: the multiplication of probabilities works because the two events (of rolling each die) are independent
180 - 130 = 50°
opposite sides add up to 180
