Answer:

15=x 5x=75

Step-by-step explanation:

90/6=15

6 is how many x's there are in total meaning that 1 x = 15

15*5=75 so one angle is 15 while the other is 75

75 + 15= 90

90+90=180 getting you the 180 degrees

Subtract (r - 3q + 5p) - (-4r - 3q - 8p)

Alex787 [66]

Answer: ok so Let's simplify step-by-step.

r−3q+5p−(−4r−3q−8p)

Distribute the Negative Sign:

=r−3q+5p+−1(−4r−3q−8p)

=r+−3q+5p+−1(−4r)+−1(−3q)+−1(−8p)

=r+−3q+5p+4r+3q+8p

Combine Like Terms:

=r+−3q+5p+4r+3q+8p

=(5p+8p)+(−3q+3q)+(r+4r)

=13p+5r

The sum of two numbers is 24 and their quotient is 5 <br> what are the two numbers

ELEN [110]

The numbers are "x" and "y";
Therefore, we can suggest this system of equations:
x+y=24 ⇒x=24-y
x/y=5

solve this problem by substitution method.
(24-y)/y=5
24-y=5y
-y-5y=-24
-6y=-24
y=-24/-6=4

x=24-y
x=24-4
x=20

Answer: the numer are: 20 and 4
