A discount of 20% multiplies the number by 1-.20=.8, so the price is going to be .8p.
Answer:
RT = 9
Step-by-step explanation:
x-2 + 4x-9 = x+5
5x-11 = x+5
subtract the x from the right side to 5x and the left side x cancels out
add 11 on the right side which cancels out and add to right side
4x = 16
divide 4x by 4 which cancels out and divide 16 by 4
x = 4
take the equation for RT = x+5
yk x = 4 so that makes 4+5 which is equal to 9
I hope this helps you
x^2+2x+8=0
x^2+2x+1+7=0
(x+1)^2= -7
(x+1)^2= i^2.7
x+1= i.square root of 7
x=-1+ i.square root of 7
A:b = 4:5
b:c=3:2
b was 5 then it was 3, so you have to find the common multiple which is 15.
you’d have to times the 4 (a) by 3 since that 5x3 is 15
you’d have to times the 2 (c) by 5 since 5x3 is 15 again.
therefore the answer would be
a:b:c
12:15:10
I hope this makes sense it was kinda hard to explain sorry :)
