Hello,
Here in Europe, we know a nice sign"+" which means addition !!!!!!!
|5|=5
|-6|=6
|5|+|-6|=5+6=11
1.= 1
2.= -15
3.= -18
4.= -1
5. = -11
6. = 22
Answer:
50$
Step-by-step explanation:
$1.25x40= 50 so she would have to pay 50$
So since they are similar
AC/BC=CD/CE
so
(66-x)/30=(x+4)/5
times both sides by 5
(66-x)/6=x+4
times both sides by 6
66-x=6(x+4)
distribute
66-x=6x+24
add x to both sides
66=7x+24
minus 24 from both sides
42=7x
divide both sides by 7
6=x
x=6 units
Answer:
it would be B.
Step-by-step explanation:
if you do 4x+20=3x
then you solve x by simplifying both sides of the equation and isolate the variable.
