Step-by-step explanation:
7x + 8 + 15 - 7x
Solving like terms
23
Option C is the correct answer
N=-2
Add 42 to both sides to get -6n=12
Divide both sides by -6
Answer:
first would be 5-6 and second would be 8-10
Step-by-step explanation:
If R is between Q and S then QR+RS=QS
given
QR=x+4
RS=3x-1
and QS=27
x+4+3x-1=27
combine like terms
4x+3=27
minus 3 both sides
4x=24
divide both sides by 4
x=6
sub back
QR=x+4
QR=6+4
QR=10
RS=3x-1
RS=3(6)-1
RS=18-1
RS=17
x=6
QR=10
RS=17
Prime for 2 digit odd number: 13 , 11 , 17, etc
Odd number that is composite: 39, 25, 15, etc
Hope this helps
