-3 times (x+8)=-21
-3(x+8)=-21
distributive property=a(b+c)=ab+ac
-3(x+8)=-3x+(-3)(8)=-3x-24
-3x-24=-21
add 3x to both sides
-24=-21+3x
add 21 to both sides
-3=3x
divide both sids by 3
-1=x
x=-1
Answer:
Step-by-step explanation:
Answer:30+12=42
Step-by-step explanation:
P/M=6/7(2) P/M=12/14
P/M+16=2/5(6) P/M=12/30
Başlangıçtaki M+16=30 M=30
P=12
P+M=42
The slope is 25
y=mx+b with m representing slope
y=25x+50
