Answer:3
Step-by-step explanation: So if we start by breaking it down -5+ (5+3) we do the parentheses first (5+3) which equals 8. Then we are left with (-5)+8 and it would equal 3.
Anywhere within three standard deviations would be usual. So the fourth one, 59.6 mpg or 45.2 mpg would be unusual.
Answer:
m<PKN = 270 - m<JKP
Step-by-step explanation:
m<JKM + mMKL + m<LKN = 90 + 90 + 90 = 270
m<PKN + m<JKP = 270
4(a + 10) = 80
4a + 40 = 80
4a + 40 - 40 = 80 - 40
4a = 40
4a/4 = 40/4
a = 10
