First lets find -8.2 x 10 = -82 know we find 82^5 which is 82*82*82*82*82
-82*-82=6724 and then 6724*-82= -551368 and then -551368*-82 =45212176 and then 45212176*-82= -3707398432 and finally -3707398432 is our answer i checked the calc to after i did the hard math that took me forever i had some help from the calc and i got this hopefully this helps
Answer:X=5 or 7
Step-by-step explanation:
Answer: x < 2
Step-by-step explanation:
Let's solve your inequality step-by-step.
6.2x+1<21−3.8x
Step 1: Simplify both sides of the inequality.
6.2x+1<−3.8x+21
Step 2: Add 3.8x to both sides.
6.2x+1+3.8x<−3.8x+21+3.8x
10x+1<21
Step 3: Subtract 1 from both sides.
10x+1−1<21−1
10x<20
Step 4: Divide both sides by 10.
10x/10 <20x/10
x < 2
Answer:
Step-by-step explanation:
20 total
6 have average of 5 years
6 x 5 = 30
20-6 = 14
14 have average of 8 years
14 x 8 = 112
112 + 30 = 142
142 / 20 = 7.1 years
