Answer:
x = 11.0
Step-by-step explanation:
b = √c2 - a2
= √132 - 6.88895043503172
= √121.54236190368
= 11.02463
9/10n + 6 = 51
9/10n = 51 - 6
9/10n = 45
n = 45 * 10/9
n = 450/9
n = 50
You can round 790 to 800, and 9 to 10. So then it become 800/10, or 80. Your answer would be around 80. Hope I helped!
389,420 because one hundred thousand is 100,000 so you just round the last number .
