Answer:
1) x=1/2-y/2-3z
2)x= 16/3- 2y/3- 5z/3
3)x= 11/7- 3y/7+ 4z/7
Step-by-step explanation:
isolate the variable, to do that divide each side by the factors that don't contain the variable
You end with 210.85. add 75.50 and 55.25 together you get 130.75. 130.75-25.15-18.65 = 86.95. 210.85-86.95= 123.90 work backwards.
Answer:
It would take him 8 hours
Since every 50 miles takes 1 hour
Well 7 goes into 15 7 times and theres one left over so there would be one left out
Answer:
longer side = √507 cm, shorter side = 13 cm
Step-by-step explanation:
sin60 = opposite side/26cm
opposite side = √507 cm
cos60 = adjacent side/ 26cm
adjacent side = 13 cm
longer side = √507 cm, shorter side = 13 cm
