Answer:
42
Step-by-step explanation:
First condense all the numbers with exponents:
3² x 5³x 8 divided by 3 x 5³ x 8
27 x 125 x 8 divided by 3 x 27 x 8
Then multiply 27 , 125 ,and 8
27 x 125 x 8 =27000
Then multiply 3, 27 ,and 8
3 x 27 x 8 = 648
Then divide 27000 by 648
27000 / 648 = 41.6666666667
Which rounds to about: 42
To find the total mass you must first convert 40 oz into lbs. There is 16oz per pound. so 40/16 = 2.5 . 600 lbs +2.5 lbs = 602.5 lbs skull
Answer:
x=7 and y=4
Step-by-step explanation:
I will use the elimination method:
Since the co-efficient of both y's are the same number but different signs we add the 2 equations to eliminate the y:
3x + y =25
+ + +
2x - y = 10
Simplify:
5x=35
Divide both sides by 5:
5x÷5=35÷5
Simplify:
x=7
Substitute this into either equation 1 or 2 ( I chose 1):
3(7) + y = 25
21 + y = 25
Subtract 21 from both sides and simplify to get y:
21+y-21=25-21
y=4
Therefore x=7 and y=4
