Answer:
Step-by-step explanation:
145+15x>490. subtract 145 from both sides
15x>345, divide both sides by 15
x>23

Answer:
23 2/5
Step-by-step explanation:
convert mixed numbers to improper fractions: 1 3/10=13/10
13/10*18
convert element to fraction: 18=18/1
=18/1*13/10
cross cancel common factor:2
=13/5*9/1
multiply fractions
=13*9/5*1
=117/5
convert improper fraction to mixed numbers
23 2/5
Answer:
x=7
Step-by-step explanation:
8x +3 = 59
8x= 56
/8
x = 7
The formula for finding the height of an octagon from only one side is h=s(1 + the square root of 2). S is the length of one side. Your formula would be h=18(1 + the square root of 2).
h=18+18(the square root of 2)
h=18 + 25.4558
h=43.4558
Hope this helps!! :) And the decimal is rounded, just so you know ;). If your teacher likes everything in simplest radical form, then just don't convert the 18*the square root of 2 into a decimal and solve as you normally would.
