The difference between two numbers is 5. three times the larger number is equal to four times the smaller number plus 6. what ar
UkoKoshka [18]
Let x and y represent the smaller and larger numbers, respectively.
  y - x = 5 . . . . . the difference is 5
  3y = 4x + 6 . . 3 times the larger is 4 times the smaller plus 6

Add x to the first equation to get an expression for y.
  y = x + 5
Use that in the second equation.
  3(x + 5) = 4x + 6
  3x + 15 = 4x + 6 . . . . . eliminate parentheses
  9 = x . . . . . . . . . . . . . . add -3x-6
  y = x+5 = 14

smaller number: 9
larger number: 14

Maude's living room is in the shape of a rectangle. Its dimensions are 21 feet by 14 feet. Find the length of the diagonal of th
DaniilM [7]
Use the pythagorean theorem A²+B²=C²

Use 21ft for A 
Use 14ft for B 
Then solve for C (the diagonal)

21²+14²=C²

441+196=C²

673=C²

√<u />673 = √C²

C≈25.24 or if you leave in radical form it is the square root of 637

There is an average of 3.5 x 10^−2 kilograms of dissolved salt in each liter of seawater. The South China Sea contains approxima
Fiesta28 [93]
Alright, since there's 3.5*10^(-2) of salt for each liter of seawater, that means that for each liter added we add that to it, meaning that we multiply the amount of salt per liter by the total amount of liters, resulting in 3.5*9.88*10^(-2)*10^18=34.58*10^16 (by adding -2 and 18 we get 16). Since we only want 1 number in front of the decimal (that's not a 0) for scientific notation, we can move the decimal one spot to the left to make it 3.458. However, we can't simply move the decimal without changing the exponent - since we moved it one to the left, we must increase the power from 16 to 17 (conversely, if it moved to the right, we'd decrease the power), resulting in 3.458*10^17
