Answer:

2 \frac{1}{2} or 2.5

Step-by-step explanation:

Convert mixed numbers to improper fractions:

\frac{40}{12} × \frac{9}{12}

Cancel the common factor (4):

\frac{10}{3} × \frac{9}{12}

Cancel the common factor (3):

\frac{3}{4} × \frac{10}{3}

Multiply fractions:

\frac{10 * 3}{3*4}

Cancel the common factor (3):

\frac{10}{4}

Cancel the common factor (2):

\frac{5}{2}

Convert improper fraction to mixed number:

\frac{5}{2} = 2 \frac{1}{2} or 2.5

The larger of two numbers is 15 more than 3 times the smaller number. If the sum of the two numbers is 63 find the numbers
scoray [572]

Answer:

X = 51

Y = 12

Step-by-step explanation:

2 numbers: (Larger) Number 1 is x and Number 2 is y

The equation is x + y = 63

  • x = 3y +15
  • y = y

New equation is:

  • 3y + 15 + y = 63

Combine like variables:

  • 4y + 15 = 63

Solve:

  • 4y + 15 - 15 = 63 - 15
  • 4y = 48

Divide 4 from each side:

  • <em><u>y = 12</u></em>

To find x fill in the variables from the 'x =' equation:

  • x = 3y + 15
  • x = 3( 12) + 15
  • <em><u>x = 51</u></em>
