Subtraction is finding the difference between two numbers whereas division is putting numbers into equal pairs or undoing multiplication ( if that helps ) So... If they say divide 6 by 2 they mean put six into equal pairs of 2 which would equal 3 E.g.:- ( there are 3 pairs of six cars in twos ) You can't use subtraction because that will just find the number difference of 6 and 2 which is 4 Hope that wasn't complicated

Please help me solve this problem!
damaskus [11]

Answer:

x = 200 packages.

B

Step-by-step explanation:

1 strip of tape = 2.375 inches

Each package requires 4 such strips or 4 * 2.375 which is 9.5 inches.

Set up a proportion for the rest of the problem

1 package / 9.5 inches tape = x packages / 1900 inches tape.

Multiply both sides by 1900

1*1900 / 9.5 = x

1900/9.5 = x

x = 200 packages.

The sum of two numbers is 65. The larger number is 23 more than the smaller number . What are the numbers ?
KiRa [710]
Let's represent the smaller number by x and the larger number x+23
x+x+23=65                                      x+23=21+23=44                                                                                                        So the two numbers are 21 and 44
2x+23=65
2x+23-23=65-23
2x=42
2x/2=42/2
x=21

Rudik [331]

Answer:

p = \sqrt{q +\frac{r}{t} }

Step-by-step explanation:

q=p^{2}- r÷ t   using BODMAS

q = p^{2} - (r/t)

q + r/t = p^{2}

p=\sqrt{q+\frac{r}{t} }
