This table shows the relationship of the total number of pieces of fruit to the number of bananas.
ddd [48]

Given:

The table that shows the relationship of the total number of pieces of fruit to the number of bananas.

To find:

Why is \dfrac{6}{5} not equivalent to \dfrac{3}{2}.

Solution:

If a, b, c are real numbers, then

\dfrac{a}{b}=\dfrac{a\times c}{b\times c}

The given fraction is \dfrac{3}{2}. It can be written as:

\dfrac{3\times 2}{2\times 2}=\dfrac{6}{4}

The number 3 is multiplied by 2 to get 6. So, the 2 should also be multiplied by 2. The ratio should be \dfrac{6}{4}, not \dfrac{6}{5}.

Therefore, the correct option is A.

If a rectangle has perimeter of 70 a length of x and a width of x-9, find the value of the length of a rectangle
iren2701 [21]

Answer:

length = 22

width = 13

Step-by-step explanation:

Perimeter of a rectangle is given by the formula

P =2(l+w)

we know the length is x

width is x-9

P =70

Substituting this into the equation

70 = 2(x+x-9)

Combining like terms

70=2(2x-9)

Distributing the 2

70 = 4x-18

Adding 18 to each side

70+18 = 4x-18+18

88 = 4x

Divide by 4

88/4 = 4x/4

22= x

we know the length is x

length = 22

width is x-9

width = 22-9= 13
