Write an expression using the distributive property that can be used to find the quotient of 126 divided by 7
mina [271]
Well, let's discover how many times 7 goes into 126 first.

7 x 11 = 77
7 x 12 = 84
7 x 13 = 91
7 x 14 = 98
7 x 15 = 105
7 x 16 = 112
7 x 17 = 119
7 x 18 = 126

Well, 7 goes into 126 - 18 times - therefore the quotient is 18. The use of the distributive property wouldn't be necessary.

Nevertheless, you could say that:

\frac { 126 }{ 14 } \\ \\ =\frac { 140-14 }{ 7 } \\ \\ =\frac { 140 }{ 7 } -\frac { 14 }{ 7 } \\ \\ =20-2\\ \\ =18

* I've used the distributive property above.

Dr. Leonard sells by

= 60%,

The mark up value will be:

= \frac{1200000\times 60}{100}

= 720,000 ($)

hence,

The selling price he should put with the bank will be:

= Project \ cost+Mark \ up \ value

You mean find the elephant's weight on Pluto?

100:3 & 4100:x

4100/100 = 41
3*41 = 123

The ratio would become 4100:123 with the elephant's weight on Pluto as 123 pounds.
