Perform the indicated operation 10ab/c^3d ÷ 15ab^3/7c^3d^4​
andrew11 [14]

Step-by-step explanation:

=  \frac{10ab}{ {c}^{3}d }  \div  \frac{15a {b}^{3} }{7 {c}^{3}  {d}^{4} }

=  \frac{10ab}{ {c}^{3} d}  \times  \frac{7 {c}^{3} {d}^{4}  }{15a {b}^{3} }

=  \frac{70ab {c}^{3} {d}^{4}  }{15a {b}^{3}  {c}^{3} d}

=  \frac{70}{15}  {a}^{1 - 1}  {b}^{1 - 3}  {c}^{3 - 3}  {d}^{4 - 1}

=  \frac{14}{3}  {a}^{0}  {b}^{ - 2}  {c}^{0}  {d}^{3}

=  \frac{14 {d}^{3} }{3 {b}^{2} }

A boy had a packet of 320 candies with 2 different flavours. 7/16 were orange flavour and the rest were lemon. He gave his frien
MrRa [10]

30 lemon candies he give his friend.

It is given that a boy had 320 candies. There were 2 flavors. 7/16 were orange flavor and the rest were lemon. He gave his friend 30 orange candies and some lemon ones.

320 (7/16)  =   140  were orange

320 - 140  =  180  were lemon

Let x be the number of lemon ones he gave  away

So,

[ 140 - 30 ]  / [ 180 - x ] =  11/15

110  =  (11/15) ( 180 - x )

(15/11) (110)  = 180 - x

150  = 180  - x

x = 180  - 150  =   30

Solve 4 over x minus 4 equals the quantity of x over x minus 4, minus four thirds for x and determine if the solution is extrane
lilavasa [31]
We mathematically express the given such that it becomes,
            4 / (x - 4) = x / (x - 4) - 4/3

To answer this, multiply the equation by 3(x - 4) since this is the least common multiple (LCM). 
     
             4(3) = (3)(x) - 4(x - 4)

Simplifying,
             12 = 3x - 4x + 16
             4 = -4x
The value of x should be equal to -1.  

The calculated value of y can be calculated.
