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.
