If x=15, y=3 & z=-2 what is the value of <br> x-y<br> _____+x ?<br> yz

Elodia [21]

Answer:

Step-by-step explanation:

From the question, the values of x, y and z are as follows.

x=15, y=3 and z= -2

Now, we are to find the value of the expression

$\frac{x - y}{yz} + x$

we substitute the values of x, y and z into the expression and simplify

$\frac{15 - 3}{3( - 2)} + 15$

$= \frac{12}{ - 6} + 15$

$= - 2+ 15$

$= 13$

Therefore, value of

$\frac{x - y}{yz} + x =12$

What equation results when you cross - multiply 17/d = 51/21

nekit [7.7K]

Answer:

$51d=357\\\\d=\frac{357}{51} \\\\d=7$

Step-by-step explanation:

A proportion is an equation that defines that two ratios are equal. When the terms of a proportion are cross multiplied, the cross products are equal. Cross multiplication is the multiplication of the numerator of the first ratio by the denominator of the second ratio and the multiplication of the denominator of the first ratio by the numerator of the second ratio:

$\frac{a}{b} =\frac{c}{d} \rightarrow ad=bc$

Therefore:

$\frac{17}{d} =\frac{51}{21} \\\\17*21=d*51\\\\357=51d\\\\Solving\hspace{3} for\hspace{3} d\\\\d=\frac{357}{51} \\\\d=7$
