Solve for x. 9 4 13.5 x+4

Lady_Fox [76]

Answer:

x = 2

Step-by-step explanation:

The parallel lines divide the transversals into proportional segments, that is

$\frac{x+4}{13.5}$ = $\frac{4}{9}$ ( cross- multiply )

9(x + 4) = 54 ( divide both sides by 9 )

x + 4 = 6 ( subtract 4 from both sides )

x = 2

A piece of duct measures 48 inches. When pieces are fitted together, 1 72 inches is lost connecting each successive length of du

statuscvo [17]

Answer:

A piece of duct measures 48 inches.

In each connection, we lost 1.72 inches (it also could be 1/2 inches, but i will go with the other option)

Then:

If we have 7 pieces of duct connected we have 5 connections (the ones in the extremes are not connected between them)

So here we have 7 times 48 inches for the pieces, minus 5 times 1.72 inches for the connections, the length is:

L = 7*48in - 5*1.72in = 327.4 inches.

for the 12 pieces duct, we have 12 pieces and 10 connections, so the length is:

L = 12*48in - 10*1.72in = 558.8 in

Now, if we want to make only one duct with those two, then we must add their lengths, but if we connect them, we also need to subtract the 1.72in of the new connection:

L = 558.8 in + 327.4 in - 1.72in = 884.48 in

Use multiples to write two fractions equivalent to 7/9.

Nitella [24]

Answer:

$\frac{14}{18}$ , $\frac{21}{27}$

Step-by-step explanation:

To create equivalent fractions multiply the numerator and denominator of the fraction by the same multiples.

Using a multiple of 2, then

$\frac{7}{9}$ = $\frac{7(2)}{9(2)}$ = $\frac{14}{18}$

Using a multiple of 3, then

$\frac{7}{9}$ = $\frac{7(3)}{9(3)}$ = $\frac{21}{27}$
