A piece of pipe is 303/4 inches long. If five pieces, each 41/3 inches long, are cut from the pipe, how many inches of pipe rema
galina1969 [7]
So, what is the total lenght of the pieces that wer cut off?

we multiply the lenght by the number:

4 \frac{1}{3}*5=20+\frac{5}{3}=21\frac{2}{3}

and we subtract this from the original pipe, that is

30\frac{3}{4}-21\frac{2}{3}

we need to bring the two fractions to the same denominator (by multiplying the fraction art in the first by 3 and 4 the second):

30\frac{9}{12}-21\frac{8}{12}=9 \frac{1}{12}

so the correct answer is D!

2.1(2.3 + 2.1x) = 11.65 + x. Step by step equation please help
DedPeter [7]

Answer:

x=2

Step-by-step explanation:

2.1(2.3 + 2.1x) = 11.65 + x

Distribute

4.83+4.41x=11.65+x

bring 4.83 over (-)

4.41x=6.82+x

bring x over

4.41x-1(x)=6.82

4.41-1=3.41 so

3.41x=6.82

divide 3.41

x=2
