What is y in the equation 2/3 (2y+1) = 3/7 (2-y)

Alik [6]

Answer:

$y=\frac{4}{37}$

Step-by-step explanation:

$\frac{2}{3}(2y+1)=\frac{3}{7}(2-y)$

$\frac{4}{3}y+\frac{2}{3} =\frac{6}{7}- \frac{3}{7}y$

Add $\frac{3}{7}y$ on both sides and subtract $\frac{2}{3}$ on both sides.

$(\frac{3}{7}y- \frac{2}{3})+\frac{4}{3}y+\frac{2}{3} =\frac{6}{7}- \frac{3}{7}y+(\frac{3}{7}y- \frac{2}{3})$

$\frac{3}{7}y+\frac{4}{3}y=\frac{6}{7}-\frac{2}{3}$

Solve the fractions.

$\frac{(3)(3)+(7)(4)}{(7)(3)}y=\frac{(6)(3)-(7)(2)}{(7)(3)}$

$\frac{9+28}{21} y=\frac{18-14}{21}$

$\frac{37}{21}y =\frac{4}{21}$

Multiply by the reciprocal of the fraction with the variable to isolate the variable. The reciprocal is the inverted fraction.

$\frac{21}{37}*\frac{37}{21}y =\frac{4}{21}*\frac{21}{37}$

$y=\frac{4}{37}$

Can someone tell me what x equals

Troyanec [42]

X=22. The supplementary angle is 90°, so the 66° angle, plus (x+2) has to add up to 90° too.

3 1/3 feet are cut off a board that is 12 1/4 feet long.How long is the remaining

laiz [17]

Answer:

$8\frac{11}{12}$

Step-by-step explanation:

In order to answer this question you will have to subtract 3 1/3 from 12 1/4 by turning the mixed fractions into improper fractions, finding the common denominator, (CD) then subtracting the numerators.

$12 \frac{1}{4} - 3\frac{1}{3}$

Turn the mixed fractions into improper fractions:

$12\frac{1}{4} = \frac{49}{4}$

$3\frac{1}{3} = \frac{10}{3}$

$\frac{49}{4} -\frac{10}{3}$

Find the common denominator:

$4\times3=12$

$3\times4=12$

$CD=12$

$49 \times 3 =147$

$=\frac{147}{12}$

$10\times4=40$

$=\frac{40}{4}$

Now subtract the numerators:

$147-40=107$

$=\frac{107}{12}$

Turn the improper fraction into a mixed fraction:

$\frac{107}{12} =8\frac{11}{12}$

$=8\frac{11}{12}$

Hope this helps.
