2/3a - 2 =1/3 Find the answer for a. Show all work please

2/3a - 2= 1/3
add 2 to both sides
2/3a= 2 1/3
change mixed fraction to improper
2/3a= 7/3
divide both sides by 2/3
a= 7/3 ÷ 2/3
to divide fraction, multiply by reciprocal (inverse)
a= 7/3 * 3/2
a= (7*3)/(3*2)
a= 21/6
reduce by 3
a= 7/2 OR 3 1/2

ANSWER: 7/2 OR 3 1/2

Hope this helps! :)

2/3a - 2 = 1/3
2/3a = 2 + 1/3
2/3a = 7/3
a = (7/3) / (2/3)
a = (7/3) * (3/2)
a = 21/6
a = 7/2 ---- that is the answer

Hope this helps!

Answer:

No!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! NO NO NO NO NO... SEE BELOW!!!!!!

Step-by-step explanation:

LOL I like caps!!! and !'s

To question

If 5x3 is 5 $x^3$ then...

5x^3 times 2 equals 10x^3 no 10x^6

So the end result will be 10 $x^3\\$ + 9

What is the answer of this problem 8 (s+3)=72

Elden [556K]

First, distribute 8

8s+24=72

Now, isolate the variable with inverse operations

subtract 24 from both sides

8s=48

Divide by 8 on both sides

s=6

How many flyers can we buy?

Rudiy27

Answer: 1760

Step-by-step explanation:

Cost of 1 flyer = $0.25 or 25 cents

Budget is = $555

Let us assume that supplies cost is a one time cost

Cost of supplies for one time = $115

So budget remains =

So in $0.25 we get = 1 flyer

In $440 we get = = 1760

Hence, we can buy 1760 flyers.

I did 3 over 7 then 8 over x. I'm getting decimals. ‍♀️

Answer:

The length of side b is 9.

Step-by-step explanation:

Triangles are similar if they have the same shape, but can be different sizes.

When two figures are similar, the ratios of the lengths of their corresponding sides are equal.

If you know that two objects are similar, you can use proportions and cross products to find the length of an unknown side. We know that the triangle $ABC$ is similar to the triangle $XYZ$ . Therefore the following relation must be true:

$\frac{AB}{AC} =\frac{XY}{XZ}$

We know that side $AB$ is equal to 8, side $AC$ is equal to b, side $XY$ is equal to $2\frac{2}{3}$ , and side $XZ$ is equal to 3.

Substituting these values into the above relation and solving for b we get that:

$\frac{8}{b} =\frac{2\frac{2}{3} }{3}\\\\\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 2\frac{2}{3}=\frac{8}{3}\\\\\frac{8}{b}=\frac{\frac{8}{3}}{3}\\\\8\cdot \:3=b\frac{8}{3}\\\\24=b\frac{8}{3}\\\\8b=72\\\\b=9$
