What is 4/9(x+3)=g, solve for x?

Answers

$(4)/(9)(x+3)=g\ \ \ \ |multiply\ both\ sides\ by\ 9\n\n4(x+3)=9g\ \ \ \ |use\ distributive\ property:a(b+c)=ab+ac\n\n4x+12=9g\ \ \ \ |subtract\ 12\ from\ both\ sides\n\n4x=9g-12\ \ \ \ |divide\ both\ sides\ by\ 4\n\n\boxed{x=(9)/(4)g-3}$

$(4)/(9(x+3)) = g$

$(4(x+3))/(9) =g$

$4(x+3)=g*9$ $||Multiply- both -sides -by-\ \textgreater \ 9||$

$4(x+3)=9g$ $||Regroup -terms||$

$x+3= (9g)/(4)$ $||Divide- both -sides- by-\ \textgreater \ 4||$

$x= (9g)/(4) -3$

PLSSSS HELP IF YOU TULRY KNOW THISSS

Answers

Answer:

Step-by-step explanation:

Rearrange terms: -3x+4=6-3x

-3x+4=-3x+6

Subtract 4 from both sides

-3+4-4=-3x+6-4

Subtract the numbers

=3x==3x+2

Add 3x to both sides

=3x+3x=-3x+2+3x

-3x+3x=-3x+2+3x= 0=2 which is no solution

The areas of two similar polygons are in the ratio 64:81. find the ratio of the corresponding sides.

Answers

If the areas of two similar polygons are in the ration 64:81, then the ratio of their corresponding sides are $(8)/(9)$

What are polygons?

"A polygon, in geometry, any closed curve consisting of a set of line segments (sides) connected such that no two segments cross."

The simple polygons are triangles (3 sides), quadrilaterals (4 sides), and pentagons (5 sides).

Now if we take the given polygon as square (4 sides).

Then,

Let the sides of squares are a and b.

$(a^(2) )/(b^(2) )=(64)/(81) \n(a)/(b)=\sqrt{(64)/(81) } \n(a)/(b)=(8)/(9)$

Hence, the ratio of the corresponding sides of polygon is $(8)/(9)$

Answer is 8:9. The easiest example is a square. If the polygons are squares with areas of 64 and 81 then the sides of the squares are 8 and 9. Therefore, the ratio of the corresponding sides is 8:9

let m represent the number of Children playing soccer these Children are separated in to 4 equal teams write an expression for the number of Children on each team

Answers

m children are separated into 4 equal teams.

The number of children on each team:
$\boxed{(m)/(4)}$

Answer: m/4

Step-by-step explanation:

M represents the number of children so you would divide them into 4 groups
