When a sign has the underline, it means it is also equal to.
for example,
x $\geq$ 10
so the solution for "x" is greater than or equal to 10

Grains of sand are very small, there being about 3000 grains in one cubic centimeter (cm3) of sand. A cm3 is a small cube measur

Anastasy [175]

Answer:

The value is $x = 3.000 * 10^9 \ grains$

Step-by-step explanation:

From the question we are told that

$1m^3 = 10^6 cm^3$

And that

$3000 \ grains \ of \ sand \ is \ in \ 1cm^3$

So the number of sand grain that is in $1m^3$ is mathematically evaluated as

$x = 3000 * 10^6 \ grains$

=> $x = 3.000 * 10^9 \ grains$

Solve for x. The number that is cut off is 14. Suppose that both figures are similar.

Mekhanik [1.2K]

Since both rectangles are similar, the following ratio must be fulfilled:

$\frac{x+9}{14}=\frac{9}{6}$

By multiplying both sides by 14, we get

$\begin{gathered} x+9=\frac{9\times14}{6} \\ x+9=21 \end{gathered}$

and by subtracting 9 to both sides, we have

$x=12$

Therefore, the answer is 12.

Please help, answer must be in fraction form if possible

yuradex [85]

Answer:

28.875 or 28 7/8

Step-by-step explanation:

pls mark brainliest!

steps:

(23+1/2) + (15+1/8) - (9+3/4) then solve

46+1 over 2 + 120+1 over 8 - 36+3 over 4

solve

47/2 + 121/8 - 39/4

solve

188+121-78 over 8 = 231/8

convert 231/8= 28 7/8
