X = 3

Explanation:
You want to isolate the 3. So you move 6x to the other side of the equal sign which makes it a negative now. Then you add -6x to 5x and you’re left with -x=-3. You never want your leading coefficient and variable to be negative (in this case -1x at the beginning) so you will divide both sides by -1 and get -3/-1 which simplifies to 3

Kia has 2 1/4 pounds of peppermint candies. She wants to put them in small bags, each about 3/8 of a pound . How many small bags

ololo11 [35]

Answer:

Step-by-step explanation:

When I am dealing with fractions I put them in money wise so 2 1/4 would be like 2.25 and 3/8 would be like 0.75.

So that means you divide 2.25 by 0.75 and that will give you three.

Therefore Kia can make 3 small bags of candies.

Perform the calculation then

Andru [333]

Answer:

416 (3 s.f.)

Step-by-step explanation:

To multiply decimals, begin by multiplying the numbers as if there is no decimal:

$\large\begin{array}{cccccc}&& 1 & 2 & 8 & 5\\\times && & 3 &2 & 4\\\cline{1-6} && 5 & 1 & 4 & 0\\&2&5&7&0&0\\3&8&5&5&0&0\\\cline{1-6}4&1&6&3&4&0\\\cline{1-6}^1&^1&^1&&\phantom{^{\frac{1}{2}}}&\end{array}$

Count the number of digits after the decimal point in each factor:

128.5 → 1 digit after the decimal point.
3.24 → 2 digits after the decimal point.

Therefore, there is a total of 3 digits after the decimal points.

Put the same number of digits after the decimal point in the product.

Therefore, the solution is to the multiplication is:

416.340

The factor with the fewest signification figures is 3.24.

This number has 3 significant figures.

Therefore, the solution to 3 significant figures is:

416 (3 s.f.)
