A number is four times larger than the square of half the number

Mashcka [7]

Answer:

Step-by-step explanation:

Let the number = x

Read carefully the sentence part beginning with 4 times larger

4* something

4 times larger than the square of 1/2 the number

4 * (x/2)^2

4*(x/2)^2 = x

4*x^2/4 = x

x^2 = x be very careful how you handle this. It looks like 0 might be an answer, but it isn't. If you divide x on both sides and you allow 0, you will get 0 / 0 and that is undefined. You must exclude that possibility with some sort of statement.

x cannot be 0.

x^2/x= x/x

x = 1

2) -2(7n – 6) +n=-3 - 8n

iogann1982 [59]

Answer and Step-by-step explanation:

For this equation the answer is : $n=3$

Step 1 : Simplify both the sides of the equation :

$-2(7n-6)+n=-3-8n$

$(-2)(7n)+(-2)(-6)+n=-3+-8n$ (Distribute)

$-14n+12+n=-3+-8n$

$(-14n+n)+(12)=-8n-3$ (Combine the like terms)

$-13n+12=-8n-3$

Step 2 : Add " $8n$ " to both the sides :

$-13n+12+8n=-8n-3+8n$

$-5n+12=-3$

Step 3 : Subtract " $12$ " from both the sides :

$-5n+12-12=-3-12$

$-5n=-15$

Step 4 : Divide both the sides by " $-5$ "

$\frac{-5n}{-5} =\frac{-15}{-5}$

$n=3$

That's your final answer : $n=3$

Jenna uses 18 inches of ribbion for each box she wraps how many yards of rib ion does she need to wrap 4 boxes

Sav [38]

Hello Myeisha91!

First we need to find how many inches in total to wrap 4 boxes. We do that by multiplying 18 x 4 = 72 so Jena needs 72 inches. The question wants to know how many yards so we need to convert 72 inches into yards. We can convert inches to yards by using a conversion factor. We know that 1 inch = 0.0277778 yd. Now that we know 1 inch = 0.0277778 yd, lets convert the 72 inches to yards.

We convert 72 in to yards by multiplying 72 in by $\frac{0.0277778\;yd}{1\; in}$
$72\;in\times\frac{0.0277778\; yd}{1\;in} = 2\; yd$
So Jenna will need 2 yards to wrap 4 boxes.
