Just plug in the numbers for the variables
$a. \: 1 + ( - 4) + ( - 3) \\ b. \: 1 + ( - 4) - (2 \times ( - 3)) \\ c. \: 1 + (3 \times ( - 4)) - (2 \times ( - 3))$
Does this help?

The length of an object in feet is equal to three times its length in yards. The length of a waterslide is 48 feet. Write and pi

zubka84 [21]

Answer:

Equation is: $L=3y$

Length in yards is 16 yards.

Step-by-step explanation:

Let 'L' represent length in feet and 'y' in yards.

Given:

Length of the waterslide is, $L=48\ ft$

Length in feet is three time its length in yards. Therefore,

Length in feet = 3 $\times$ Length in yards.

∴ $L=3y$

Dividing both sides by 3, we get:

$\frac{L}{3}=\frac{3y}{3}\\\\y=\frac{L}{3}$

Now, plug in 48 for 'L' and solve for 'y'. This gives,

$y=\frac{48}{3}\\\\y=16\ yards$

Therefore, the length of the waterslide of length 48 feet in yards is 16 yards.

Doreen Schmidt is a chemist. She needs to prepare 28 ounces of a 8% hydrochloric acid solution. Find the amount of 14% solution

scZoUnD [109]

Let, amount of 14% solution required is x ounces.

So, amount of 8% solution will be ( 28 - x ) ounces.

Now, mathematical equation is :

$\dfrac{14x}{100}+\dfrac{7(28-x)}{100}= \dfrac{8\times 28}{100}\\\\14x + 196 - 7x = 224\\\\7x = 28\\\\x = 4\ ounces$

Therefore, amount of 14% solution and 8% solution required is 4 ounces and 24 ounces respectively.

Hence, this is the required solution.
