Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define equation

0.8x = 7.2

Step 2: Solve for x

Divide both sides by 0.8: x = 9

Step 3: Check

Plug in x to verify it's a solution.

Substitute: 0.8(9) = 7.2
Multiply: 7.2 = 7.2

7.2 does indeed equal 7.2. ∴ x = 9 is a solution.

And we have our final answer!

erastovalidia [21]

Answer:

Find the slope:

$m = \frac{y2-y1}{x2-x1} = \frac{9 - 1}{-6 - 4} = -\frac{8}{10} = -\frac{4}{5}$

Use point-slope form and one of the points:

y - y₁ = m(x - x₁)
$y - 1 = -\frac{4}{5}(x - 4)$

Melissa used 4 cups of sugar to bake 54 cookies. If she’s only used 1 cup of sugar, what would be an equivalent ratio of cups to

daser333 [38]

Answer:

$\frac{2}{27}$

Step-by-step explanation:

We have given that melissa used 4 cups of sugar to bake 54 cookies.

That means 1 cup of sugar will be used to bake $\frac{54}{4}=\frac{27}{2}$ by unitary method

We have to find the ratio of cups to the cookies

We are using 1 cup of sugar

And cookies will be $\frac{27}{2}$

$\text{equivalent ratio}=\frac{1}{\frac{27}{2}}=\frac{2}{27}$

When calculating a loanâ€™s effective interest rate, if the nominal rate is 8. 5%, what value of i do you plug into your equatio

natta225 [31]

The nominal rate to plug in will be 0.085.

Given to us, the nominal rate is 8.5%,

The value to plug into your equation,

The equation can be simple interest or compound interest in both cases the value of the nominal rate to the plugin will be the same.

Thus, the nominal rate is 8.5% can be written as

$\begin{aligned}Nominal rate&= 8.5\%\\&= \dfrac{8.5}{100} \\&= 0.085\end{aligned}$

Hence, the nominal rate to plug in will be 0.085.
