Answer:

Simplifying

10x + -2 = 118

Reorder the terms:

-2 + 10x = 118

Solving

-2 + 10x = 118

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + 10x = 118 + 2

Combine like terms: -2 + 2 = 0

0 + 10x = 118 + 2

10x = 118 + 2

Combine like terms: 118 + 2 = 120

Combine like terms: 118 + 2 = 12010x = 120

Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.

Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.x = 12

Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.x = 12Simplifying

Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.x = 12Simplifyingx = 12

y = total snow accumulated

x = hours

the ground has 0.2 inches of snow before the data starts

y = 1.5x+0.2

0 hours = x = 0, so y = 0.2 inches

after 9 hours, we predict that 13.7 inches of snow will have accumulated

y = 1.5(9)+0.2 = 13.7

How long will it take for the balance of an account to double if the savings account earns 0.75% annual interest compounded mont

Margarita [4]

You're looking for the time $t$ that it takes for the principal $P$ to double, so $A=2P$ . Dividing both sides of the formula by $P$ leaves you with

$2=\left(1+\dfrac rn\right)^{nt}$

You're given that the account earns 0.75% interest and that the interest is compounded monthly, so $r=0.0075$ and $n=12$ .

$2=\left(1+\dfrac{0.0075}{12}\right)^{12t}$
$\ln2=\ln\left(1+\dfrac{0.0075}{12}\right)^{12t}$
$\ln2=12t\ln\left(1+\dfrac{0.0075}{12}\right)$
$t=\dfrac{\ln2}{12\ln\left(1+\dfrac{0.0075}{12}\right)}\approx92.45$
