the wording is a little confusing so it could be either of these answers.

3x + 10 = 20

    -10.     -10

3x = 10

x = 10/3

3(x +10) = 20

3x + 30 = 20

   -30.     -30

3x = -10

x = -10/3

Answer:

The number is 10/3

Step-by-step explanation:

<u>Step 1:  Convert words into an expression</u>

Three times a number increased by ten is equal to twenty

(3n) + 10 = 20

<u>Step 2:  Subtract 10 from both sides</u>

3n + 10 - 10 = 20 - 10

3n = 10

<u>Step 3:  Divide both sides by 3</u>

3n / 3 = 10 / 3

n = 10/3

Answer:  The number is 10/3

Answer:

The number of years it will take for Yasemin's account balance to reach $1500 is 13.52 years.

Step-by-step explanation:

Where the model of the relationship between the time, t, in years, since the account was first opened and the and the balance in Yasemin's account is presented as follows;

B(t) = 1000 \times e^{(0.03 \times t)}

To find find out how many years it will take for Yasemin's account balance to reach $1500, we substitute B(t) = $1500 since we are told that after the years his account balance became $1500 as follows;

\$ 1500 = 1000 \times e^{(0.03 \times t)}

We now solve for t

\$ 1500 = 1000 \times e^{(0.03 \times t)}\\\\\frac{1500 }{1000 } =  e^{(0.03 \times t)}\\1.5 = e^{(0.03 \times t)}\\\\ln(1.5) = ln (e^{(0.03 \times t)})\\\\ln(1.5) = (0.03 \times t) \times ln (e)\\\\\therefore ln(1.5) = (0.03 \times t) \\\\t = \frac{ln(1.5)}{0.03 }  = 13.52 \ years

The number of years it will take for Yasemin's account balance to reach $1500 = 13.52 years.

1 1/5 divided by 2 1/6
andre [41]

3 11/30

steps to this: here you have to  Rewrite our equation with parts separated

=1+15+2+16

Solving the whole number parts

1+2=3

Solving the fraction parts

15+16=?

Find the LCD of 1/5 and 1/6 and rewrite to solve with the equivalent fractions.

LCD = 30

630+530=1130

Combining the whole and fraction parts

3+1130=31130

Solution by Formulas

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

65+136

Applying the fractions formula for addition,

=(6×6)+(13×5)5×6

=36+6530

=10130

Simplifying 101/30, the answer is

=31130
