Carlos is 5 less than 3 times his brother's age. Carlos' age is also 11 years older than his brother's age. How old is Carlos?

mafiozo [28]

<h2>Systems of Equations Word Problems</h2>

To solve these questions, we can translate key words into operations.

<em>Older</em> = add
<em>Less</em> <em>than</em> = subtract

<h2>Solving the Question</h2>

We're given:

Carlos' age is 5 less than 3 times his brother's age
Carlos' age is 11 years higher than his brother's age

There are two variables present in this problem: Carlos' age and his brother's age.

Let Carlos' age equal <em>x</em>
Let his brother's age equal <em>y</em>

Translate the given information into equations:

Carlos' age is 5 less than 3 times his brother's age
⇒ $3y-5=x$
Carlos' age is 11 years higher than his brother's age
⇒ $y+11=x$

We can solve for <em>y</em>, his brothers age, using substitution:

$3y-5=y+11\\2y=16\\y=8$

Now, solve for <em>x</em> by substituting <em>y</em> in either of the equations:

$y+11=x\\8+11=x\\x=19$

Therefore, Carlos is 19 years old.

<h2>Answer</h2>

Carlos is 19 years old.

Surface area!!!!!!!!!!!!!!

gtnhenbr [62]

Answer:

D.347.45cm²

Step-by-step explanation:

The formula to find the surface area of a rectangular prism is:

$A=2(wl+hl+hw)$

Let's break down our variables:

Length = 11.73cm

Width = 9.08cm

Height = 3.23cm

Let's substitute the values:

$A=2)(9.08)(11.73)+(3.23)(11.73)+(3.23)(9.08))$

$A=2(106.508+37.888+29.328)$

$A=2(173.7247)$

$A=347.45$ cm²
