1 answer:

8 0

$\frac{1}{3} * (s-2)=s+4 \\ \\ \frac{s-2}{3}=s+4 \\ \\ s-2=3(s+4) \\ \\ s-2= 3s+12 \\ \\ s-3s=12+2 \\ \\ -2s= 14 \\ \\ \boxed{s= -\frac{14}{2}=-7}}$

Ryan is trying a low-carbohydrate diet. He would like to keep the amount of carbs consumed in grams between the levels shown in

nydimaria [60]

Answer:

$50$

Ryan would like to eat more than 50 carbs per day, but no more than 150 carbs per day.

So, Ryan's total carb intake must be between 50 and 150 carbs.

Step-by-step explanation:

So he wants to keep his consumption of carbs between the inequalities:

$110$

So, let's solve both inequalities.

$110$

Subtract 10 from both sides:

$100$

Divide both sides by 2:

$50$

$2x+10$

Subtract 10 from both sides:

$2x$

Divide both sides by 2:

$x$

So, our inequality is now:

$110$

Since we solved the equations:

$50$

Written as a compound inequality, this is:

$50$

In other words, Ryan would like to eat more than 50 carbs per day, but no more than 150 carbs per day.

So, Ryan's total carb intake must be between 50 and 150 carbs.

Ernie Rolph borrowed $3200 at 10% annual simple interest. If exactly 1 year later he was able to repay the loan without penal

Setler [38]

Answer:

$320

Step-by-step explanation:

From simple interest formular

A=P(1+int) where A is amount payable, P is principal amount borrowed and int is interest gained

int=Rt where R is rate of interest in decimal form, t is duration

The rate of 10% converted to decimal is 10/100=0.1

Substituting P for $3200, R for 0.1 and t for 1 year

A=$3200(1+(0.1*1))=$3200*(1+0.1)=3200*1.1=$3520

To find the interest, it's A-P hence $3520-$3200=$320

Therefore, interest owed is $320

Find the inverse of f(x)=2x-1

solong [7]

${ \qquad\qquad\huge\underline{{\sf Answer}}}$

Let's find the inverse of given function ~

$\qquad \sf \dashrightarrow \: f(x) = 2x - 1$

$\qquad \sf \dashrightarrow \: 2x = f(x) + 1$

$\qquad \sf \dashrightarrow \: x = \cfrac{f(x) + 1}{2}$

[ now, replace f(x) and x with $\sf{ {f}^{-1}(x)}$ ]

$\qquad \sf \dashrightarrow \: f {}^{ - 1} (x) = \cfrac{x + 1}{2}$

That's the required inverse function ~
