Misha Larkins [42]

Answer:

there is not a complete question here ...

$\sqrt{2} +1$ is not in a denominator to rationalize

if it were you would multiply the rational expression (the fraction)

by $\frac{\sqrt{2} -1}{\sqrt{2} -1}$ the result (in the denominator would end up being "2 -1"

which is 1

Clark spent a total of $52 on a pair of shoes and a new jacket. The shoes cost $4 more than the jacket. Write a system of equati

lara [203]

Answer:

x+y=52
x-y=4
y=24

Step-by-step explanation:

The sum of the two costs is $52, so we can write ...

x + y = 52

The shoes cost $4 more than the jacket, so we can write ...

x - y = 4

These are your system of equations.

Subtract the second equation from the first:

(x +y) -(x -y) = (52) -(4)

2y = 48 . . . . . simplify

y = 24 . . . . . . .divide by 2

The cost of the jacket is $24.

Mariulka [41]

Answer:

9.42 years (= 113 months)

Step-by-step explanation:

Use the compound rate interest formula:

$A=P(1+\frac{r}{n})^{nt}$

where:

A = amount
P = principal
r = interest rate (in decimal format)
n = number of times interest is compounded per unit t
t = time

Given:

A = $7850
P = $5000
r = 4.8% = 0.048
n = 12
t = years

$\implies 7850=5000(1+\frac{0.048}{12})^{12t}$

$\implies 7850=5000(1.004)^{12t}$

$\implies \dfrac{7850}{5000}=(1.004)^{12t}$

$\implies 1.57=(1.004)^{12t}$

Take natural logs:

$\implies \ln1.57=\ln(1.004)^{12t}$

$\implies \ln1.57=12t\ln(1.004)$

$\implies t=\dfrac{\ln 1.57}{12 \ln1.004}$

$\implies t=9.42\textsf{ years (nearest hundredth)}$

$\implies t=113 \textsf{ months}$
