Answer:

h is 4.5

Step-by-step explanation:

$15 - 2h = 6$

make 2h the subject:

$- 2h = 6 - 15 \\ - 2h = - 9$

divide all sides by -2:

$\frac{ - 2h}{ - 2} = \frac{ - 9}{ - 2} \\ \\ h = \frac{9}{2} \\ \\ h = 4.5$

Cody's rent is increasing by $51 per month starting next year. That is an increase of 15% from his current monthly rent. Let r r

Inessa05 [86]

Answer:

$r = 43.35$

Step-by-step explanation:

Given

$Current\ Rent = r$

$Increment = 15\%$

$New\ Rent = \$51$

Required

Determine the value of r

The value of r can be set up percentage increase formula as follows:

$\%Increment = \frac{New\ Rent - Current\ Rent}{Current\ Rent}$

Substitute values in the above equation

$15\% = \frac{51 - r}{51}$

Cross Multiply

$51 - r = 15\% * 51$

Convert percentage to decimal

$51 - r = 0.15 * 51$

$51 - r = 7.65$

And the value of $r\ is\ calculated\ using:$

$r = 51 -7.65$

$r = 43.35$

Hence, Cody's current rent is $43.35 monthly

A cell phone costs $170 and has a tax rate of 7%. Write and Solve a proportion to find how much tax is paid on the cell phone.

Darina [25.2K]

Answer:

The Amount of tax paid on the cell phone is $11.9

Step-by-step explanation:

Given as :

The cost of the cell phone = x = $170

The tax rate of the cell phone = r = 7% of the phone cost

Let The Amount of tax paid on the cell phone = $y

Now, According to question

The Amount of tax paid on the cell phone = 7 % of cost of the cell phone

i.e y = 7% of x

Or, y = $\dfrac{7}{100}$ × x

Or, y = $\dfrac{7}{100}$ × $170

Or, y = $\frac{7\times 170}{100}$

∴ y = 7 × 1.7

i.e y = $11.9

So,The Amount of tax paid on the cell phone = y = $11.9

Hence, The Amount of tax paid on the cell phone is $11.9 Answer

Answer:

m = 3

n = 14

p = 2

Step-by-step explanation:

Given:

$\frac{7}{x}-\frac{3}{2}=\frac{n-mx}{px}$

We need to find the values of m, n, p

Solution:

We will first solve the L.H.S

L.H.S = $\frac{7}{x}-\frac{3}{2}$

Now we will first make the denominator common by taking L.C.M

$=\frac{7\times 2}{x\times 2}-\frac{3\timesx}{2\timesx}\\\\= \frac{14}{2x}-\frac{3x}{2x}$

Now the denominator is common hence we will subtract the numerators.

L.H.S $= \frac{14-3x}{2x}$

Now Comparing the the value of L.H.S with R.H.S we can say that;

$\frac{14-3x}{2x}=\frac{n-mx}{px}$

m = 3

n = 14

p = 2
