Answer:

x = - $\frac{7}{4}$

Step-by-step explanation:

Given

20x + 12 = 4x - 16 ( subtract 4x from both sides )

16x + 12 = - 16 ( subtract 12 from both sides )

16x = - 28 ( divide both sides by 16 )

x = $\frac{-28}{16}$ = - $\frac{7}{4}$ [ = - 1.75 ]

Given p : q = 5 : 2 and q : r = 4 : 3, find the ratio of p : q : r

yaroslaw [1]

Answer:

p : q : r = 10 : 4 : 3

Step-by-step explanation:

Expressing the ratio in fractional form

$\frac{q}{r}$ = $\frac{4}{3}$ ( cross- multiply )

4r = 3q ( divide both sides by 4 )

r = $\frac{3}{4}$ q = $\frac{3}{4}$ × 2 = $\frac{3}{2}$

Then

p : q : r

= 5 : 2 : $\frac{3}{2}$ ( multiply all parts by 2 )

= 10 : 4 : 3

What is the simple interest rate on a $2100 investment paying $1,559.46 interest in 15.8 years?

cluponka [151]

The simple interest rate is 4.7%

<h3>How to determine the simple interest rate?</h3>

The given parameters are:

Principal = $2100

Interest = $1,559.46

Time = 15.8 years

The simple interest is calculated as:

I = PRT

Make R the subject

R = I/(PT)

So, we have:

R = 1559.46/(2100 * 15.8)

Evaluate

R = 0.047

Express as percentage

R = 4.7%

Hence, the simple interest rate is 4.7%
