Answer:

A. 16

Step-by-step explanation:

We can use a ratio to solve

4 bracelets x bracelets

----------------- = -------------

12 minutes 48 minutes

Using cross products

4 * 48 = 12x

192 = 12x

Divide by 12 on each side

192/12 =12x/12

16 =x

Brenden Read 3/4 of a book that was 7/8 inches thick. How much of the book, in inches, did he read?

Firdavs [7]

Answer:

Step-by-step explanation:

To find how much 3/4 of a number is, multiply 3.4 by the number. Since the book is 7/8 inches thick, Brenden read 3/4 * 7/8.

To multiply fractions, multiply straight across numerator and denominator.

3/4 * 7/8 = 3*7/ 4*8 = 21/32

What are the potential solutions of log4x+log4(x+6)=2?

lions [1.4K]

The potential solutions of $log_4x+log_4(x+6)=2$ are 2 and -8.

<h3>Properties of Logarithms</h3>

From the properties of logarithms, you can rewrite logarithmic expressions.

The main properties are:

Product Rule for Logarithms - $log_{b}(a*c)=log_{b}a+log_{b}c$
Quotient Rule for Logarithms - $log_{b}(\frac{a}{c} )=log_{b}a-log_{b}c$
Power Rule for Logarithms - $log_{b}(a^c)=c*log_{b}a$

The exercise asks the potential solutions for $log_4x+log_4(x+6)=2$ . In this expression you can apply the Product Rule for Logarithms.

$log_4x+log_4(x+6)=2\\ \\ x*(x+6)=4^2\\ \\ x^2+6x=16\\ \\ x^2+6x-16=0$

Now you should solve the quadratic equation.

Δ= $b^2-4ac=36-4*1*(-16)=36+64=100$ . Thus, x will be $x_{1,\:2}=\frac{-6\pm \:\sqrt{100} }{2\cdot \:1}=\frac{-6\pm \:10}{2}$ . Then:

$x_1=\frac{-6+10}{2}=\frac{4}{2} =2\\ \\ \:x_2=\frac{-6-10}{2}=\frac{-16}{2} =-8$

The potential solutions are 2 and -8.

What is the difference of 7 1/6−3 5/8? fractions. with common denominators

lord [1]

Answer: 3 13/24

Step-by-step explanation:

Turn 7 1/6 into an Improper Fraction:

43/6 - 3 5/8

Turn 3 5/8 into an Improper Fraction:

43/6 - 29/8

Subtract:

43/6 - 29/8= 85/24

Turn 85/24 into a Mixed Number (Final Step):

85/24 = 3 13/24

Answer:

3 13/24
