solve each equation. Round your answers to the nearest ten-thousandth. Show your work please. Part 2A​
Reika [66]

Answer:

16. x = 3.0822, -3.0822

17. x = 1.6432, -1.6432

18. x = 1, -1

Step-by-step explanation:

16. log5[(4x²+2)/8] = 1

(4x²+2)/8 = 5¹

4x² + 2 = 40

4x² = 38

x² = 38/4

x² = 19/2

x = +/- sqrt(19/2)

x = 3.0822, -3.0822

17. log7[(2x²-4)(5)] = 1

10x² - 20 = 7¹

10x² = 27

x² = 2.7

x = +/- sqrt(2.7)

x = 1.6432, -1.6432

18. log5[(2x²+8)/2] = 1

x² + 4 = 5¹

x² = 1

x = +/-1

You brought 9 feet of elastic to make hair ties each hair ties need 3 3/8 inches of elastic how many hair ties can you make
PIT_PIT [208]

Answer:

32\ hair\ ties

Step-by-step explanation:

we know that

To make one hair ties is needed 3 3/8 inches of elastic

so

using proportion

Find out how many hair ties can you make with 9 feet of elastic

Remember that

1\ ft=12\ in

Convert 9 ft to inches

9\ ft=9*12=108\ in

Convert mixed number to an improper fraction

3\frac{3}{8}\ in=\frac{3*8+3}{8}=\frac{27}{8}\ in

using proportion

\frac{1}{(27/8)}=\frac{x}{108}\\\\x=108*8/27\\\\x=32\ hair\ ties
