Answer: 7.3

Step-by-step explanation:

Do the parentheses first!

4-7= -3

Then, multiply -3 by 2

-3×2= -6

Next,

-6-6.7= -12.7

Then, add -12.7 to 20

-12.7+20=7.3

Your answer is 7.3

Compute the number of vinyl tiles, measuring 10 in. each side, needed to tile a kitchen measuring 20 ft. by 16 ft.

weqwewe [10]

(20*16 ft^2)(144 in^2/ft^2)(tiles/(10*10 in^2)

320ft^2(144in^2/ft^2)(tiles/100in^2)=460.8 tiles

However tiles are quantized integer units so 461 tiles will be needed to tile the kitchen.

For 20 Points. 3 Qs.<br> I also gave you guys a help sheet. PLEASE HELP.

Eduardwww [97]

Wat is help sheet, didn't help,

instructions unclear, got my calculator stuck in the ceiling fan

remember some simple exponential laws
$( x^{n} )(x^{m})=x^{n+m}$ and
$\frac{x^{n}}{x^{m}} =x^{ n-m }$
$x^{-m}= \frac{1}{x^{m}}$

first one
$(2^{-6})(2^{3})=2^{-6+3}=2^{-3}= \frac{1}{2^{3}} = \frac{1}{8}$

2nd one
$\frac{7^{5}}{7^{3}} =7^{ 5-3 } = 7^{2} = 49$

third one
$(3^{-4})(3^{2})=3^{-4+2}=3^{-2}= \frac{1}{3^{2}} = \frac{1}{9}$

dunno wat to do with 'help sheet'
