3/4 of a meter in decimal form is 0.75m

1/3 of a meter in decimal form is 0.33m

 Only two whole pieces measuring 0.33 can be cut from the ribbon since

0.33 + 0.33 = 0.66 (which is 0.09 less than 0.75) 

therefore any other piece will measure  0.75 - 0.66 = 0.09

For simplicity we can multiply by 100 to convert meters to cm, so

0.75 * 100 = 75cm,  0.33 * 100 = 33cm,  0.66 * 100 = 66 cm,  0.09  * 100 = 9cm.

So  two ribbons each 33cm long, totaling 66cm ,can be cut from the 75cm ribbon and only 9cm of the ribbon will be left.

Help pls!<br> simplify<br> -6 x^{2} ÷ 12 - 2(-7)<br><br> a. -17<br> b. 35<br> c. -35<br> d. 11
Mariana [72]

Answer:

11

Step-by-step explanation:

Given: \frac{-6^{2}}{12} -2(-7)

Using PEDMAS rule to solve it.

Now, simplifying:

We first open parenthesis which is (-7) = -7

= \frac{-6^2}{12}-2\times -7

Now, we evaluate the exponent which is -6^2=-36

Next, we divide -36 by 12 to get -3

= \frac{-36}{12}-2\times -7 \\= -3 -2\times -7

Next, we multiply -2 and -7 to get 14

= -3 + 14

Lastly, we add -3 and 14 to get 11

= 11

∴ Answer is 11
