Answer:

Your correct answer is -81/10

Step-by-step explanation:

$\frac{5}{100}- (8.1 + \frac{5}{100})$

= $\frac{1}{20} - (8.1 + \frac{5}{100})$

= $\frac{1}{20} - (8.1 + \frac{1}{20})$

= $\frac{1}{20} -\frac{163}{20}$

$=\frac{-81}{10}$

A jar of marbles contains 7 blue marbles, 12 yellow marbles, 8 green marbles, and 5 red marbles. Use this information to answer

Total marbles = 7 + 12 + 8 + 5 = 32
Green marbles = 8
Yellow marbles = 12

P(green ,then yellow) = (8/32)(12/32) = 3/32

Answer: The probability is 3/32

I would appreciate if you answered!

Answer:

None of those options

Step-by-step explanation:

I just did the work myself and even ran it through a calculator but the correct answer isn't one of those options. Here's my work:

$-\frac{5}{6} =z+\frac{1}{8}\\-\frac{5}{8}-\frac{1}{8}=z\\-\frac{40}{48}-\frac{6}{48}=z\\-\frac{46}{48}=z\\-\frac{23}{24}$

I'd contact you teacher about that...it might be an error in their system (it's happened to me a few times before where the correct answer is marked as incorrect or isn't even an option)

Does anyone knows how to do that? <br> I need to solve for x

Answer:

$x=17$ °

Step-by-step explanation:

Because the diagonal lines are marked with arrows, we know that they are parallel. The two angles that are marked with measures are same-side interior angles. Same-side interior angles of parallel lines are supplementary, meaning that the sum of their measures is $180$ °.
