Answer:

To add or subtract some rational numbers, you have to change the rational numbers so they have a common denominator. When you have a common denominator, you can then go on with the addition or subtraction on the numerator part.

Answer:

To add or subtract these rational numbers, you first need to change your rational numbers so that they share a common denominator. Once you have a common denominator, you can then go ahead with the addition or subtraction of just the numerator part

SOS i need helppp!! i'm not good at math just reading and science!!!
Viktor [21]

I got 45 for x and 135 for z.

X and 3x are supplementary (they equal 180) x+3x=180 — 45+3(45)=180

Then x and z are also supplementary x+z=180 — 45+z=180

(45-45)+z=180-45

Z=135

Sorry if this is wrong. I did my best, hope it helps

A spinner is divided into 6 equal sectorslabeled 1-6. Grace spun the spinner threetimes. What is the probability that the sum of
S_A_V [24]

Solution

Sample\text{ }Space=6^3=216

To find the probability of less than 13 or greater than 15

\begin{gathered} Possible\text{ outcome for 13}=(6,6,1),(6,5,2),(6,4,3),(5,5,3),(5,4,4) \\ Total\text{ Number of Outcomes}=3+3!+3!+3+3=21 \\  \\ Possible\text{ Outcome for 14}=(6,6,2),(6,5,3),(6,4,4),(5,5,4) \\ Total\text{ number of possible outcomes}=3+3!+3+3=15 \\  \\ Possible\text{ Outcome for 15}=(6,6,3),(6,5,4),(5,5,5) \\ Total\text{ number of possible outcomes}=3+3!+1=10 \\  \\ Overall\text{ Total}=21+15+10=46 \end{gathered}

Therefore, the probability that the sum of her spins is less than 13 or greater than 15 is

\begin{gathered} p=1-\frac{46}{216} \\  \\ p=\frac{170}{216} \\  \\ p=\frac{85}{108} \end{gathered}
