Answer:

there are two terms which means it is a binomial algebraic expression

Step-by-step explanation:

the first term is -9

and the second term is 5.5

note:be aware that the negative sign is there in the first term and the reason that we didn't put the negative sign in the second is because there is no negative sign before 5.5 .

Someone please help!!! VERY URGENTTT
katovenus [111]

Answer:

1/9

Step-by-step explanation:

For these questions, you have to first find the probability of each event individually occuring then multiply these two probabilities together. So, lets first find the probability of Event 1 occuring (rolling a number higher than 1). On a dice, we know that there are 6 numbers (1, 2, 3, 4, 5, 6) of which the numbers 5 and 6 are higher than 4. Therefore, the proability of Event 1 occuring is 2/6 = 1/3. Now, we find the probability of event 2 occuring.

We know that there are 3 options on the spinner that the arrow can land on. It is also evident that they all have the same chance of landing on it. Therefore, the possibility is 1/3.

Now that we have both of our probabilities, we multiply the answer together.

Therefore, our answer will be:

1/3 x 1/3, which gives 1/9.

Solve -5y+6=-9 pls help me with this
alexandr402 [8]

Answer:

-5y + 6 = -9

y = 3

Step-by-step explanation:

subtract 6 from both sides

-5y + 6 - 6 = -9 - 6

simplify

-5y = -15

divide both sides by -5

(-5y)/5 = (-15)/5

simplify

y = 3

janice invests a total of 8000 in two different accounts. the first account returns 5%, while the second account returns 8%. if
Zinaida [17]

Answer:

"She invested $2500 in 5% account and $5500 in 8% account"

Step-by-step explanation:

Let the amount invested in 5% account be "x"

So, the amount invested in 8% account would be "8000 - x"

Interest amount is the percentage multiplied by amount invested. So

Interest of 5% account = 5% of x = 0.05x

Interest of 8% account = 8 % of 8000 - x = 0.08(8000 - x)

Total interest is the sum of these 2 expressions that EQUATES to 565 (given). Let's solve for x:

0.05x + 0.08(8000 - x) = 565\\0.05x+640-0.08x=565\\0.03x=75\\x=2500

and thus,

"8000 - x" = 8000 - 2500 = 5500

Hence,

She invested $2500 in 5% account and $5500 in 8% account
