BRAINLIEST AND FIVE STARS TO CORRECT ANSWER
Llana [10]
The answer is the first option, <-20, -42>.

We can find this by first finding what -2u would equal by multiplying <5, 6> by -2. This gives us <-10, -12>.

Then we need to find out what 5v is equal to, by multiplying <-2, -6> by 5 to get <-10, -30>.

Now that we know what -2u and 5v are, we can substitute them into the equation and get
<-10, -12> + <-10, -30>, which we can split up into -10 - 10 = -20, and -12 - 30 = -42, so your final answer is <-20, -42>.

I hope this helps!

You have one type of nut that sells for $4.50/lb and another type of nut that sells for $8.00/lb. You would like to have 28 lbs
-Dominant- [34]

Answer:

I will need 26.4 pounds of the expensive nuts and 1.6 pounds of the cheap nuts.

Step-by-step explanation:

Since I have one type of nut that sells for $ 4.50 / lb and another type of nut that sells for $ 8.00 / lb, and I would like to have 28 lbs of a nut mixture that sells for $ 7.80 / lb, to determine how much of each nut will I need to obtain the desired mixture, the following calculation must be performed:

8 x 0.95 + 4.5 x 0.05 = 7.825

8 x 0.94 + 4.5 x 0.06 = 7.79

0.94 x 28 = 26.32

26.4 x 8 + 1.6 x 4.5 = 218.4

218.4 / 28 = 7.8

Thus, I will need 26.4 pounds of the expensive nuts and 1.6 pounds of the cheap nuts.

Which of these non-terminating decimals can be converted into a ratinaol number
madreJ [45]

Answer

A. O.8743874374387438743....

Step by step explanation

Let's take a = O.8743874374387438743....

10a = 8.743874374387438743....

Similiarly,

10000a = 8743.874374387438743....

Since four decimal places are repeating.

Now subtract a from 10000a

10000 a - a = 8743.874374387438743....  - O.8743874374387438743....

9999 a = 8743

a = 8743/9999

8743/9999 = O.8743874374387438743....

That's it.

Hope you will understand the concept.

Thank you.
