Substitute -2 into negative 2Y minus 8X equals six

Answers

Answer 1
Answer:

When the value of x = -2 then, the value of y is 5.

When the value of y = -2 then the value of x is -0.25

Explanation:

Given:

-2y - 8x = 6

Considering x = -2

Then, we have to substitute the value of  x = -2 in the equation.

-2y - 8(-2) = 6

-2y + 16 = 6

10 = 2y

y = 5

So, when the value of x = -2 then, the value of y is 5.

Considering y = -2

Then, we have to substitute the value of  y = -2 in the equation.

-2 (-2) - 8x = 6

4 - 8x = 6

-2 = 8x

x = -0.25

So, when the value of y = -2 then the value of x is -0.25

There are 25 servings in a 30.2-ounce jar of peanut butter. How many ounces of peanut butter are there in 1

Answers

There should be 1.208 ounces of peanut butter in one serving. Since we are finding how many ounces in a serving, we divide from 30.2. 30.2 divided by 25 should be 1.208 ounces. :) I hope this helped
First, you divide 30.2 by 25. I'm sure your teacher wouldn't mind if you used a calculator for something like that.

We get 1.208, which can be rounded to 1.2 or 1.21. I'll say 1.21 because I like the hundredths place. XD

Now we know that each of the 25 servings are about 1.21 ounces of peanut butter. If you want to check your work if you didn't use a calculator, you can say, well, 1.21x25 is 30.25, which is very, very close to 3.2, and since we rounded, we can be sure the answer is correct.

Hope I helped!

Its simple just divide 108 and 6 which equals 18

When you add the same number to both sides of an inequality , does the inequality remain true

Answers

Yes, The Reason Why, Is If You Add The Same To Both Sides, It Still Remains True. For Example:
10*5+2 < 10*6
But, If You Add 6 To Both Sides:
10*5+8< 10*6+6.
It Is The Same As
50+8<60+6.
In Conclusion, This Means That As Long As You Add The Same Number To Both Sides, Not Just One, But Both Sides, Your Inequality Will Always Stay The Same! (Unless You Change Something That You Aren't Supposed To Like Making Is (10+6)*5+2 < 6*10+6)
It would be the same, because the number is the same, so an example:
4*3 and 5*3, it would be 12 and 15, but if you add 5 to each side, then it would be, 4*3+5 and 5*3+5, then you would get 17 and 20. So to answer the question, yes the inequality would remain true because the number that you are adding to each side is the same. It is the same with dividing and multiplying and subtracting.

Please help I only have today to do this type of work and I'm struggling!! Alice, Raul, and Maria are baking cookies together. They need cup of flour and cup of butter to make a dozen cookies. They each brought the ingredients they had at home. Alice brought cups of flour and cup of butter, Raul brought cup of flour and cup of butter, and Maria brought cups of flour and cup of butter. If the students have plenty of the other ingredients they need (sugar, salt, baking soda, etc.), how many whole batches of a dozen cookies can they make?
