Jeff drinks 2/3 of a glass of juice. write a fraction that is equivalent to 2/3

Answers

some fractions that are equivalent to 2/3 are 4/6 and 6/9
to find equivalent fractions, you just have to reduce the fraction or multiply both the top and bottom numbers by the same number to increase the fraction.
2/3 is as reduced as it can be, though.

7y^2+18y+22=6y^2+34y-41

Answers

Solve for y over the real numbers:

7 y^2 + 18 y + 22 = 6 y^2 + 34 y - 41

Subtract 6 y^2 + 34 y - 41 from both sides:

y^2 - 16 y + 63 = 0

The left hand side factors into a product with two terms:

(y - 9) (y - 7) = 0

Split into two equations:

y - 9 = 0 or y - 7 = 0

Add 9 to both sides:

y = 9 or y - 7 = 0

Add 7 to both sides:

Answer: y = 9 or y = 7

the sum of a negative number, 1/4 of the negative number, and 7/16 of the negative number is -13 1/2. what is the negative number. ok now how do u solve that and what is the answer?

Answers

k so ur gonna hav x + 1/4x + 7/16x =-13 1/2. Start with that then you need to add the lil terms together. Thats x, 4/16 x (so it can be added easier) and 7/16 x added together. So you get 1 11/16x = -13 1/2. Use a calculator for that and you get x = -19.63636364

Answer:

-8

Step-by-step explanation:

According to question,

(-x) + (-x)(1/4) + (-x)(7/16) = -13 1/2

-x - x/4 -7x/16 = -27/2

Now, make all denominators equal:

(-16x -4x - 7x)/16 = -27/2

Now, multiply both sides with 16 to get rid of denominator:

-16x - 4x - 7x = -216

-27x = -216

-x = -216/27

= -8
