Answer: 5: 7
Step-by-step explanation:
The total number for teacups: 2 yellow teacups + 5 brown teacups = 7 teacups
the ratio compares the number of brown teacups to the total number of teacups is :
5: 7
Answer:
Step-by-step explanation:
acute ks little angles
obtuse is big angles
in a riangle it adds up to 180
2/4 in simplest form:
First, to find the simplest form of a fraction, you'll need to find the greatest common factor (GCF). To do this, we can list the factors of 2 and 4 and find the first common one.
Factors of 2: 1, 2
Factors of 4: 1, 2, 4
Since 2 is our first common factor, it is our GCF.
Second, we can now take our GCF (2) and divide it with our numerator and denominator. We will get a new numerator and denominator.

Answer in fraction form:

Answer in decimal form:
Simplify √-y to √yi
3+ 2y = √yi
Square bot sides
(3 + 2y)^2 = -y
Expand
9 + 12y + 4y^2 = -y
Move all terms to one side
9 + 12y + 4y^2 + y = 0
Simplify 9 + 12y + 4y^2 + y to 9 + 13y + 4y^2
9 + 13y + 4y^2 = 0
Split the second term in 9 + 13y + 4y^2 into two terms
4y^2 + 9y + 4y + 9 = 0
Factor out common terms in the first two terms, then in the last two terms
y(4y + 9) + (4y + 9) = 0
Factor out the common term 4y + 9
(4y + 9)(y + 1) = 0
Solve for y
y = -9/4, -1
Check solution
when y = -9/4, the original equation; 3 + 2y = √-y does not hold true. We will drop y = -9/4 from the solution set.
Therefore,
<u>y = -1</u>
