Add them all up so 2 6/12 and 1 6/12 is 4 and then add 1 9/12 to get 5 9/12 or in simple form 5 3/4

Which two expressions are equivalent for any value of y?
Harman [31]
The correct answer is letter d.

The reason is because of what each of these statements represent in math.

A number directly outside of a. parentheses means that we have that many groups of everything inside of the parentheses.

9(y + 3) means we have 9 groups of y and 9 groups of 3. This is the same as saying 9y + 27 or 27 + 9y.

How do I start This?

\bf \begin{array}{lccclll}
&\stackrel{lbs}{amount}&\stackrel{unit}{cost}&\stackrel{total}{value}\\
&------&------&------\\
Raisins&11&2.30&25.3\\
Peanuts&p&4.50&4.5p\\
------&------&------&------\\
mixture&m&3.29&3.29m
\end{array}

we know that, the mixture amount is the sum of 11 + p, or 11 + p = m.

we also know that, the total value is also a sum of 25.3 + 4.5p = 3.29m.

\bf \begin{cases}
11+p=\boxed{m}\\
25.3+4.5p=3.29m\\
----------\\
25.3+4.5p=3.29\left( \boxed{11+p} \right)
\end{cases}
\\\\\\
25.3+4.5p=36.19+3.29p\implies 1.21p=10.89\implies p=\cfrac{10.89}{1.21}
\\\\\\
p=\stackrel{lbs}{9}

Help pls I will give BRAINLY

Answer: The missing length is 16/3

Step-by-step explanation:

First, you have to find the proportional value between the two lengths on the first figure and the two lengths on the second figure.

The first figure’s lengths are 8 and 9, so the shorter length is 8/9 of the longer length.

Now apply the same proportional value to the second figure.

6 * 8/9 = 48/9

48/9 = 16/3

Can someone explain just 17-28??
Tatiana [17]

Answer:

you solve these by plugging the numbers into pythagorean theorem which is

a^2 + b^2 = c^2 (a squared plus b squared equal c squared)

C is the hypotenuse which is the longest side across from the right angel (assuming all these problems are for right triangles)

so 17 would be 9.5^2 + 3.8^2 = c^2

So 90.25 + 14.44 = c^2

104.69=c^2

Then to solve for c take the square root of each side and get

10.23=c

To do the other ones where a or b doesn’t have a value, it’s almost the same but you just have to plug in the variables in different places and solve it
