Answer:

e

Step-by-step explanation:

let x be the number of one- bedroom and y the number of two - bedroom apartments , then create 2 equations and solve simultaneously.

x + y = 12 ( subtract y from both sides )

x = 12 - y → (1)

360x + 450y = 4950 → (2)

substitute x = 12 - y into (2)

360(12 - y) + 450y = 4950 ← distribute parenthesis and simplify left side

4320 - 360y + 450y = 4950

4320 + 90y = 4950 ( subtract 4320 from both sides )

90y = 630 ( divide both sides by 90 )

y = 7

there are 7 two- bedroom apartments

Write a matrix equation for the given systems of equations.
REY [17]

Answer:

<em></em>\left[\begin{array}{ccc}2&-6&2\\0&3&-2\\0&2&2\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right]= \left[\begin{array}{ccc}1\\-5\\-3\end{array}\right]<em></em>

Step-by-step explanation:

Given system of equations are

2x-6y-2z = 1

3y - 2z = -5

2y + 2z = -3

given

2 x - 6 y - 2 z = 1

0 x + 3 y - 2z = -5

0 x +2y + 2 z = - 3

<em>The Matrix form of the given system of equations </em>

<em>A X = B</em>

<em></em>\left[\begin{array}{ccc}2&-6&2\\0&3&-2\\0&2&2\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right]= \left[\begin{array}{ccc}1\\-5\\-3\end{array}\right]<em></em>

Grant needs 2/3 cup of raisins and 3/4 cup of almonds to make trail mix, which statement can be used to find out if their are mo
mina [271]
To solve this problem, you must find a common denominator. First, you multiply the denominators together, then, multiply the numerator of the first fraction by the original denominator of the second fraction and vis-versa. 

3*4 = denominator of both
2*4 = numerator of first fraction
3*3 = numerator of second fraction

Your fractions should end up being 8/12 cups of raisins and 9/12 cup of almonds. You can now compare these fractions. 

Overall, there are 1/12 more almonds than raisins.
