Solve for x 4.72 = 3.25 + x

Anna [14]

Flip the situation:
X + 3.25 = 4.72

Subtract 3.25 from both sides
X + 3.25 - 3.25 = 4.72 - 3.25

X = 1.47

Answer:

Step-by-step explanation:

A scalar is a constant value that is multiplied throughout a matrix.

e.g.

In number 1 the set up would look like this

3 * $\left[\begin{array}{ccc}3&-1&5\\2&1&-4\\-6&3&2\end{array}\right]$

To solve this, you must distribute the 3 to each value within the matrix

The solution to #1 would be

M = $\left[\begin{array}{ccc}9&-3&15\\6&3&-12\\-18&9&6\end{array}\right]$

What does x and y =??????

Kazeer [188]

Answer:

x=30. y=60

Step-by-step explanation:

DG is a straight segment so it sums to 180 degrees. ECG is a right angle so 90 degrees. The rest is described as 2x and x. So 3x=90 degrees. x=30. Eh is also a straight segment. since we know x, we know that ECD is 60 degrees. So y+y=120 degrees. 2y=120. y=60.
