Answer:
x = -5
Step-by-step explanation:
x + 115 = 110, they are acute to each other
∴ x = 110 - 115
x = -5
Answer:
Option a
Step-by-step explanation:
First multiply matrix A by -4.
Then multiply the matrix B by 6.
When multiplying a matrix by a number x you must multiply each element of the matrix by x.
Then we perform operation -4A
Now we perform operation 6B
Now we add the resulting matrices
Answer:
5.94
Step-by-step explanation:
Multiply 2.75 by $0.76 to get $2.09
Multiply 2.75 by $1.40 to get $3.85
Add $3.85 and $2.09 to get $5.94
The original equation we have is : <span>−x − 2y = −10
We need to isolate the x, which means that we need to get x alone on one side of the equation preferably in a positive form.
So, going back to the original expression:
</span><span>−x − 2y = −10
To make x positive, we will add x to both sides of the equation, thus, we get:
-2y = -10 + x
The next step is to eliminate the -10 from beside the x. To do this we will add 10 to both sides of the equation. When doing this we get:
x = -2y + 10
Based on this, the correct choice is A : -2y + 10</span>
Answer:
Not similar, one has 4 sides
