Answer:
-1
Step-by-step explanation:
It is negative 1 because the signs for the -3 are the same so you keep the -4, change the - to a +, then flip the negative 3.

For this case what you should do is the following system of equations:
x: skilled laborers
y: unskilled laborers
By writing the system we have:
x + y = 24
25x + 12y = 405
Solving the system:
Step 1:
-25x + -25y = -600
25x + 12y = 405
Step 2:
-13y = -195
y = 195/13
y = 15
step 3:
x = 24-y
x = 24-15
x = 9
Answer:
skilled laborers = 9
unskilled laborers = 15

we are given the measurement of the side of a square equal to 16 inches. The square when divided into two using a diagonal forms a 45-45-90 angle. This means this follows the Pythagorean theorem in which the diagonal is square root of 2 times the length of the sides of the square. In this case, the diagonal measures then 16sqrt2 inches
Answer:
The diameter is 3 inches
Step-by-step explanation:
If you are calculating a circle, one of the main rules you should know is that the diameter is double the radius. In this case the radius is 1.5 inches long. If you need the diameter, you need to double that figure; in this case the answer is 3 inches
