Answer:
40 hollow blocks
Step-by-step explanation:
12/3= 4 hollow blocks per hour
10x4=40 hollow blocks in 10 hours
Answer:
P = - 3
Step-by-step explanation:
For the equation to have no solutions the the coefficient of x on both sides must be the same.
5 - 3x = Px + 7 ← P = - 3 , then
5 - 3x = - 3x + 7 ( subtract 5 from both sides )
- 3x = - 3x + 2 ( add 3x to both sides )
0 = 2 ← not possible
Meaning the equation has no solutions

When taking a polynomial modulo

, you reduce its terms' coefficients modulo

, so that, in conjunction with the result above,

For completeness, the linear term's coefficient should also get reduced in the same way as the constant term, so that
Answer:
4.5
Step-by-step explanation:
Graph y=3x then find two points from the graph, then find the distance between them two and round 4.47 to 4.5
