Answer:
225
Step-by-step explanation:
We can model this question with:
9 = 0.04x
x represents "what number."
0.04x = 9.
Divide 0.04 from both sides
0.04x ÷ 0.04 = 9 ÷ 0.04
9 ÷ 0.04 = 225.
Therefore, 9 is 4% of 225.
Answer:
The length of each red rod is 10 cm and the length of each blue rod is 14 cm
Step-by-step explanation:
Let
x ----> the length of each red rod in centimeters
y ----> the length of each blue rod in centimeters
we know that
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system of equations is the intersection point both graphs
using a graphing tool
The solution is the point (10,14)
see the attached figure
therefore
The length of each red rod is 10 cm and the length of each blue rod is 14 cm
Answer:
m>14 or m< -2
Step-by-step explanation:
Answer:
25 m = 25 × 100 = 2500 cm
5 ÷ 5 = 1
2500 ÷ 5 = 500
5:2500 ratio simplified is 1:500
Step-by-step explanation:
