Answer:
6
Step-by-step explanation:
770:5 or 154:1
154 km per hour
Use PEMDAS
20 * 20/5 + 100 - 50
Multiply and divide first
20 * 20 = 400
400/5 = 80
Add 100 and then subtract 50
80 + 100 = 180
180 - 50 = 130
130 is the answer.
Answer:
0.0001
Step-by-step explanation:
2 x 10 x 0.0001 equals 0.0002. If you want confirmation do on a calculator
In the first equation, we have 3y. In the second equation we have y.
If we multiply the second equation by 3, then if we subtract both the equations, we will be able to eliminate y.
If we multiply the second equation by -3, then if we add both the equations, we will be able to eliminate y.
The answer to your question is: 3 and -3.
