Answer:
4cm
Step-by-step explanation:
40÷10=4 and each dm is 10 km
To solve this equation, all you need to do is substitute the value of x that would be like this y = -2 (-3) -7 and solve, the answer would be -1.
A= 1
B= -5
C= 10
In order to figure it out, you can think about it like this..
400×10=4000
400×2=800
50×10=500
50×2=100
2×10=20
2×2=4
4000+800+500+100+20+4=5,424
Check answer by multiplying 452 and 12
452×12=5,424
Combine like terms: 18a - 8b -1
