Answer:
12 years
Step-by-step explanation:
Given that Mr. Hon purchases a new car every 4 years. Ms. Jasper purchases a new car every 6 years.
Assuming that they purchase new cars together after n years.
So, n must a multiple of 4 as well as multiple 6, i.e the number n is the lowest multiple (LCM) of 4 and 6.
As LCM od 4 and 6 is 12, so n=12.
Hence, after 12 years they will purchase news cars together.
Answer:
BCG =65
Step-by-step explanation:
DCG + GCB = DCB
We know BCG = 31x+3 and GCD = 12x+2 and BCD = 91
Substituting these in
12x+2 + 31x+3 = 91
Combine like terms
43x +5 = 91
Subtract 5 from each side
43x+5-5 = 91-5
43x = 86
Divide by 43
43x/43= 86/43
x=2
BCG = 31x+3
=31(2)+3
=62+3
=65
