I hope this helped I've only done part A
Answer:
30 and 33 years
Step-by-step explanation:
Let Lara be x years
Cam =x+3
x+x+3=63
2x+3=63
2x=63-3
2x=60
x=60/2
x=30
Lara=30years and Cam =30+3+33years
No. It means that you should find a integer to divide 32 47 80 , and the equals must be integer also. But the 3 numbers have no common factor
The answer is the first option, <-20, -42>.
We can find this by first finding what -2u would equal by multiplying <5, 6> by -2. This gives us <-10, -12>.
Then we need to find out what 5v is equal to, by multiplying <-2, -6> by 5 to get <-10, -30>.
Now that we know what -2u and 5v are, we can substitute them into the equation and get
<-10, -12> + <-10, -30>, which we can split up into -10 - 10 = -20, and -12 - 30 = -42, so your final answer is <-20, -42>.
I hope this helps!
This system will have 1 solution, or C. That's because since the equations are different, meaning that there is 1 solution.
