Answer: C) (9000x5) + (300x5) + (8~5) + (1x5)
Step-by-step explanation:
First Find what 9381 times 5 is.
9381x5=46108
Now Find out all the equations.
9000x5= 45000
300x5=1500
8-5=3
1*5=5
Now Add it all up.
45000+1500=46100
46100+3=46103
46103+5=46108
So, Your Answer is (C)
Your Welcome.
Answer: 19.20
Step-by-step explanation: What I did was figure out what 10% of 12 was (1.2) then multiplied it by 6 which was 7.2. Then I added that to 12 and got 19.2.
Let me know if this was helpful! :D
If you have at least as many equations as your have unknown variables, the 'system' is solvable (unless the equations are copies of eachother).
In this case, isolate one letter and plug it in the other. I'm going for the 2a in the bottom one (it doesn't matter)
2a - 4b = 12 => (divide by two and move the b's to the other side)
a = 6 + 2b. (plug this one into the top equation)
4(6+2b) + 6b = 10 => 24+8b+6b = 10 => 24 + 14b = 10 => 14b = -14 => b=-1
a = 6 + -2 = 4.
So a=4 and b=-1.
Answer:
f(x) = 12x - 4
Step-by-step explanation:
f(x)= 20 + 12(x - 2)
Distribute
f(x) =20 +12x - 24
Combine like terms
f(x) = 12x+20-24
f(x) = 12x - 4
Wow the answer is b because you secelted it
