Answer: r = -5/18
Step-by-step explanation: You solve -3(1+6r)+12=14
-3-18r+12=14 (When distributed)
-18r+9=14
-18r=5
r=-5/18
Answer:
100
Step-by-step explanation:
So in this problem, we have 5 base 10 blocks and 50 ones.
To find out the product we have to count by tens:
10, 20, 30, 40, 50
So 5 base 10 blocks = 50
Now we add the base ten blocks and the ones together:
50 + 50 = 100
So the answer is 100
Multiply 44 by 2.2 because 1 kg = 2.2 pounds.
44 * 2.2 = 96.8
The ratio is 96.8 milliliters per pound.
Hope this helps!
Answer:
2.6768·10^(-14) (Answer C)
Step-by-step explanation:
Problem 4: We ADD the powers of 10: 10^6·10^(-3) = 10^3. Also, 3.6·1.7 = 6.12. Therefore, Answer D is correct.
Problem 5: Again we ADD (combine) the powers of 10: 10^(-10)·10^(-5) =
10^(-15). 4.78·5.6 = 26.768. Our intermediary answer is thus:
26.768·10^(-15). This must be rewritten in the form x.xxxx, so here we have:
2.6768·10^(-14) (Answer C)
