1. <span>-0.9x+2.8=4.1
First subtract 2.8 from both sides.
-0.9x = 1.3
Now divide both sides by -0.9.
x = -1.4444..
This can be rounded to -1.44
</span><span>c) -1.44
2. Jordan has 650 pennies. He'll give 85 to his brother and split the rest with his sister.
</span>d) 85+2x=650
Answer:
B 1 1/7
Step-by-step explanation:
- 9 2/7 - ( -10 3/7)
We know subtracting a negative is like adding
- 9 2/7 +10 3/7
10 3/7 - 9 2/7
Putting this vertical
10 3/7
-9 2/7
-----------------
1 1/7
The answer to the monthly payment is $257.1428571 or $258.
How to get the answer:
Simply minus $5555 to $555. You get $5000.
Then, divide $5000 to the number of payments which is 42. (5000/42)
For that, you get a total of 119.047619. But that is not the final answer yet.
Next, we will multiply 119.047619 to 12, because we are looking for the monthly payment and we were given an "annual" rate. Annual means yearly and every year we have twelve (12) months. In that case, 119.047619 multiplied by 12 is equal to 1428.571428. Still, it is not the final answer.
The last step is, we will multiply the answer 1428.571428 to 18% or .18 and we get a total of 257.142857. Since we used the unit $ then we will a dollar for the answer. Completing the answer to the ]question, we get a total of $257.142857 or $258 for the monthly payment.
Step-by-step explanation:
just count off the positions after the decimal point.
they go with decreasing negative exponents of ten.
the first position is 1/10.
the second 1/100.
the third 1/1000.
the fourth 1/10000
the fifth 1/100000
and that is how we can easily convert such decimals into fractions.
0.63333 = 63333 / 100000
or were you looking for the infinite decimal ?
that would be 1.9/3 = 19/10 / 3 = 19/30
I found this by simply suspecting that there is a division by 3 involved (due to the 3333333 repeating pattern).
so, by multiplying 0.63333 by 3 we get 1.9.
1.9 = 19/10
and then dividing by 3 gives us 19/30
