Answer/Step-by-step explanation:
Given:
86.32947
Let's find the place value of each digit
8 => tens which is 80
6 => unit which is 6
3 => tenth which is 0.3
2 => hundredth which is 0.02
9 => thousandth which is 0.009
4 => ten-thousandths which is 0.0004
7 => hundred-thousandth which is 0.00007
If you add all of the it will give you 86.32947
Thus:
1. 6 => b
2. 8 => g
3. 4 => e
4. 7 => d (there's a mistake in the number of zeros written.)
5. 9 => c
Answer:
(2.4, -1.2)
Step-by-step explanation:
Start by moving the x and the y to the same side and moving the number across the equal sign in both equations. We should now have y-0.45x=-2.3 and 2y+4.2x=7.8. We can use the elimination method by multiplying the first equation by -2 to get -2y+0.9x=4.6 and 2y+4.2x=7.8. From there, add the two equations together, eliminating y (-2+2=0). We now have 5.1x=12.4; divide both sides by 5.1 to get x=2.4. Then, in any of the two equations, let's use y-0.45x=-2.3, substitute x with 2.4. Now we have y-1.08=-2.3. Add 1.08 to both sides to get y=-1.22; round that to the nearest tenth to get -1.2.
Answer:
36
Step-by-step explanation:
Hello,
If
it becomes

and 

So,

a = 1
b = 1
c = 17
d = 17
e = 0
Then a + b + c + d + e = 36
Thanks
Answer:
2c - 18x + 74/5
Step-by-step explanation:
<u>Step 1: Distribute
</u>
2(c + 7) - 18x + 4/5
(2 * c) + (2 * 7) - 18x + 4/5
<em>2c + 14 - 18x + 4/5
</em>
<u>Step 2: Combine like terms
</u>
2c + 14 - 18x + 4/5
<em>2c - 18x + 74/5
</em>
Answer: 2c - 18x + 74/5
