Estimate 79% of 82 show work
Answer:96.34%
Solution for 79 is what percent of 82:
79: 82*100 =
(79*100): 82 =
7900: 82 = 96.34%
Answer:
64.72
79 percent *82 =
(79:100)*82 =
(79*82):100 =
6478:100 = 64.78
Now we have: 79 percent of 82 = 64.78

What is the value of b. If A+B=C and A=35 and C=25
Explain how you got this answer
Answer:
[tex]B=-10[/tex]
Step-by-step explanation:
Hi!
So let's write the equation again
[tex]A+B=C[/tex]
The next step is to plug in known values:
[tex]35+B=25[/tex]
Now we solve this as a normal algebra equation:
Do same to both sides
[tex]B = 25-35[/tex]
[tex]B=-10[/tex]

The property taxes on a home varies directly with the value of the home. Jack currently lives in a home worth $172,000 and pays $13,760 in taxes.
How much would someone pay in property taxes if they live in a $329,000 home in the same area?
Answer:
$26320
Step-by-step explanation:
Percentage solution with steps:
Step 1: We make the assumption that 172000 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100% = 172000.
Step 4: In the same vein, x% = 13760
Step 5: This gives us a pair of simple equations:
100% = 172000(1).
x% = 13760(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left-hand side) of both equations have the same unit (%); we have
100% / x% = 172000 / 13760
Step 7: Taking the inverse (or reciprocal) of both sides sides
x% / 100% = 13760 / 172000
=> x = 8%
Therefore, 13760 is 8% of 172000.
Now, I would multiply 329,000 by 8%(or 0.08) to get the answer 26320
Hope this helps!

He pays in property taxes $26320 if they live in a $329,000 home in the same area.
We have the following information available from the question is:
The property taxes on a home varies directly with the value of the home. Jack currently lives in a home worth $172,000 and pays $13,760 in taxes.
We have to find the how much would someone pay in property taxes?
Lets assume that:
The home worth cost is $172,000 is 100%
Let the property taxes be x
So, We equal to the value are:
$172,000 = 100%
Similarly, x% = $13,760
This gives us a pair of simple equations:
100% = $172000___(1).
x% = $13760___(2).
By simply dividing equation 1 by equation 2, we get:
100% / x% = 172000 / 13760
Taking the inverse (or reciprocal) of both sides sides
x% / 100% = 13760 / 172000
=> x = 8%
Therefore, 13760 is 8% of 172000.
They live in a $329,000 home in the same area, So
Multiply 329,000 by 8%(or 0.08)
=> 26320
