How could you estimate the quotient 162 divided by 19
Answers
The exact quotient of 162 ÷ 19 is 8 with a remainder of 10.
To estimate the quotient of 162 divided by 19, you can use rounding or long division.
Rounding:
Round 162 to the nearest tens place, which is 160.
Round 19 to the nearest tens place, which is 20.
Divide 160 by 20: 160 ÷ 20 = 8.
So, the estimated quotient of 162 ÷ 19 is approximately 8.
Long Division:
Perform long division to find the exact quotient of 162 ÷ 19:
8
___________
19 | 162
- 152
-----

Blaine could make approximately 650 signs in forty hours.
Calculate the working hours
Blaine needs 14 hours to set up his work station. So, out of the total 40 hours, he will have
=> 40 - 14 = 26 hours to actually work on making signs.
Calculate the minimum number of signs he can make
If Blaine makes 16 signs per hour, then in 26 hours, he will make a minimum of
=> 16 * 26 = 416 signs.
Calculate the maximum number of signs he can make
If Blaine makes 23 signs per hour, then in 26 hours, he will make a maximum of
23 * 26 = 598 signs.
Calculate the average number of signs he can make
To get a more reasonable estimate, we take the average of the minimum and maximum number of signs:
Average = (Minimum + Maximum) / 2
= (416 + 598) / 2 = 650 signs.
Hence the correct option is (a).

a b/c= a + b/c=(a*c+b)/c
In this case:
7 5/6=7+ 5/6=(7*6+5)/6=(42+5)/6=47/6
Therefore: 7 5/6 =47/6
The fractional part of this number is what needs the focus. The whole number is 7, so we know that the decimal will lie somewhere between 7 and 8 (it will be 7 point something). All we have to do is convert 5/6 To decimal and attach it to the 7...
To find the decimal just do the math described by the fraction. 5/6 literally reads 5 ÷ 6. Set up the division and the result is .8333
So the decimal form of
7 5/6 is 7.8333
Alternatively you can set it up as a ratio then solve for x.
5/6 = x/100
Cross multiply
6x = 500
divide each side by 6
x = 83
83/100 = .83
7 5/6 = 7.83

-y + 12 = 4x
Solve with elimination
Answers
Then add the first equation to the second equation
4x +12 = -7y
-4x + 12 = y this eliminates the x's
24 = - 6y then divide by - 6
- 6 - 6
- 4 = y
So if you know that y = negative 4, you can substitute into either equation. I pick the second one because I am a lazy person.
-y + 12 = 4 x
-(-4) + 12 = 4 x combine your numbers
16 = 4 x then divide by 4
4 = x
So your solution is: x = 4 and y = -4 or this is also written (4, -4)
Does that work for you?
