First convert -5/6(b+1) to -5/6b-5/6 which looks like:
1/3b+2/3b-5/6b-5/6
second add 1/3b+2/3b=3/3b, convert to 6/6b so:
6/6b-5/6b-5/6
subtract 6/6b-5/6b = 1/6b so:
1/6b-5/6 is the answer
The director would have to pay $40.47.
If each scholar eats one slice of pizza, then there would be two pizza pies because 8 slices plus another 8 slices in 16
8+8=16
If all of them eat another .5 slice, adding up the halves would equal 8
.5 x 16 = 8
In total, the director would have to buy three pizzas which equals up to our total of $40.47
1600 is a double amount of 800, 800 of 80,000 is 1%, the property tax rate is 2%.
Answer:
13
Step-by-step explanation:
g(r)=25−3r
Let r=4
G(4)= 25 - 3(4)
= 25 -12
= 13

Three different interpretations of an 8% sales tax? Odd question.
8%, 8 percent, literally means "8 per 100". For each $100 item you purchase you pay an additional $8 in tax.
8% = 0.08, the factor applied to the price to determine the tax.
8%=8/100, you pay 8 cents in tax for every 100 cents in sales

Just because the ratio is 5:7 doesn't mean the total is 5+7=12. Non zero factors don't change a ratio, e.g. 5:7=50:70.

b/g=5/7
The fraction of boys is b/(b+g) which if you've done these a few times you can immediately write down as 5/12. Let's solve it like its our first time,
![g = \frac 7 5 b](https://tex.z-dn.net/?f=g%20%3D%20%5Cfrac%207%205%20b)
![\dfrac{b}{b+g} = \dfrac{b}{b + \frac 7 5 b} = \dfrac{1}{1 + \frac 7 5} = \dfrac{1}{\frac{12}{5}} = \dfrac{5}{12}](https://tex.z-dn.net/?f=%5Cdfrac%7Bb%7D%7Bb%2Bg%7D%20%3D%20%5Cdfrac%7Bb%7D%7Bb%20%2B%20%5Cfrac%207%205%20b%7D%20%3D%20%5Cdfrac%7B1%7D%7B1%20%2B%20%5Cfrac%207%205%7D%20%3D%20%5Cdfrac%7B1%7D%7B%5Cfrac%7B12%7D%7B5%7D%7D%20%3D%20%5Cdfrac%7B5%7D%7B12%7D)
Similarly the fraction of girls is 7/12.
