Answer:
119/100 = 357/X
Step-by-step explanation:
since 357 is the price with the extra 19% tax, you can put 119 and 357 as numerators in a fraction because thats the price % of total cost with the tax, then have the denominators as the normal price without tax. so 119/100 bc 119 is the total cost % with tax, and 100 as the normal cost %. same for the opposite side, 357/X. 357 being the price with the tax and X being the price without the tax. so you just cross multiply to find X. so 100 × 357 (35,700) then divide the answer of that by 119 (35,700/119) to find X (300)
Answer:
see explanation
Step-by-step explanation:
To evaluate f(- x) substitute x = - x into f(x)
f(- x) = (- x)² + 2(- x) + 3 = x² - 2x + 3
-----------------------------------------------------
- f(x) = - (x² + 2x + 3) ← distribute parenthesis by - 1
= - x² - 2x - 3
-----------------------------------------------------------
- f(- x) ← substitute f(- x) from above
= - (x² - 2x + 3) ← distribute parenthesis by - 1
= - x² + 2x - 3
If you asking 2×7 then its 14 for each of them. 2 people for 7 instructors. But if your asking the probability its 28. I would like a little more question!!
Answer:
350
Step-by-step explanation:
divide 100/4= 25
25*3=75 so width = 75 meters
perimeter= 2(l+w)
perimeter= 2(100+75)
perimeter= 2(175)
perimeter= 350
