12. It's similar to having an infinite number of solutions because there isn't a specific solution to answer the question.
13. For the equation 0.9x + 5.1x - 7 = 2(2.5x-3), there is only one solution and it is x=1
14. The error that your friend made was that she added extra 16x to the equation. the correct answer is that there is no solution.
16. the equation 6 (x+2)= 5 (x+7) has only one solution. it is x=3.
sorry i wasn't able to answer the other 3,

Answer:
2,111.15 cm³
Step-by-step explanation:
The solid is made up of 2 cones.
Volume of the solid = volume of cone of the two cones
✔️Volume of cone 1 = ⅓πr²h
r = ½ of 24 = 12 cm
h = √(13² - 12²) = 5 cm
Volume of cone 1 = ⅓×π×12²×5 = 753.98 cm³
✔️Volume of cone 2 = ⅓πr²h
r = ½ of 24 = 12 cm
h = √(15² - 12²) = 9 cm
Volume of cone 1 = ⅓×π×12²×9 = 1,357.17 cm³
✔️Volume of the solid = 753.98 + 1,357.17 = 2,111.15 cm³
Im not sure the question. negative 58 divided by 910 is -0.0637, but that isnt an answer choice.
Answer:
18%
Step-by-step explanation:
From adjusted gross income of $100,000, subtract the standard deduction of $6,350 and a single personal exemption of $4,050. That makes taxable income equal to $89,600. That amount is just below the upper end of the 25% tax bracket, with the tax calculation amounting to $18,138.75. That works out to an effective tax rate of 18%.
Well, we can simplify 5/10 down to 1/2. See how the top number is the half of the bottom number? You just do the same thing and you get 3/6.
Good luck!
