Answer:
c = 8x-30
23x-90
Step-by-step explanation:
Since the cost of soda is x, 8 times the cost of soda is is 8x.
Then, you have to take 30 cents away, so the cost for pizza would be 8x-30 or 8x-.30.
This is your pizza or c.
Next, to put in 3 pizzas and 5 sodas, you just multiply 3 and 5 by the corresponding variables.
So 3(8x-30) + 5(x) = 18x - 90 + 5x = 23x - 90 or 23x - .90
Isolate the variable by dividing each side by factors that don't contain the variable.
a=- \frac{ x^{2}- \sqrt{( x^{3} + x^{2} b+12x-72(x-2)-2x} }{x-2} ,- \frac{ x^{2}+ \sqrt{( x^{3} + x^{2} b+12x-72(x-2)-2x} }{x-2}
Solve for b by simplifying both sides of the equation then isolating the variable.
b= \frac{12}{x}+ \frac{72}{ x^{2} }-2+2a- \frac{4a}{x}+ \frac{ a^{2} }{x}- \frac{2a^{z} }{ x^{2} }
Hopefully i helped ^.^ Mark brainly if possible. Lol once again i saw the same question so why not answer it again!
Answer:
she did not get at least 2100 and definitely not 85% of the worth
Step-by-step explanation:
3000*0.85=2550
3000*0.7=2100
First we multiply the numbers ignoring the decimal and then place the decimal in the position
3.04 *7.091 = 2155664
Now the first number has two digits after the decimal and the second number has three digits after the decimal.
Therefore in the final result we have to move the decimal (2+3) =5 place from the left,
So the answer would be 21.55664
So, the correct answer is 21.55664
Jerry calculated the answer correctly , but made an error in the placement of the decimal point. The answer is not reasonable because 2.155664 and 21.55664 mean two completely different answer far apart from each other
Hope this helps but I this helps but I think the answer is D if not then try B
