Answer:
![\frac{2x^2-3x}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%5E2-3x%7D%7B7%7D)
Step-by-step explanation:
÷ ![\frac{7}{x^2}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7Bx%5E2%7D)
=>
× ![\frac{x^2}{7}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2%7D%7B7%7D)
=>
× ![\frac{x^2}{x}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2%7D%7Bx%7D)
=>![\frac{x(2x-3)}{7}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%282x-3%29%7D%7B7%7D)
=> ![\frac{2x^2-3x}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%5E2-3x%7D%7B7%7D)
30+30= 60 if A is 30 percent of 60 A=0.3 x 60
Answer:
1 ) 180 - 71 = 109
2) 5x +x = 180 ; 6x = 180 ; x = 180/6 = 30
3) 90
4) x + 6x+8 + x+12 = 180 ; 8x + 20 = 180 ; 8x = 160/8= 30
5) 180 -110 = 70
6) m = 180- 119 = 61
7) 90
8) 11y - 36 = 63 ; y = 99/11 = 9

(Q7) 180
(Q8) 2x+x = 3x = 90 ; x = 90/3 = 30
(Q15) 157
(Q16) 5x + 4 + (x-2) + (3x+7) = 180
9x +9 = 180 ; x = 171 / 9 = 19
I hope im right!!
On the face of it, [5.3%, 8.65%].
_____
If you mean that up to 8.65% may be added to the base 5.3% rate, then the total can be in the range [5.3%, 13.95%].
I can try to do my best
may i also receive brainliest on this one as well please?
