Answer:
Given
P( x) = 8x
R ( x) = 9x - 8
Step-by-step explanation:
<em>P(</em><em>x</em><em>)</em><em> </em><em>.</em><em> </em><em>R </em><em>(</em><em> </em><em>x</em><em>) </em>
<em>=</em><em> </em><em>8x </em><em>(</em><em> </em><em>9x </em><em>-</em><em> </em><em>8</em><em> </em><em>)</em>
<em>=</em><em> </em><em>72x</em><em>^</em><em>2</em><em> </em><em> </em><em>-</em><em> </em><em>64x</em>
It helps you narrow down to a smaller answer for example there is pi, (3.14159265359) and there is more and more to that number. It is now estimated to 3.14 because it would be almost impossible to work with pi if it wasn't estimated
Answer:
Step-by-step explanation:
2 1/2 + x = 5 1/3 Change the mixed numbers to improper fractions
5/2 + x = 16/3 The lowest common multiple is 6. Multiply by 6
5*3 + 6x = 16*2
15 + 6x = 32 Subtract 15 from both sides.
6x = 32 - 15
6x = 17 Divide by 6
6x/6 = 17/6
x = 2 5/6
Check
5/2 + 17/6 = 16/3
15/6 + 17/6 = 32/6
32/6 = 32/6 The question checks.
4. 1/3 6.-0.9 or -9/10 8. 2 1/3 10. -3.45 12.4.54 or 4 27/50
46 -2c
46 decreased by means 46 minus
Twice c would be c times 2
