B. (n + 15) x 3--- That seems to be the correct answer. I hope I helped!
Answer:
x > -4
Step-by-step explanation:
Inequalities like these are solved the same way equations are solved, except when multiplying both sides you flip the less than/greater than sign:
3x + 7 > -x -9
3x + 7 - 7 > -x -9 -7 Subtract 7 from both sides
3x > -x -16
3x + x > -x -16 + x add x to both sides
4x > -16
>
divide both sides by 4
x > -4
In this case the inequality sign did not have to be flipped since we never multiply both sides by a negative number.
Answer:
Step-by-step explanation:
7. 1250 - 1050 = 200 remaining. so $ 200 split evenly between savings and entertainment.....means each gets $ 100.
what percent of her monthly budget will go towards savings ?
100 / 1250 = 0.08 = 8% <==
==================
luke spent 300 of his 375...
what percent did he not use...
(375 - 300) / 375 = 75/375 = 0.2 = 20% was not used <==
Let x represent the number of pounds of $10.75/lb coffee used in the mix.
.. 10.75x +3.25(100 -x) = 5.65*100 . . . . . . total cost of coffee blend
.. x(10.75 -3.25) = 100*(5.65 -3.25) . . . . . .separate x-terms from non-x terms
.. x = 240/7.5 = 32
32 pounds of $10.75/lb coffee should be used
68 pounds of $3.25/lb coffee should be used
