Answer:
x > -99/4
Step-by-step explanation:
I must assume that you meant (-2/5)x -9<9/10.
This inequality has 3 terms. The LCD is 10. Multiply each term by 10 and reduce the result:
10(-2/5)x - 10(9) < 10(9/10), or:
-4x - 90 < 9
Adding 90 to both sides results in:
-4x < 99
Here we must divide by a negative number (that is, by -4). This requires reversing the direction of the inequality sign:
x > -99/4 is the final solution.
13/23% = 1300/23 (56.52)
<em>Therefore, 13 is 29% of 1300/23 (56.52)</em>
First we need to convert the mixed umber to an improper fraction...
3 2/9
Multiply the denominator by the whole number the. add the numerator the. put that over the original denominator.
9×3 = 27 + 2 = 29/9
now we can multiply the two fractions... numerator × numerator and denominator × denominator.
29/9 × 7/3 = 203/27
reduce the fraction to 7 14/27
