D because the answer is 133
Answer:
a = -13/6
Step-by-step explanation:
Multiply both sides by the same number (15). This clears out the fractions:
-2a 13
15 -------- = 15 ----------
5 15
Then we have -2a(3) = 13, or
-6a = 13, or
a = -13/6

Answer:
$87.60
Step-by-step explanation:
Assuming that mary is on a fixed income rate, we can calculate that Mary is making approximately $5.84 per week.
17.50 / 3 = 5.833333.... -> <em>5.84</em>
Now we multiply this number by 15 to get the amount of money she saves over this time.
5.84 * 15 = <em>87.6</em>
<em>So, we can see that Mary has saved $87.60 in 15 weeks.</em>
Answer:
(5x -6)(5x +6) = 0
Step-by-step explanation:
Subtract 36 to put the equation in standard form. In this form, it looks like the difference of squares, so can be factored as such.
25x^2 -36 = 0
(5x)^2 -6^2 = 0
(5x -6)(5x +6) = 0
