It would appear your original equation is in Y=MX+b form, where M=2
Well u subtract -3then multiply so it's 3-3 (×-2) equals -3
Equilateral triangle<span> because</span><span> all three sides are equal.So</span><span> all three internal angles are also congruent to each other and are each 60 degrees
</span>
7x - 3 = 60
7x = 63
x = 9
if you need to find for y
11y + 5 = 60
11y = 55
y = 5
The first step is to calculate what fraction of the counters that Rob has.
Add all the portions together to find the total: 5+6+7= 18
Rob has 5 out of the 18, or 5/18, or 0.278
Next, do the same for the end ratio:
7+9+8= 24 and Rob has 7/24, or 0.292
By comparing his beginning portion (0.278) to his end portion (0.292) it is clear that he has a greater portion of the total counters. Given that the problem states that the number of counters stays the same, Rob must have more counters than he started with.
