If you are solving for b:
-2.6b+4=0.9b-17 <subtract 4 from both sides
-4 -4
-2.6b =0.9b-21 <subtract 0.9b from both sides
-0.9b -0.9b
-3.5b = -21 <divide by -3.5
--------- ------
-3.5 -3.5
b=6
So, in this equation you're just plugging in I'm pretty sure. So x is -2 which is pretty self explanatory.. & y is 2. If you plug them in like so, your answer will turn out to be -6.
6(-2)+3(2)=-6
-12+6=-6
The answer should be -6 not -9.. so that was most likely a typo I'm pretty sure because the answer would not be correct as -9.
Answer:
x = 7
Step-by-step explanation:
<> sum of the interior angles of the polygon is (8-2)*180 = 1080°
<> since all the lengths are equal it implies all the angles are equal
<> there are 8 angles
=> 8(16x + 23) = 1080
=> 16x + 23 = 135
=> 16x = 135 - 23
=> 16x = 112
=> x = 112/16
=> x = 7

Answer:
50
Step-by-step explanation:
This is the equation:
x = 5 + 3y
We know that:
x - y = 35
Meaning we only need to solve for y now:
(5 + 3y) - y = 35
5 + 2y = 35
2y = 30
y = 15
Meaning the final formula is
x = 5 + 3(15)
x = 50
