Answer:
2
Step-by-step explanation:
5x - 10 = 0
+10 +10
5x = 10
/5 /5
x = 2
well, if you add the numbers 3+1 you get 4. from this we know that there are 4 units total. 36÷4=9 so each unit is equal to 9. we can multiply 9•3 to get 27. there are 27 boys. we can multiply 9•1 to get 9 girls. subtracting 9 from 27, we get 18 more boys that girls.
y - 5 = 3/2(x + 3)
y - 5 = 3/2x + 9/2
y = 3/2x + 9/2 + 5
y = 3/2x + 19/2
<em>Equation</em><em> </em><em>of</em><em> the</em><em> line</em><em> </em><em>formula</em><em> </em><em>:</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>mx</em><em> </em><em>+</em><em> </em><em>c</em>
<em>#</em><em>S</em><em>o</em><em> </em><em>the</em><em> </em><em>slope</em><em> </em><em>(</em><em>m</em><em>)</em><em> </em><em>is</em><em> </em><em>3</em><em>/</em><em>2</em>

Answer:
x = 13.444 ... (repeating decimal) or;
x = 13 4/9
Step-by-step explanation:
-0.65 + 0.45x = 5.4
First we will add 0.65 to each 'side' of the equation.
0.65 + (-0.65) + 0.45x = 0.65 + 5.4
0.65 + (-0.65) = 0
0.65 + 5.4 = 6.05
Input the numbers, and now the equation looks like this:
0 + 0.45x = 6.05
Remove the zero:
0.45x = 6.05
Divide each 'side' by 0.45.
0.45x ÷ 0.45 = 6.05 ÷ 0.45
0.45x ÷ 0.45 = 1x = x
6.05 ÷ 0.45 = 13.444 ... repeating decimal
Input the numbers, and now the equation looks like this:
x = 13.444 ... repeating decimal
We can also write this as:
x = 13 4/9 in fraction form
