Solving for each variable ----- Let's see :)
12) Solve for d -Since you know that a variable next to a number means to multiply, we'll do the opposite since we have the unknown value -
12d = 216
<span>216 ÷ 12 = 18</span>
<span />d = 18
13) This one is a little different, since we have decimals.
71.5 = 5.5u
We still divide 71.5 by 5.5 and see what we get.
<span>71.5 ÷ 5.5 = 13 (A whole number)</span>
<span />u = 13
<span>14) Divide the first fractions numerator by its denominator - Leave out the variable.</span>
<span>5/6 = 0.83</span>
<span>Do the same to the other fraction</span>
<span>5/14 = 22.8</span>
<span>Divide your 2 decimals.</span>
<span>0.83 ÷ 0.22 = 3.77</span>
<span>x = 3.77</span>
<span>15) 44 = t/11</span>
<span>I think you would multiply 44 by 11 because since a fraction means to divide and we have an unknown value we do the opposite.</span>
<span>44 × 11 = 484</span>
<span>484 ÷ 11 = 44</span>
<span>t = 484</span>
<span>7.8x = 23.4</span>
<span>16) Divide each decimal to get what the value of x is</span>
<span>7.8 ÷ 23.4 = 3</span>
<span>x = 3</span>
<span>17) 53 = r/4</span>
<span>Multiply 53 by 4 to get what r is</span>
<span>53 × 4 = 212</span>
<span>r = 212</span>
<span>↑ ↑ ↑I hope all of this helped you!</span>
<span>TIP - If you want to check your work, make sure you just switch in the variables with the numbers I gave you! :D</span>
