Answer:
x = 42
Step-by-step explanation:
Cross multiplying is done as follows:
<em>the </em><em>denominator </em><em>of the second </em><em>fraction </em><em>is </em><em>multiplied </em><em>with the </em><em>numerator </em><em>of the first </em><em>equation</em> and <u>denominator of the first fraction is multiplied with the numerator of the second equation</u>
5(3x+6) = 4(4x-3) multiply inside the parenthesis
15x + 30 = 16x - 12 transfer like terms to same side of the equation
30 + 12 = 16x - 15x
42 = x
1 4/5 or 9/5 cups of flour because 4.5/2.5=1.8=9/5
Answer:
x = 6.3375

=> x = 6.3375
I would say that he divided each rectangle in 12 identical parts
for the first rectangle he shaded 1/3 of 12 = 4 parts
for the second rectangle he shaded 1/4 of 12= 3 parts
so 12= 3*4 leads to a minimum of 12 parts
