You need 1.54g of calcium and magnesium. You need 1.49g of phosphorus and magnesium.
1/3 you simplify 3/18 to 1/6 then it then goes onto 1/3
Answer:
w = 5
Step-by-step explanation:
Combining like terms is a very important part to this equation!
<em>5.2w - 1.4 = 3.2w + 8.6</em>
<em>I added 1.4 to the right side first, though you must do it to the left side of the equation as well</em>
<em>5.2w - 1.4 + (1.4) = 3.2w + 8.6 + (1.4)</em>
<em>5.2w = 3.2w + 10</em>
<em>Combine the remaining like terms. I subtracted 3.2w from both sides. </em>
<em>5.2w + (-3.2w) = 3.2w + (-3.2) +10</em>
<em>2w = 10</em>
<em>Now divide</em>
<em>2w = 10</em>
<em>w = </em><em />
<em>w = 5</em>

a) 2/8 = 1/4
b) There are 3 females who can speak French and 2 males who can speak French, so the probability is 3/5
