You need 1.54g of calcium and magnesium. You need 1.49g of phosphorus and magnesium.
The reason this is false is because the number you are subtracting with can be greater than the number your are subtracting from, resulting in a negative number. Or, if the order doesn't matter, the numbers can be the same. This results in a difference of 0, neither positive nor negative.

What is an equation?</h3>
- An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
- The word equation and its cognates in other languages may have subtly different meanings; for example, in French, an équation is defined as containing one or more variables, whereas in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign.
To find the value of t:
Given -
- (t+5)/(t-5) = 10
- t+5 = 10(t-5)
- t+5 = 10t - 50
- 10t - t = 5 + 55
- 9t = 55
- t = 55/9
Therefore, the value of t is (D) 55/9.
