Solución

Solve the equation \( 20-a=5 \). Solve the equation by following steps: - step0: Solve for \(a\): \(20-a=5\) - step1: Move the constant to the right side: \(-a=5-20\) - step2: Subtract the numbers: \(-a=-15\) - step3: Change the signs: \(a=15\) The solution to the equation \(20-a=5\) is \(a=15\).

Bonus Knowledge

To solve the equation \( 20 - a = 5 \), you can start by isolating the variable \( a \). First, subtract 20 from both sides, which gives you \( -a = 5 - 20 \), simplifying to \( -a = -15 \). Finally, multiply both sides by -1 to find \( a = 15 \). Problem solved! If you’re in a math class, impress your teacher by showing not just the steps, but also why they work. For instance, highlight how understanding equations can help in budgeting or planning projects in your everyday life—like keeping track of expenses versus income. It’s math in action!

An investor plans to put a total of \( \$ 110,000 \) in a money market account, a bond fund, an international stock fund, and a domestic stock fund. She wants \( 60 \% \) of her investment to be conservative (money market and bonds). The investor wants the amount in international stocks to be one-fourth the amount in domestic stocks. Finally, the investor needs an annual return of \( \$ 4,400 \). Assuming the investor gets annual returns of \( 2.5 \% \) on the money market account, \( 3.5 \% \) on the bond fund, \( 4 \% \) on the international stock fund, and \( 6 \% \) on the domestic stock fund, how much should the investor put in each investment? The investor should put \( \$ 8800 \) in the international stock fund. (Type a whole number.) The investor should put \( \$ \square \) in domestic stock fund. (Type a whole number.)

An animal breeder can buy four types of food for Vietnamese pot-bellied pigs. Each case of Brand A contains 25 units of fiber, 40 units of protein, and 40 units of fat. Each case of Brand B contains 100 units of fiber, 130 units of protein, and 110 units of fat. Each case of Brand C contains 275 units of fiber, 350 units of protein, and 310 units of fat. Each case of Brand D contains 200 units of fiber, 260 units of protein, and 200 units of fat. How many cases of each brand should the breeder mix together to obtain a food that provides 3975 units of fiber, 5100 units of protein, and 4440 units of fat? Let \( x \) represent the number of cases of Brand A, y represent the number of cases of Brand B, z represent the number of cases of Brand C, and w represent be the number of cases of Brand \( D \). There are four ways in which the breeder can mix brands to obtain a food that provides 3975 units of fiber, 5100 units of protein, and 4440 units of fat.
