Solving a Basic Algebra Problem

Vamos resolver a questão dada na imagem. A questão diz que "Henry adiciona 5 a um número. Ele divide a soma por 2 e o quociente é 6". Seja \( x \) o número desconhecido. Então, a expressão para o problema é: \[ \frac{x + 5}{2} = 6 \] Para encontrar o valor de \( x \), siga os passos: <p>\( x + 5 = 6 \cdot 2 \)</p> <p>\( x + 5 = 12 \)</p> <p>\( x = 12 - 5 \)</p> <p>\( x = 7 \)</p> Portanto, o número desconhecido é 7.

Simple Multiplication Problem

<p>To solve the multiplication problem, multiply the two numbers:</p> <p>2 \times 9 = 18</p>

Calculating Percentage of One Number from Another Number

<p>Para encontrar el porcentaje que representa 129 sobre 860, divida 129 entre 860 y multiplique el resultado por 100.</p> <p>\(\frac{129}{860} \times 100 = x\)</p> <p>\(x = 15\% \)</p>

Solving a Simple Fraction Division Problem

<p>\[ \frac{5}{\text{RM}50} = \frac{5}{50} = \frac{1}{10} \]</p> <p>\[ \text{Thus, the result is } \frac{1}{10} \text{ or } 0.1 \]</p>

Simple Arithmetic Problems

<p>а) \( 55 - 47 = 8 \)</p> <p>б) \( 75 - 66 = 9 \)</p> <p>в) \( 84 - 78 = 6 \)</p> <p>г) \( 34 - 19 = 15 \)</p> <p>д) \( 27 + 18 = 45 \)</p> <p>е) \( 18 - 18 = 0 \)</p> <p>ж) \( 8 + 12 = 20 \)</p> <p>з) \( 5 + 30 = 35 \)</p>

Basic Arithmetic Problem on Summer Reading

<p>Let the total number of books Ada wants to read be \( T \).</p> <p>Let the number of books about cats be \( C \).</p> <p>Let the number of books about horses be \( H \).</p> <p>According to the problem, \( T = 12 \) and \( C = 5 \).</p> <p>To find \( H \), we subtract the number of books about cats from the total number of books:</p> <p>\( H = T - C \)</p> <p>\( H = 12 - 5 \)</p> <p>\( H = 7 \)</p> <p>Therefore, \( 7 \) books are stories about horses.</p>

Calculating the Number of Mollies in a Pet Fish Collection

<p>\text{Total pet fish} = 17</p> <p>\text{Goldfish} = 7</p> <p>\text{Let m be the number of mollies.}</p> <p>\text{Total pet fish} = \text{Goldfish} + \text{mollies}</p> <p>17 = 7 + m</p> <p>m = 17 - 7</p> <p>m = 10</p> <p>\text{Levi has 10 mollies.}</p>

Simple Addition Problem

<p>Um die Summe zu berechnen, addieren wir die Zahlen spaltenweise:</p> \[ \begin{array}{c@{\;}c@{\;}c@{\;}c} & 2 & 5 & 7 \\ + & 3 & 2 & 1 \\ \cline{1-4} & 5 & 7 & 8 \\ \end{array} \] <p>Daher ist \( 257 + 321 = 578 \).</p>

Simple Addition Problem

<p>3 + 3 = 6</p>

Solving a Basic Division Problem

<p>The given division problem is \( 214 \div 2 \).</p> <p>To solve for this, we perform long division:</p> <p>\( \begin{array}{r} 2\overline{)214} \\ \overline{-2} \\ \phantom{0}1 \\ \overline{-0} \\ \phantom{0}14 \\ \overline{-14} \\ \phantom{000}0 \\ \end{array} \)</p> <p>So the result of \( 214 \div 2 \) is \( 107 \).</p>

Simple Division and Multiplication Math Problems

这是一道简单的数学除法和乘法问题。 1. 对于第一个问题, \(58 \times b = 348\), 你需要找到 \(b\) 的值。 解这个问题我们需要使用除法: \[ b = \frac{348}{58} \] 计算出来得到: \[ b = 6 \] 2. 对于第二个问题, \(q + 7 = 36\), 你需要找到 \(q\) 的值。 解这个问题我们需要使用减法: \[ q = 36 - 7 \] 计算出来得到: \[ q = 29 \] 所以,\(b = 6\) 而且 \(q = 29\)。
