Step-by-step solution for: Writing Algebraic Expressions Worksheets - Math Monks
To solve the problem, we need to translate each phrase into an algebraic expression. Let's go through each one step by step:
---
- "Fifty-seven subtracted from \( z \)" means we start with \( z \) and subtract 57.
- Algebraic expression: \( z - 57 \)
---
- "The total of sixty and a number \( r \)" means we add 60 to \( r \).
- Algebraic expression: \( 60 + r \)
---
- "The product of \( x \) and twenty-two" means we multiply \( x \) by 22.
- Algebraic expression: \( 22x \)
---
- "The difference between eight and a smaller number \( x \)" means we subtract \( x \) from 8.
- Algebraic expression: \( 8 - x \)
---
- "Twenty-eight more than a number \( j \)" means we add 28 to \( j \).
- Algebraic expression: \( j + 28 \)
---
- "A number \( y \) raised to the power of 8" means we raise \( y \) to the exponent 8.
- Algebraic expression: \( y^8 \)
---
- "The ratio of \( y \) to 5" is \( \frac{y}{5} \).
- "The sum of the ratio of \( y \) to 5 and 4" means we add 4 to \( \frac{y}{5} \).
- Algebraic expression: \( \frac{y}{5} + 4 \)
---
- "The sum of \( x \) and 4" is \( x + 4 \).
- "One-fourth of the sum of \( x \) and 4" means we take \( \frac{1}{4} \) of \( x + 4 \).
- Algebraic expression: \( \frac{1}{4}(x + 4) \)
---
- "The difference between \( x \) and a smaller number 3" is \( x - 3 \).
- "Five times the difference between \( x \) and 3" means we multiply \( x - 3 \) by 5.
- Algebraic expression: \( 5(x - 3) \)
---
- "The quotient of 2 divided by 5" is \( \frac{2}{5} \).
- "\( p \) reduced by the quotient of 2 divided by 5" means we subtract \( \frac{2}{5} \) from \( p \).
- Algebraic expression: \( p - \frac{2}{5} \)
---
- "Two-sixths of a number" means \( \frac{2}{6} \) of the number. Simplifying \( \frac{2}{6} \) gives \( \frac{1}{3} \).
- "Two-sixths of a number decreased by 7" means we subtract 7 from \( \frac{1}{3} \) of the number.
- Algebraic expression: \( \frac{1}{3}x - 7 \)
---
- "One-fourth of \( z \)" is \( \frac{1}{4}z \).
- "One-fourth of \( z \) subtracted from 19" means we subtract \( \frac{1}{4}z \) from 19.
- Algebraic expression: \( 19 - \frac{1}{4}z \)
---
Here are all the algebraic expressions:
1. \( z - 57 \)
2. \( 60 + r \)
3. \( 22x \)
4. \( 8 - x \)
5. \( j + 28 \)
6. \( y^8 \)
7. \( \frac{y}{5} + 4 \)
8. \( \frac{1}{4}(x + 4) \)
9. \( 5(x - 3) \)
10. \( p - \frac{2}{5} \)
11. \( \frac{1}{3}x - 7 \)
12. \( 19 - \frac{1}{4}z \)
\[
\boxed{
\begin{aligned}
1. & \ z - 57 \\
2. & \ 60 + r \\
3. & \ 22x \\
4. & \ 8 - x \\
5. & \ j + 28 \\
6. & \ y^8 \\
7. & \ \frac{y}{5} + 4 \\
8. & \ \frac{1}{4}(x + 4) \\
9. & \ 5(x - 3) \\
10. & \ p - \frac{2}{5} \\
11. & \ \frac{1}{3}x - 7 \\
12. & \ 19 - \frac{1}{4}z
\end{aligned}
