Activity 2: Translation A. Translate each into algebraic expressions. 1. x increased by 4 2. b more than 7 3. 4. half of x 5. thrice the sum of a number x and 10 the product of m and n *+4xt4 mtn A
To translate this phrase into an algebraic expression, we first need to recognize that "increased by" means addition. So, "x increased by 4" can be written as x + 4. This expression means that we're taking some value x, and then adding 4 to it.
2.b more than 7:
Similar to the first expression, "more than" implies addition. So, "b more than 7" can be written as b + 7. This expression means that we're taking some value b, and then adding 7 to it.
3.half of x:
This expression is a little trickier, but it means exactly what it says: we're taking half of the value x. Mathematically, this can be written as 0.5x or x/2. Both of these expressions mean the same thing: we're taking x and dividing it by 2.
4.thrice the sum of a number x and 10:
"Thrice" means three times, and "the sum of" implies addition. So, "thrice the sum of a number x and 10" can be written as 3(x + 10) or 3x + 30. Both of these expressions mean the same thing: we're taking some value x, adding 10 to it, and then multiplying the result by 3.
5.the product of m and n *+4xt4 mtn:
This expression is a bit unclear, but it seems to be asking for the product of m and n, multiplied by 4. This can be written as 4mn, where the order of the variables doesn't matter (multiplication is commutative).
Answers & Comments
Answer:
1.x + 4
2.b + 7
3.0.5x or x/2
4.3(x + 10) or 3x + 30
5.mn4 or 4mn
Step-by-step explanation:
1.x increased by 4:
To translate this phrase into an algebraic expression, we first need to recognize that "increased by" means addition. So, "x increased by 4" can be written as x + 4. This expression means that we're taking some value x, and then adding 4 to it.
2.b more than 7:
Similar to the first expression, "more than" implies addition. So, "b more than 7" can be written as b + 7. This expression means that we're taking some value b, and then adding 7 to it.
