Answer:

1. 2x - 5

2. 5(x + y)

3. (5 - x)²

Step-by-step explanation:

1. Five less than the twice the number

Let the number be 'x'. 5 less than twice the number = 2x - 5

2. Five times the sum of two numbers

Let the two numbers be 'x' and 'y'. Then the notation would be: 5(x + y)

3. The difference of 5 and a number, squared

Let the number be 'x'. The mathematical expression for the above statement would be: (5 - x)².

Which of the following is the solution for 7 - 4x ≥ 35 ?
melamori03 [73]
There are no solutuons listed (says which of the following). My answer below should be in the list to choose from.

7 - 4x ≥ 35
subtract 7 from both sides

-4x ≥ 28
divide both sides by -4 AND change the direction of the inequality sign because we're dividing by a negative

x ≤ -7

CHECK:
7 - 4x ≥ 35
7 - 4(-7) ≥ 35
7 + 28 ≥ 35
35 ≥ 35

ANSWER: x ≤ -7

Hope this helps! :)
