X and y represent the two students.

Teacher wants to spend at least $5 in each of x and y. That means x or y could be either equal to 5 or higher than 5.
x ≥ 5
y ≥ 5

Teacher only spends under $30. That means the sum of x and y couldn't be equal to higher than 30. It should be lower than 30.
x + y < 30

The correct answer is option D

Tasha is planning an expansion of a square flower garden in a city park. If each side of the original garden is increased by 5 m
Dmitry [639]

Answer:

9 m

Step-by-step explanation:

Let x be the original side of the square flower garden

We increase it by 5

The new side length is (x+5)

The area of a square is found by

A = s^2 where s is the side length

A = (x+5)^2

The area is 196

196 = (x+5)^2

Take the square root of each side

sqrt(196) = sqrt((x+5)^2)

14 = x+5

Subtract 5 from each side

14-5 = x+5-5

9 =x

The original side is 9 m

X –12 = -8x + 6 a.x = 2 b.x = -2 c.x = 3 d.x = -3
Naddik [55]

Answer:

<u>(a) x = 2</u>

Step-by-step explanation:

x - 12 = -8x + 6

First, move all the like terms to one side of the equation. We will move all the x's to the left, and the rest to the right in this equation. (Don't forget to pay attention to the signs of the numbers as you move them over the equal sign.)

x - 12 + 8x = 6

x + 8x = 6 + 12

9x = 18

Next, solve for x by isolating it to one side of the equation. Here, we'll have to divide 18 by 9 (do the opposite of what 9 is doing with x; instead of multiplying it with 18 like it currently is with x, divide 18 by it.)

x = \frac{18}{9}

x = 2

Therefore, your answer is (a), since x = 2.
