Answer: 6 + 3b ≥ 15 or the fourth one
Step-by-step explanation:
At most is $15 or more so that is equal to and greater than
She has already spent $6 so that's alone and she's gonna get b crackers for $3 each. To find the cost of <em>b </em>crackers you have to multiply <em>b </em>by 3 which is 3b.
Hope I helped!

Answer:
Solution: 
, 3.5, -15, 5
Not a solution: 129 and 
Step-by-step explanation:
20 ≥ 5 + 3x
3x + 5 ≤ 20
3x ≤ 20 - 5
3x ≤ 15
x ≤ 5
x must be LESS than or EQUAL to 5
by pythagorean formula, the last side is √(61)
by cos rule
cos A
A = 39.81
An equilateral triangle has three 60 degree angles.
The altitude divides it into two 30 60 90 triangles.
The altitude is the "middle side" of such a triangle.
When that is the case, the middle side divided by the square root of 3 = the short side and multiplied by (2/sq root (3)) equals the hypotenuse.
The hypotenuse is the side of the equilateral triangle.
So, 6 * 2 / (sq root of 3) =
