Answer:
20 + 3x ≥ 50
Step-by-step explanation:
After x days, John will have added 3x points to his total. The new total will be ...
20 +3x
We want that value to be at least 50, so we use the symbol "greater than or equal to" to express that relationship:
20 +3x ≥ 50

Brainly makes available a table of math symbols so you can choose the appropriate one to use in your expression. The number 2 is not the same as the symbol ≥. Using incorrect symbols makes it very difficult to tell what the intended problem is.

Answer:
Area of triangle= 35
x = 4
Step-by-step explanation:
The formula for area of rectangle = length x width.
Area of triangle = (1/2)bh
It's stated these two areas are equal:
(5)(3x - 5) = (1/2)(x + 3)(10)
Distribute on both the left side and the right side.
15x - 25 = (5)(x + 3)
15x - 25 = 5x + 15
Subtract 5x from both sides and add 25 to both sides.
10x = 40
Divide:
x = 4
Plug this back into the area of triangle:
= (1/2)(x + 3)(10)
= (1/2)(4 + 3)(10)
= (1/2)(7)(10)
= (1/2)(70)
= 35
