With a ratio, you should think of it in terms of a pie of sorts. In this example, the pie has 13 pieces, 9 of which consist of the perimeter of the large parallelogram and 4 of which consist of the perimeter of the smaller parallelogram. If we know that those 4 pieces of pie and equal to 20 units, then we would divide 20 by 4 to find the value of a single piece. 20/4=5 so a single piece of pie has a value of 5 units. We would then multiply 9 by 5 to find the value equivalent of the 9 pieces of pie. 9(5)=45. Therefore, the perimeter of the larger parallelogram is 45.
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.
