We have from Thales theorem that because the 2 triangles are similar, JM/JK=JN/JL. We have that JN=x, JL=x+24 and that JM=7 and JK=28. Substituting, we get:
x/(x+24)=7/28.
Hence, x/(x+24)=1/4. This leads to 4x=x+24, 3x=24, x=8. We have solved for x=JN and this is equal to 8.
Answer:
Option D
x+4x>55
Step-by-step explanation:
Let the age of Julio be x
The age of Julio's father will be 4x
The sum of their ages is
x+4x
The sum is no less than 55 to mean it's greater than 55 hence
x+4x>55
The question is asking you to come up with a real-life example of something that can be represented as 15+ c= 17.50. If I were you I would do sales tax. You bought an item with a 15 dollar price tag, but when you go to check out 2.50 are added in tax to equal 17.50. to solve subtract 15 from 17.50: c= 2.50. Your variable (c) represents the sales tax. Hope that helps! :)
The expressions in which the numbers, or variables, or both, are connected by operational signs (+, - etc.) are called algebraic expressions. For example 5, 4x, a+b, x−y.
The tree weighs 12 pounds. Since the pot weighs 4 more than the tree, the pot weighs 16 pounds. This checks because 12+16=28.
