Answer: 45
<u>Step-by-step explanation:</u>
5 : 5 : 3 is simplified so it can be rewritten as 5x : 5x : 3x

Sara has 18 more than June --> 5x = 3x + 18
2x = 18
x = 9
In expanded form we have 5(9) : 5(9) : 3(9)
45 : 45 : 27

4 ft
It’s four feet because 4 is the constant or the y intercept. This means that when no action is done, it’s at four ft
Answer:
40 or 50%. Let me write this down and solve it, hold on a second.
Answer: x + 5 < 9
Step-by-step explanation:
A number: you can use any variable, such as an x.
Plus 5: plus means "+" and 5 is obviously 5.
Less than nine: less than means the number you wrote before has to be less than 9. You can use the "<" symbol for any equations that say "less than."
Answer:
x² +4x
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Given: base= 2x, height= x +4
Area of triangle
= ½(2x)(x +4)
= x(x +4)
= x(x) +x(4) <em>(</em><em>expand)</em>
= x² +4x
