The algebraic expression of the situation above is 4x - 100 = 400
<h3>How to form an algebraic expression?</h3>
Let
the amount of ice cream they serve in July = x + 100
the amount of ice cream they serve in June = x
They served twice as many customers in august as they did in June.
Therefore,
the amount of ice cream they serve in August = 2(x)
the amount of ice cream they serve in August = 2x
Therefore,
2x + x + x + 100 = 400
4x - 100 = 400
4x = 500
x = 500 / 4
x = 125

I’m pretty sure it would be 15 because the formula for the area of a square is width x height so since it’s a square all side are the same so width is 5 and height is 5 so 5x5=15 hope it helps
The inequality can be used to determine how many months will it take for Caroline's hair to be at least as long as Trinity's hair is (1/5)x + 7 ≥ (1/10)x + 10
<h3>What is an
equation? </h3>
An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
Let x represent the number of months.
For Caroline's hair:
Length = (1/5)x + 7
For Trinity's hair:
Length = (1/10)x + 10
For Caroline's hair to be at least as long as Trinity's hair, hence:
(1/5)x + 7 ≥ (1/10)x + 10
The inequality can be used to determine how many months will it take for Caroline's hair to be at least as long as Trinity's hair is (1/5)x + 7 ≥ (1/10)x + 10

Answer:
Lm = 30
Step-by-step explanation:
QP/LM = PN/NL
(x - 1)/(x + 3) = 12/18
18(x - 1) = 12(x + 3)
18x - 18 = 12x + 36
18x - 12x = 36 + 18
2x = 54
x = 54 : 2
x = 27
LM = x + 3 = 27 + 3 = 30
