i think it's A not sure, but if it is wrong i'm very sorry. I'm pretty sure it's right.
this is not a rectangle, it's a square.
115.2 pounds of type A coffee were used.
<h3>What is the solution of the equation?</h3>
A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved.
Let the number of pounds of type A coffee be x and the number of pounds of Type B coffee be y.
According to the question, the equations are,
5.50x + 4.40y = 762.30
x = 4y
So, the solution of the equation is obtained as follows:
5.50(4y) + 4.40y = 762.30
26.40y = 762.30
y = 762.30/26.40
y = 28.8 pounds
x = 4*28.8 = 115.2 pounds

We are asked to get the algebraic expression of the given phrase "twelve times the sum of a number and seven-tenths". The solution is shown below:
Let start with the phrase "number and seven-tenths", We need to assign "x" to represent the unknown number such that the phrase equals to "x+ 7/10".
To complete the algebraic expression of the phrase "twelve times the sum of a number and seven-tenths", we have:
12(x+7/10)
The answer is 12(x + 7/10).
