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

<u>Answer:</u>
Ordered pair = (3, 2)
<u>Step-by-step explanation:</u>
We are given the following equations and we are to solve them by substitution method:
--- (1)
--- (2)
Substituting the value of y from equation (2) to (1):
x = 3
Substituting this value of x in equation (2):
y = 2
So the ordered pair is (3, 2).
Answer:
M/6 = G/5
Step-by-step explanation:
We are given a relation between the numbers of students in two different groups. That relation can be used to write an equation.
<h3>Groups who bought M&Ms</h3>
If we consider M&M buyers to be 6 in a group, then the number of those groups is ...
M/6
<h3>Groups who bought gum</h3>
Similarly, the number of groups who bought gum will be ...
G/5
where there are 5 gum-buyers in each group.
<h3>Equation</h3>
The problem statement tells us that for each group of one kind, there is a matching group of the other kind. That is, the numbers of groups are equal:
M/6 = G/5
