Answer:
5/9
Step-by-step explanation:
Yes because one input (number of pounds of banana) will always have the same output (cost).
Answer:
True. This isn't really a question but it is a statement
Step-by-step explanation:
1 pound 80 cents
2 pounds 1.60
3 pounds 2.40
and so on
Use order of operations, or PEMDAS which stands for Parenthesis, Exponent, Division, Addition, and Subtraction.
Do those operations in that order. Can you try?
What will be the first thing you do here, according to PEMDAS?
The cost of 1 hot dog is $1.75 and the cost of 1 hamburger is $2.
Let x be the cost of one hot dog and y be the value of one hamburger. we will set up a system of linear equations to solve for x and y:
From the first statement, we recognize that:
7x + 2y = 16.25 ----(1)
From the second statement, we know that:
2x + 7y = 17.50 ----(2)
We will use both substitution or elimination method to solve this system of equations. let's use elimination method right here. we are able to multiply equation (1) through 7 and equation (2) by 2 to eliminate y:
49x + 14y = 113.75 ----(3)
4x + 14y = 35 ----(4)
Subtracting equation (4) from equation (3), we get:
45x = 78.75
Dividing each sides by using 45, we get:
x = 1.75
Substituting x = 1.75 into equation (1), we can solve for y:
7(1.75) + 2y = 16.25
12.25 + 2y = 16.25
2y = 4
y = 2
Consequently, the cost of 1 hot dog is $1.75 and the cost of 1 hamburger is $2.
