Answer:
It is a rational number
Step-by-step explanation:
A rational number is defined as numbers written in p/q form ,q not equal to 0,p&q are integers
-6 is same as -6/1
since -6,1 are integers it is a rational..
Answer:
2
Step-by-step explanation:
1/8 x 16=2
1/8 pound=2 ounces
1 pound= 16 ounces
Here, we need to construct 2 linear equation.
Let x be the plate and y be the cup.
1) 4x + 3y = 20.70
2) 5x + 4y = 26.40
From equation 1, we solve for y.
3y = 20.70 - 4x
y = (20.70 - 4x) / 3
Substitute into equation 2.
5x + 4((20.70 - 4x) / 3) = 26.40
5x + 27.60 - 5.33x = 26.40
-0.33x = 26.40 - 27.60
-0.33x = -1.2
x = 3.64
We already get value of x. Now, calculate for value of y.
y = (20.70 - 4x) / 3
y = (20.70 - 4(3.64)) / 3
y = 2.05
The cost for 1 plate is 3.64 dollars and 1 cup is 2.05 dollars.
