Step-by-step explanation:
By simple interest formula:

A rational number is any number that can be expressed as the quotient or fraction
Answer:
Use the associative property to move the parentheses, and the expression becomes (d + 8d) + 1 + 7. Combine like terms, and the expression becomes 9d +8. Use the commutative property to change the order of the terms, and the expression becomes 8 + 9d.
Step-by-step explanation:
1 pizza for 4 students so 18 divided by 4 is 4.5 so 5 pizzas and there will be 1/2 a pizza left
You can isolate y and you know that the slope is the number in front of x (the one that multiplies it)
You know that the y-intercept is the value of y when x=0, therefore you can find y by replacing x with 0 in the equation
1-equation
5x-8y=3
5x=3+8y
5x-3=8y
(5x-3)/8=y
y=(5/8)x -3/8
(Slope = 5/8)
2- y-intecept (x=0)
y=(5/8)(0)-3/8
y=-3/8
