Answer:
39.9 grees
Step-by-step explanation:
Since 4.2 kribs = 18 grees
Then,
1 krib = 18/4.2 grees
9.3 kribs = (18/4.2) x 9 3
9.3 kribs = 39.9 grees.
Answer:
2.3
Step-by-step explanation:
The algebraic expression that represents the total cost would be: A. 1.25r.
<h3>How to Write an Algebraic Expression?</h3>
Given that the number of donuts Rick buys for his family is represented by letter "r", and we also know that:
cost of each donut = $1.25.
Using an algebraic expression, we can create a mathematical expression that shows the total cost for Rick to by a given number of donuts for his family.
Thus:
1 donut = 1.25
r donuts would cost: 1.25 × r = 1.25r.
Therefore, the algebraic expression that represents the total cost would be: A. 1.25r.

Answer:
A
Step-by-step explanation:
plug in y and x, if you want to be sure of each answer
In the case of A) here are the 2 equations, y-2=x+4 and 3x+4=x+6
now plug in what a describes
x=1, y=7
7-2=1+4 and 7=7
Therefore the answer is A
