Answer:
Total cost= $235
Step-by-step explanation:
Giving the following information:
Dontae wants to buy 100 tiles for his kitchen floor. The tiles cost $2.35.
<u>To calculate the total cost, we need to use the following formula:</u>
Total cost= 2.35*x
x= number of tiles
<u>For 100 tiles:</u>
Total cost= 2.35*100
Total cost= $235
Answer: 4 = n
Step-by-step explanation:
5n + 34 = -2(1-7n)
Distribute negative 2 to both 1 and negative 7n. You do this first due to the rules of PEMDAS
5n + 34 = -2 + 14n
Add two to both sides of the equation in order to further isolate (n) in 14.
5n + 36 = 14n
Subtract 5n from both sides of the equation so that the values with (n) are on one side of the equation.
36 = 9n
Divide nine from 36 and 9n in order to isolate (n).
4 = n
This then gives you your final answer.
Answer:
No solution
Explanation:
When simplified, the statement 7=17 is formed. That statement is false, so there is no solution to this equation.
Answer:
(-7, 14)
Step-by-step explanation:
The function f(x) is equal to the y-coordinate. The value inside of the parenthesis is the x-coordinate, so it would be -7 in this problem.
