Explanation
to solve this we need to translate into math terms, so
Step 1
a) let d represents the number of dimes
let n represents the number of nickles
so
re write the expressions

The number of nickels is three more than seven times the number of dimes in other words you have to add 7 to seven times the number of dimes to obtain the number of nickles
hence

therefore , the expression for the number of nickles is

I hope this helps you
Answer:
The correct options are:
x= -1.1
x= 2.4
x = 6
Step-by-step explanation:
The roots of any polynomial can easily be determined by the graph. To find the roots from the graph, we just have to see the values of x, for which the value of whole polynomial becomes 0.
We can see in the graph that there are three points where the value of polynomial becomes 0. that are
At x= -1.1
At x= 2.4
At x = 6
Thus, these are the roots
Answer:
x=215.63 ft
Step-by-step explanation:
sin(53)=x/270
x=270sin(53)
x=215.63 ft
Answer:
38 miles
Step-by-step explanation:
if it takes her one hour going at 10 mph to get to the train, she traveled 10 miles
if she took one hour on a train going 28 mph, then she traveled 28 miles
28+10 is 38
