1. n-3^2
2. 7-(2/n)
3. n=35+(1/2*35)+14
4. (1/n^2)-(19*n)
Answer:
Circumfrence is pi*diameter. Radius is half the diameter, so..
23*2=46
And 46*pi
= 46pi
Slope= 1/2
Y intercept= (0,2)
Explanation:
Slope-intercept form is y=mx+b
-2x+4y=8
-8-2x=-4y
Divide by -4
2+1/2x=y
Y=1/2x+2
Answer:
d = 1.2e
30 dollars
Step-by-step explanation:
To write an expression, define the variables. E will be the number of euros and d will be dollars.
"Euro was equal to about 1.2 American dollars" is one euro equals 1.2 and two euros equals 2.4. So the expression is d = 1.2e.
This means if I have 1 euro, I have 1.2*1 = 1.2 dollars. If I have 2 euros, I have 1.2*2 = 2.4 dollars.
If I have 25 euros then d = 1.2*25 = 30 dollars.
Answer: 44 dollars
Step-by-step explanation:
so there is two ways to do this so ill show you both and you can see which one is easier for you!
method 1- divide the total amount of tickets by the amount with the cost. Then multiply that number by the cost
20/5=4 4*11=44
method 2- divide the money by the number with the cost. Then multiply it by the total amount of tickets.
11/5=2.2 2.2*20=44
