Answer:
B
Step-by-step explanation:
He's typing 40 words per minute.
110 words divided by 2.75 minutes.
40 x 4.25 minutes= 170
3x+4y = 375
6x+ 4y= 600
-------------------
6x-3x = 600 - 375
3x=225
x=225:3
x=75 cents
3*x+4y= 375
3*75+4y=375
225 +4y = 375
4y=375-225
4y=150
y=150:4
y=37,5 cents
the price is 75+37,5=112,5 cents for one bag of potato chips and one candy bar
Answer:
1/5
Step-by-step explanation:
= 25 so x = -2 because

if x = -2 then plug in: 5^1/2(-2) = 5^-1 = 1/5
16= 6 ones or 16 ones
817= 8 hundreds and 7 ones or 17 ones
Hope this helps! :D
