Answer:
x=3
Step-by-step explanation:
1st distribute
8x-6-8=4+2x
2nd add
8x-14=4+2x
3rd move like terms
8x-2x=4+14
4th add the numbers
6x=18
5th divide both sides by 6
6x/6=18/6
x=3
Answer:
about 14 hours
Step-by-step explanation:
1 hour = 60 mins
845 divided by 60 mins
equals to 14.83 repeated
it would take 14 hours to drive 845 miles
Answer:
295.89%
Step-by-step explanation:
Let us assume the APR of the payday loan is r%.
Therefore, a $100 loan for the period of 1 year will charge $r.
So, $1095 loan for the period of 1 year will charge $
So, $ 1095 loan for the period of 1 months will charge $
Hence, $ 1095 loan for the period of 15 days will charge $
So,
⇒ 0.45625r = 135
⇒ r = 295.89
Therefore, the APR is 295.89%.
Cost of one pretzel is $2.5 and cost of one ice cream is $4.5
Step-by-step explanation:
Let,
Cost of pretzel = x
Cost of ice cream = y
According to given statement;
the cost of a pretzel is $2 less than the cost of some ice cream.
x = y - 2 Eqn 1
five ice creams cost the same as nine pretzels.
9x = 5y Eqn 2
Putting value of x from Eqn 1 in Eqn 2
Dividing both sides by 4
Putting y=4.5 in Eqn 1
Cost of one pretzel is $2.5 and cost of one ice cream is $4.5
