Answer:
<em>It has infinitely as many solutions</em>
Step-by-step explanation:
Equations and Identities
When dealing with equations, we must find values of the variable who mak the expression become an identity.
The expression is an identity regardless on what the value of x is, so we can say the equation has infinite as many solutions. For example x=0 will make the expression look like 3=3 which is an identity. If x=8, we'll obtain 27=27 and so on
35.75
explanation-
3.90 ph x 7.5 hours = 29. 25
plus the gas can 6.50
29.25+6.50= 35.75
The total amount is $ 1015.82 and interest amount is $ 165.82
<em><u>Solution:</u></em>
<em><u>The formula for amount when interest is compounded annually is:</u></em>

Where,
"A" is the total amount
"P" is the principal
"r" is the rate of interest in decimal form
"n" is the number of years
<em><u>From given, $850 at 2% for 9 years, compounded annually</u></em>
P = 850
t = 9 years

<em><u>Substituting the given values we get,</u></em>

Thus total amount is $ 1015.82
Interest amount = Total amount - principal
Interest amount = 1015.82 - 850
Interest amount = 165.82
Thus total amount earned is $ 1015.82 and interest amount is $ 165.82
Answer:
1. 45 minutes a day cycling
2.$1.55 on each cup of coffee a day
Step-by-step explanation:
1. You would figure up how much he jogs per week by multiplying 15 times 5 which would be 75 minutes and then from there you would subtract 75 from 300 and get 225 and divide 225 and 5 and end up with 45
2. You would multiply $.75 by 4 to figure up how much he spends on donuts which is $3 and then subtract 15.40 from 3 and get 12.40 and divide 12.40 by 8 since he goes twice a day and end up with 1.55
