3.9x + 1.4 = 17 what is the steps​

Mathematics
1 answer:
Vedmedyk [2.9K]3 years ago
6 0

Answer:

x=4

Step-by-step explanation:

3.9x + 1.4 = 17

Having a decimal is not very nice to deal with, so we multiply all sides by 10 to get rid of the decimals.

3.9x*10+1.4*10=17*10

39x+14=170

Subtract 14 from both sides:

39x+14-14=170-14

39x=156

Divide both sides by 39:

\frac{39x}{39}=\frac{156}{39}

x=4

A teenager’s heart pumps an average of 7200 L of blood every 24 hours. What is the rate of change of volume of blood?
love history [14]

Answer:

300L per hour

Step-by-step explanation:

The rate of change of volume of blood pumped by the teenager's heart expresses the volume of blood pumped with respect to hour.

Rate of change of volume of blood = \frac{volume of blood}{time}

                           = \frac{7200L}{24}

                           = 300L/hour

The rate of change of volume of blood by the teenager's heart is 300 litres per hour. This implies that his/ her heart pumps 300 litres of blood every hour.

If Sarah has 50 Nickles and 20 dimes and Bill has 230 pennies and 5 quarters. Who has the more amount of money?
ser-zykov [4K]

Hi,

Your Question states: If Sarah has 50 Nickles and 20 dimes and Bill has 230 pennies and 5 quarters. Who has the more amount of money?

Answer: Sarah

Explanation: Sarah amount is $2.50, because the amount of nickels is 5 cents and if you multiply 5 times 50 you answer becomes $2.50. 20 dimes and every dime is 10 multiples up to $2.00. 230 is $2.30, and 5 quarters each being 25 cents is $1.25 so your answer is Sarah with 50 nickels.

I Hope I Helped!
