Ivan had saved some quarters. He spent 50 quarters, which was 2/5 of the quarters he started with. How many quarters did he start out with?

Answers

Answer 1
Answer: since 50 was 2/5 of the total, 25 must be 1/5. multiply 25*5 to get the total of 125 quarters ($31.25 in case you were wondering)

The formula F = 1.8C + 32 allows you to find the Fahrenheit (F) temperature for a given Celsius (C) temperature. Solve the equation for C to produce a formula for finding the Celsius temperature for a given Fahrenheit temperature

Answers

Answer:

The formula to calculate the Celsius temperature for a given Fahrenheit temperature is:

C=(F-32)/(1.8)

Step-by-step explanation:

Given formula:

F=1.8C+32

where F represents temperature in Fahrenheit and C represents  temperature in Celsius.

To solve the equation for C.

Solution:

We have,

F=1.8C+32

Subtracting both sides by 32.

F-32=1.8C+32-32

F-32=1.8C

Dividing both side by 1.8

(F-32)/(1.8)=(1.8C)/(1.8)

(F-32)/(1.8)=C

∴ C=(F-32)/(1.8)

Using the above formula, we can calculate the Celsius temperature for a given Fahrenheit temperature.

Best Regards,

Wolfyy :)

Answer:

48.6 is the answer

Step-by-step explanation:

Okay, first you plug in the variables  x and y .

So now the new equation is 10.2x2 this is ,because everytime a number get put next to another number you multiply.  So .....

(10.2x2) + (9.4x3)=

20.4+28.2=
