Answer:

8 and 9.

Step-by-step explanation:

Let the two unknown numbers be a and b.

When added together, they equal 17. In other words:

a + b = 17.

The difference between five times the first number and three times the second number is 13. In other words:

5a - 3b = 13.

We have a system of equations. We can use substitution. From the first equation, we can derive a = 17 - b. Let's substitute this in:

5(17 - b) - 3b = 13

85 - 5b - 3b = 13

-8b = -72

b = 9

a = 17 - b.

a = 17 - 9 = 8.

Thus, the two numbers are 8 and 9.

Answer:

The answer is $x=3$ .

Step-by-step explanation:

Given:

$\frac{x-3}{14}=0$

Multiply by 14 on both the side, it gives

$\frac{x-3}{14}\times 14=0\times 14\\ x-3=0$ .

Now we add 3 on both sides.

$x-3+3=0+3\\x=3$

Therefore, the answer is $x=3$ .

Certain clouds form when temperatures fall below -62c. What is the temperature in degrees Fahrenheit? Temperature is_ Greece Fah

Vadim26 [7]

Solution: The value of temperature is -79.6 degree fahrenheit.

Explanation:

The temperature is given in degree celsius and we have find the temperature in degree fahrenheit. The formula to convert the degree celcius in degree fahrenheit is given below,

$F=32+\frac{9}{5} C$

Where, F is temperature in degree fahrenheit and C is temperature in degree celsius.

Since it is given that the temperature is -62 degree celsius. So put $c=-62$ in the above formula.

$F=32+\frac{9}{5} (-62)$

$F=32+\frac{(-558)}{5}\\F=32-111.6\\F=79.6$

Hence the value of temperature is -79.6 degree fahrenheit.
