Covert 25 degree Fahrenheit to degree Celsius

Katarina [22]

Step-by-step explanation:

$f = \frac{9c}{5} + 32$

$25 = \frac{9c}{5} + 32$

$25 - 32 = \frac{9c}{5}$

$- 7 = \frac{9c}{5}$

$9c = - 7 \times 5$

$9c = - 35$

$c = \frac{ - 35}{9}$

$c = 3.88 {C}^{0}$

Sari has 3 times as many pencil erasers as Sam. Together, they have 28 erasers. How many erasers does Sari have?

BartSMP [9]

Let

x--------> amount of erasers that Sari has

y--------> amount of erasers that Sam has

we know that

$x=3y$ -------> equation $1$

$x+y=28$ -----> equation $2$

Substitute equation $1$ in equation $2$

$[3y]+y=28\\ 4y=28\\ y=28/4\\ y=7$

find the value of x

$x=3y\\ x=3*7\\ x=21$

therefore

the answer is

Sari has $21$ erasers
