$\sf \: 2x + 31 = 5$

$\sf \longmapsto \: 2x = 5 - 31$

$\sf \longmapsto \: 2x = -26$

$\sf \longmapsto{x }= \frac{ - 26}{2}$

$\sf \longmapsto \: x = - 13$

$\boxed{\sf - 13}$

2x + 31 = 5

2x = 5 - 31

2x = -26

x = -26/2

x = -13.

WILL MARK BRAINLIEST

Aneli [31]

Answer: 37 donuts

Step-by-step explanation:

coffee for 2,

donuts for 1.5

c = coffee

d = donuts

lets make an equation

c*2 + (80-c)*1.5 = 141.5

from this we get:

c= 43.

if c = 43, then d is 80-43 = 37.

they sold 43 coffees, and 37 donuts.

lets check the math

43*2+37*1.5 = 141.5. math checks out

The mass of a radioactive element at time x is given by the equation below, where c is the original mass and h is the half-life

krek1111 [17]

$\bf M(x)=c(0.5)^{\frac{x}{h}}\implies 10=36(0.5)^{\frac{x}{4.9}}\implies \cfrac{10}{36}=0.5^{\frac{x}{4.9}}
\\\\\\
\cfrac{5}{18}=0.5^{\frac{x}{4.9}}\implies log\left( \frac{5}{18} \right)=log\left( 0.5^{\frac{x}{4.9}} \right)
\\\\\\
log\left( \frac{5}{18} \right)={\frac{x}{4.9}}\cdot log\left( 0.5 \right)\implies 
\cfrac{4.9\cdot log\left( \frac{5}{18} \right)}{log(0.5)}=x$
