Jack and Julio each improved their yards by planting daylilies and geraniums. They bought their supplies from the same store.

o-na [289]

Cost of one daylily is $2 and cost of one geranium is $4.

Step-by-step explanation:

Let,

Cost of one daylily = x

Cost of one geranium = y

According to given statement;

x+5y=22 Eqn 1

13x+y=30 Eqn 2

From Eqn 1;

x=22 - 5y

Putting this value of x in Eqn 2;

$13(22-5y)+y=30\\286-65y+y=30\\-64y=30-286\\-64y=-256$

Dividing both sides by -64

$\frac{-64y}{-64}=\frac{-256}{-64}\\y=4$

Putting y=4 in Eqn 1

$x+5(4)=22\\x+20=22\\x=22-20\\x=2$

Cost of one daylily is $2 and cost of one geranium is $4.

How do you solve logarithmic equations such as log(2x)= -1 or 3log(2)+log(x)= 3?

Aliun [14]

Remember some simle log rules
loga+logb=log(ab)
xloga=loga^x
$log_ax=y$ means $a^y=x$
also, if no base is stated, assume base 10

so

log(2x)=-1 is base 10 and translates to
10^-1=2x
1/10=2x
divide both sides by 2 aka times 1/2
1/20=x

3log(2)+log(x)=3
log(2^3)+log(x)=3
log(8)+log(x)=3
log(8x)=3
base 10
10^3=8x
1000=8x
divide both sides by 8
x=125
