Answer:x= -10

Step-by-step explanation

first add 4 to both sides of the equation which will cancel out the 4 and leave you with 2x= -20

then divide both sides by 2 to get the x by itself and divide -20 by 2 which will give you x= -10

A square has an area of 64 m². What is the length of each side?
anygoal [31]

Answer:

8m

Step-by-step explanation:

The area of a square is length*width.

We can square root the area to get the length of each side. Since the shape is a <em>square</em>, the lengths are the same.

\sqrt{64}=8

One side is <u>8m</u>.

convert the following logarithmic equation to the equivalent exponential equation. Use the caret (^) to enter exponents. y=ln x
GarryVolchara [31]
1. To solve this problem, you need to remember that an exponential function has the following form:
 
 f(x)=a^x
 
 "a" is the base and "x" is the exponent.
 
 2. It is important to know that the logarithmic functions  and the exponential functionsare inverse. Then, you have:
 
 <span>y=ln x
</span> e^y=e^(lnx)
<span> e^y=x
 
 3. Therefore, the answer is:
</span> 
 x=
<span>e^y</span>

Each student ticket for an art museum costs $12.50. the total cost for student tickets, t, varies directly as the number of tick
Troyanec [42]

An equation that models the proportional relationship between t and s.

t = 12.5s

<h3>What is proportional relationship?</h3>

Relationships between two variables where their ratios are equal are known as proportional relationships. The fact that one variable is always a constant value multiplied by the other in a proportionate connection is another way to conceive of them. This parameter is referred to as the "constant of proportionality."

<h3>According to the given information :</h3>

1) Ticket for an art museum costs $12.50

2) In other words, the price will increase by $12.50 for each ticket purchased (or tickets).

In other words, the total expense is always 12.5 times the quantity of tickets sold.

3) This indicates that we can create this ---> t = 12.5s.

An equation that models the proportional relationship between t and s.

t = 12.5s

The ratio of dogs to cats at an animal shelter is 33 to 22. How many dogs are at the shelter if there is a total of 3030 animals
Elena-2011 [213]
D : c = 33 : 22
where d is the number of dogs and c is the number of cats;
and: d + c = 3030
33 c = 22 d  / : 11
3 c = 2 d
From the other equation: c = 3030 - d
3 * ( 3030 - d ) = 2 d
9090 - 3 d = 2 d
5 d = 9090
d = 9090 : 5
d = 1818
Answer: There are 1818 dogs in the shelter.
