Whould anyone mind helping please. The first box says 6.25x+12x=30.75 the second box says 6.25x+12=30.75 3rd box says 6.25x+30.7
Snowcat [4.5K]

Answer:

The correct equation is: 6x+12 = 30.75

And 3 people went to the movies

Step-by-step explanation:

We will write the equation to represent this scenario.

Let x be the number of people who went for movies.

Then the price of ticket for x people will be: 6.25x

They spent $12 on refreshments and a total of $30.75 so the equation will be:

6.25x+12=30.75

solving the equation will give us total number of people

So,

6.25x+12 = 30.75\\6.25x = 30.75-12\\6.25x = 18.75\\\frac{6.25x}{6.25} =\frac{18.75}{6.25}\\x = 3

Hence,

The correct equation is: 6x+12 = 30.75

And 3 people went to the movies

Select all of the potential solution(s) of the equation 2log5x = log54.
Vanyuwa [196]

Answer:

x = ±2

Step-by-step explanation:

A equation is given to us , which is ,

\longrightarrow 2log_5(x) = log_5 4

From <u>properties </u><u>of </u><u>logarithm </u>we know that ,

\longrightarrow alog\ m = log \ m^a

Applying this to LHS , we have ;

\longrightarrow log_5 x^2 = log_5 4

Now the bases of logarithm on LHS and RHS is same . On comparing , we have ;

\longrightarrow x^2 = 4

Put square root on both sides,

\longrightarrow x =\sqrt{4}

Simplify ,

\longrightarrow \underline{\underline{ x =\pm 2 }}

This is the required answer.

What is the area of the triangle?<br> 9 4 12
LUCKY_DIMON [66]

Answer:

  13.636

Step-by-step explanation:

The area can be found using Heron's formula:

  A = √(s(s-a)(s-b)(s-c))

where s=(a+b+c)/2.

For the given triangle, ...

  a=9, b=4, c=12, s=(9+4+12)/2 = 12.5

  A = √(12.5(3.5)(8.5)(0.5)) = √185.9375 ≈ 13.636

The area of the triangle is about 13.636 square units.
