Step-by-step explanation: We can write a ratio using the word "to", using a colon, or using a fraction bar.

Here, since we want our ratio in simplest form,

I would use a fraction bar.

Now, the problem asks us to compare

the number of boys to the number of girls.

We know that there are 12 boys

and we know that there are 15 girls.

So our ratio is 12/15.

However, this can be reduced to 4/5.

Evaluate 3x+4(y+3) when x is 5 less than the quotient of y and 3, and y=18.

romanna [79]

It is given that x is 5 less than the quotient of y and 3.

And given value of y is 18 .

So quotient of y and 3 is

$\frac{18}{3} = 6$

And 5 less than 6 =1

So we have y=18 and x=1

Given expression is

$3x+4(y+3)$

At x=1 and y=18, we will get

$3(1)+4(18+3) =3 + 4(21)$

$= 3+84=87$

Solve the system of equations by graphing. Look at the picture. Will Mark Brainliest

Answer:

See below

Step-by-step explanation:

<h3>Graphing:</h3>

we are given two functions

$\displaystyle \begin{cases}f(x) = - x + 5 \\ g(x) = {x}^{2} - 3x + 2\end{cases}$

where f(x) is a linear function and g(x) is a quadratic function

we want to figure out the solutions of the function

let's graph f(x):

the Black-table is attached

let's graph g(x):

the picture is attached

hence, the graph should be

the graph is attached

<h3>solutions stating:</h3>

so we need solution(s) which satisfy(ies) the both functions

in this case the solution (s) the x coordinate(s) where both functions intercept we get from the graph that both functions intercept at (-1,6) and (3,2)

hence,

x={-1,3}

How many ounces of a silver alloy that cost $4 an ounce must be mixed with 10oz of an alloy that costs $6 an ounce to make a mix

scoray [572]

Answer:

x = 52.5

Step-by-step explanation:

4x + 6(10) = 4.32(x + 10)

4x + 60 = 4.32x + 43.20

0.32x = 16.8

x= 52.5

Can somebody please help me with this pleaseee

Semmy [17]

Answer: -2, 2

Step-by-step explanation:

0 = 5x^2 -20

0 = 5(x^2 -4)

0 = 5(x - 2)(x + 2)

0 = x - 2

2 = x

0 = x + 2

-2 = x
