Write the following as a ratio: $72 for 488 photos

weeeeeb [17]

Answer:

The required ratio is 9 : 61

Step-by-step explanation:

Given,

$72 for 488 photos,

That is, the price of 488 photos = 72 dollars,

So, the ratio of price of photos and number of photos = $\frac{72}{488}$

∵ HCF(72, 488) = 8,

Thus, the ratio of price of photos and number of photos = $\frac{72\div 8}{488\div 8}$

= $\frac{9}{61}$

Solve Systems of Equations Algebracallyy=x+2 y=-3x

Sphinxa [80]

y = x + 2

y = -3x

Do y = -3x in y = x + 2

y = x + 2

-3x = x + 2

-3x - x = 2

-4x = 2

x = -2/4

x = -1/2

Now put x = -1/2 in y = -3x

y = -3x

y = -3.(-1/2)

y = 3/2

What is the solution to the following system of equations? x+y=5

marta [7]

Answer:

(3,2)

Step-by-step explanation:

Let's solve this via elimination method:

$\begin{cases} x+y=5\\x-y=1\end{cases}$

By subtracting equation 2 from equation one we obtain:

$\begin{cases} x+y=5\\-(x-y=1)\end{cases}\\\\0x+2y=4\\\\y=2$

Next we can use any equation either 1 or 2 to determine what x is, I'll use equation 1. Let y=2 and so:

$x+y=5\\\\x+2=5\\x=5-2\\\\x=3$

Therefore the solution for the system of equations is:

x=3 and y = 2 as an ordered pair we have (3,2)

Which is the last operation performed when evaluating (8 minus 2 x) squared + 4 for x = 3?

kompoz [17]

Answer:

addition

Step-by-step explanation:

The given expression is $(8-2x)^2+4$

We want to determine the last operation performed when evaluating this expression for x=3.

We substitute to get:

$(8-2*3)^2+4$

Multiply within the parenthesis to get:

$(8-6)^2+4$

Subtract to get:

$2^2+4$

Evaluate the exponent to get:

4+4

Add to obtain:

Hence the final operation is addition
