I assume what you mean by this question is an equation like this:

1 + 2 x 3 + 4
Or,
3 x 4 + 6 /div 5

What you'd do:
1+2 x 3+4 First, add either 1+2 or 3+4 which is 3 & 7. then, youd multiply your answers as, 3 x 7 which is, 21.

Rom4ik [11]

Answer: 91

Step-by-step explanation:

Let adults tickets be a

Let students ticket be b.

The information in the question can be presented as an equation as:

a + b = 218 .......... i

8a + 5b = 1363 ......... ii

Multiply equation i by 5

Multiply equation ii by 1

5a + 5b = 1090 ........ iii

8a + 5b = 1363 ....... iv

Subtract iii from iv

3a= 273

a = 273/3

a = 91

Number of adult's ticket sold = 91

The graphs below have the same shape.what is the equation of the red graph?

Setler [38]

Answer:

$G(x)=4-x^{4}$

Step-by-step explanation:

Notice that the red graph is the blue graph shifted 1 units up.

According to the function transformation rules, we add $k$ to the output of the function to shift its graph $k$ units up, and we subtract $k$ to the output of the function to shift its graph $k$ units down.

The output of our function is $3-x^{4}$ , and since we want to shift 1 units up, $k=1$ . In other words, we just need to add 1 to the output of the function:
