Answer:

Step-by-step explanation:

178-10+3(25+1)2

We need to use order of operation (Pemdas).

P-Parenthesis

e-Exponents

m- Multiplication

d- Division

a- Addition

s-Subtract

178-10+3(25+1)2

178−10+3(25+1)(2)

=168+3(25+1)(2)

=168+(3)(26)(2)

=168+(78)(2)

=168+156

=324

The answer chooses give are not close to 324 but we need to pick a expression tat is equivalent.

Equivalent means equal in value.

None of these answer choose are equal to 324

Write the equation of the line that passes through the points (3, 6) and (5, 18) using function notation.

andreev551 [17]

Answer:

$f(x) = 6x -12$

Step-by-step explanation:

We must write the function of the line in the form $f (x) = mx + b$

First calculate the slope m

$m =\frac{y_2-y_1}{x_2-x_1}$

$y_2 = 18\\y_1 =6\\x_2=5\\x_1=3$

$m= \frac{18-6}{5-3} = 6$

Then

$f(x) = 6x +b$

To have b replaced a point in the function

$f(3)=6 = 6(3) +b\\\\6-18= b\\\\b=-12$

Finally the function is

$f(x) = 6x -12$

Sonja [21]

It’s easier to see with actual numbers therefore, since you are not given a total, say there are 20
Which means, 10 are peanuts, 5 are chocolate candies and 5 are dried fruit.
Out of the 20 options, there are 5 that are the chocolate candies.
This means there is a 5 in 20 chance you will pick the chocolate candies.
5/20 = ¼ (i.e. the likelihood to pick one is the same as the fraction of chocolate candies the bag contains)
