Step-by-step explanation:

According to pemdas, we would just add/subtract across. So we will complete these steps:

Step 1:

9+10-4+78

19-4+78

Step 2: 

19-4+78

15+78

Step 3:

15+78

In conclusion, the answer is 93.

Please help me out by marking this answer brainliest, and giving me a thanks!

Work out m and c for the line: 3 y + 6 x = − 3

Usimov [2.4K]

Answer:

m is -2 and c is -1

Step-by-step explanation:

• Let's first phrase out the general equation of a line

${ \rm{y = mx + c}}$

m is the slope
c is the y-intercept

[ remember that a general line equation must be in slope - intercept form as shown above ]

• from our question, we are given the equation;

${ \rm{3y + 6x = - 3}}$

• let's make y the subject in order to make the equation in slope - intercept format.

→ remember to apply "subject making knowledge"

${ \rm{3y = - 3 - 6x}} \\ \\ { \rm{3y = - 6x - 3}} \\ \\ { \rm{ \frac{3y}{3} = \frac{ - 6x}{3} - \frac{3}{3} }} \\ \\ { \boxed{ \rm{y = - 2x - 1}}}$

• The above boxed equation is now a general equation. Let's extract out slope, m and y-intercept, c

${ \rm{m \: \dashrightarrow \: - 2}} \\ \\ { \rm{c \: \dashrightarrow \: - 1}}$

Please andwer this for me <3

mina [271]

Answer:

Step-by-step explanation:

16 : 12

x : 6

- multiply 16*6 and divide by the number multiplying with the unknown (12)

(16*6)/12 = 8

- area of triangle is 1/2 h*b

so 1/2 * (16*8) = 64
