Simplify the expression. 3 + 2 • (–8) A. –40 B. 40 C. 13 D. –13 Please help me

Answers

Answer 1

Answer: We need to follow PEMDAS.

We need to do the multiplication before we can do the addition (which becomes subtraction because of the sign).

3 + 2 • (–8)

3 + (-16)

3 - 16

-13

Your answer is D. -13

Answer 2

Answer:

$\huge\text{Hey there!}$

$\huge\textbf{Equation:}$

$\mathbf{3 + 2 * (-8)}$

$\huge\textbf{Simplifying it:}$

$\mathbf{3 + 2 * (-8)}$

$\mathbf{\mathbf{\rightarrow3 + 2(-8)}}$

$\mathbf{\rightarrow 3 + (-16)}$

$\mathbf{\rightarrow 3 - 16}$

$\mathbf{\rightarrrow -13}$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{\frak{Option\ D. -13}}\huge\checkmark\n$

The answer is 5.4. Anything from 0-4, you drop. If you have a number from 5-9, you take off that number and add 1 to the next number. (The number to the left is what you add one to.) I hope I have helped you.

WILL MARK BRAINLIEST!The multipliers of this system of equations have been determined to create opposite terms of the y-variable.

4 (one-fourth x minus three-fourths y = 34) right-arrow x minus 3 y = 136
24 (three-fourths x + one-eighth y = negative 12) right-arrow 18 x + 3 y = negative 288

Answers

Answer:

thus, x=-34 and y=170/-3

Step-by-step explanation:

4((1/4)*x-(3/4)*y)=34

x-3y=136

24((3/4)*x+(1/8)*y)=12

18x+3y=-288

4x-3y=34⇒x-3y=136

18x+3y=12⇒18x+3y=-288

lets solve 4x-3y=34⇒x-3y=136 first:

4x-3y=34

x-3y=136

4x-3y=34

-x+3y=-136

3x=-102

x=-102/3

x=-34

lets plug in x to one of the equations, since both equations are equal to each other:

4x-3y=34

4(-34)-3y=34

-136-3y=34

-3y=170

y=170/-3

now lets solve: 18x+3y=12⇒18x+3y=-288

18x+3y=12

18x+3y=-288

18x+3y=12

-18x-3y=288

0 $\neq$ 300

so, this system doesn't work

thus, x=-34 and y=170/-3

aisha used six boards on each of the birdhouses she made .which experssion represents the total number of boards she would need to make n birdhouse

Answers

Well normally you would have to know the amount of birdhouses that she made. But if not, then it would be multiplying 6 times the number of n the amount of birdhouses that she made. Not sure if this is making sense. but if there are 6 boards for N (each of the bird houses) then the answer would just be 6n which is 6 times n
