Answer:

I think answer is 3

Step-by-step explanation:

BD = DA

BE = EC

Now, BD/BE = DA/EC

or, x + 5/2x = 4/3

or, 3x + 15 = 8x

or, 15 = 8x - 3x

or, 15 = 5x

or, 15/5 = x

or, 3 = x

Therefore x = 3 Ans

Instructions: Simplify the algebraic expression. −12(32x−10y)

allochka39001 [22]

Answer:

-384x - 120y

Step-by-step explanation:

General Concepts and Formulas:

Brackets

Parentheses

Exponents

Multiplication

Division
Addition
Subtraction

Steps:

1) Distribute

$-12(32x-10y)$

We must distribute the expression above by multiplying -12 by the coefficients and then adding the variables.

So first, multiple -12 by 32 and add the variable 'x' when getting the product:

-12(-384x - 10y)

Now that we have one part, let's solve the other part.

We now must multiple -12 by -10, which gets us 120, now we must plug in:

(-384x - 120y)

(Remove parenthesis)

⇒ -384x - 120y

Which angles are linear pairs? Check all that apply.

AlexFokin [52]

Linear pairs are when 2 lines intersect, and are adjacent angles.

The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

I hope my answer helped!!!

What number goes on top and how do you solve it.

vekshin1

So basically, each number is equal to the two numbers below it added together.

See, 7 = 3+4, 8 = 5 +3, etc.

So, the top would be 16 + 17.

16 + 17 = 33

So 33 goes on top.
