Answer:

Step-by-step explanation:

(8/3) / (-4/9)

when dividing fractions you use the acronym k.c.f (keep change flip)

keep the first fraction

change the operation (divide to multiply)

flip the other fraction

(8/-3) x (9/4)

after re-writing your expression, you want to solve

do this by multiplying both numerators by each other and same with the denominators

(-8x9) / (3x-4)

then you get a new fraction,

-72/-12

simplify,

-72/-12 = 6 (multiplying/dividing 2 negatives will always give you a positive)

What is the first step when solving the following inequality x+2/-5<4? Group of answer choices A. Add 5 to both sides and DO

LiRa [457]

Assuming we're dealing with $\frac{x+2}{-5} < 4$ , which is the same as writing (x+2)/(-5) < 4, then the answer is choice C.

We multiply both sides by -5 and this will flip the inequality sign.

-------------------------------------

Multiplying or dividing both sides by a negative number flips the inequality sign.

An example would be saying -2x < 10 leads to x > -5

What we can do is divide both sides by -2 and flip the inequality sign, or we could follow the steps shown below

-2x < 10
0 < 10+2x ... adding 2x to both sides
-10 < 2x ... subtracting 10 from both sides; this is one way to see why the sign flip happens
2x > -10
x > -10/2 ..... dividing both sides by 2
x > -5

In exercises 1 and 2, Find the value of x.

Kruka [31]

From the given picture, we can see that 2 sides are congruen, then the given triangle is an isosceles triangle. In this triangle the base angles are congruent, so we can draw the following picture:

Now, since interior angles of any triangle add up to 180 degrees, we have
