Mary has 4 marbles because Joan has 100 marbles and he has 25 times as many marbles as Mary so we divide :)

Factor -3/4 out of 3/2x - 9/4y

Vikki [24]

Answer:

$-\frac{3}{4} \times (-2x +3y)$

Step-by-step explanation:

To factor out -3/4 out of that equation, multiply and divide by -3/4.

Say ;

= $\frac{3}{2}x -\frac{9}{4}y$

= $(\frac{3}{2}x -\frac{9}{4}y) \times \frac{-\frac{3}{4} }{-\frac{3}{4}}$

Now, rearranging and making necessary commutations.

= $-\frac{3}{4} \times (\frac{3}{2}x -\frac{9}{4}y) \times \frac{1 }{-\frac{3}{4}}$

= $-\frac{3}{4} \times (-2x +3y)$

Factoring -3/4 we get an equation without any fractions

= -2x + 3y

Find 10 rational number between 6/7 and -5/7 please give me right solution

erik [133]

Answer:

Step-by-step explanation:

Note that the distance from -5/7 to 6/7 is 6/7 - (-5/7) = 11/7.

So, if you take steps of 1/7 each, there are 10 steps between -5/7 = 11/7.

-4/7, -3/7, -2/7, ..., 5/7

Geometry: Similarity, Congruence, Proofs Question: Why are proofs so picky? Why can’t we just measure the two figures to see if

FrozenT [24]

Answer:

Haha proofs are an interesting thing. Usually, nothing is to scale, which is why you can't measure anything. They are pretty annoying, but it helps to know why certain things are the way that they are and develop justification skills for higher level math.

Sorry to discourage you, but you're going to see "Justify" quite a lot in calculus and beyond which is basically a more informal version of a proof

you can never escape it tbh lol
