Please Solve Step By Step. 3x * 10 - (9-0) * 5

2 answers:

8 0

First you need to distribute that invisible -1 to (9-0). You do this because of PEMDAS. -9+0 will be your outcome first. You can disregard the zero and now multiply 10 * -9 * 5 as these have no x variable. Multiplying all of those you get -450 * 3x. Thats the simplified form of this problem. -1350x if you're teachers looking for that.

This is an order of operations question so you would do the parenthesis first which would be 9-0 then multiplication would be either *5 or 3x*10 and the answer is -15x

Answer:

The other coordinate is (-6,19)

Step-by-step explanation:

$m = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

(4,-7)

(x,y)

[(4+x)/2 , (-7+y)/2] = (-1,6)

(4 + x)/2 = -1

4 + x = -2

× = -6

(-7 + y)/2 = 6

-7 + y = 12

y = 19

Answer:

a) x > − 24 $\frac{3}{4}$

b) x < − 3

c) q < 56

Step-by-step explanation:

a) −2/5x−9<9/10

<=> 2/5x + 9 > − 9/10

<=> 2/5x > − 9/10 − 9

<=> 2×2/2×5x > − 9/10 − 9×10/10

<=> 4/10x > − 99/10

<=> x > − 99/4

<=> x > − 24 $\frac{3}{4}$

b) 4x+6<−6

<=> 4x < − 6 − 6

<=> 4x < − 12

<=> x < − 12/4

<=> x < − 3

c) q+12−2(q−22)>0

<=> q+12−2q −2×(−22)>0

<=> (q−2q) + (12+ 44) >0

<=> −q + 56 >0

<=> q < 56
