Which of the following is not a way to represent the solution of the inequality 7 - 9x - (x + 12) less than or greater to 25?

1 answer:

8 0

<span>To answer the question above first we need toclarify what the inequality is actually saying:

7 - 9x - (x + 12) </= 25 (simplify)

-5 - 10x </= 25 (add 5 to both sides)

-10x </= 30 (divide by -10 to get x)

x >/= -3 (don't forget to flip the signs when you divide by a negative number)

So this says x is greater than or equal to -3, so which of these statements is not a way to represent that?

I'd say it's the second one. x is greater than not less than.</span>

Which is traveling faster, a car whose velocity vector is 201 + 25), or a car whose velocity vector is 30i, assuming that the un

Snowcat [4.5K]

Answer:

2nd car is running faster than the first car by 2.01 units.

Step-by-step explanation:

Let's assume that

the velocity of first car,

$v_1\ =\ 20i\ +\ 25j$

and the velocity of second car

$v_2\ =\ 30i$

=> speed of first car,

$u_1\ =\ \sqrt{(20)^2+(25)^2}$

$=\ \sqrt{400+625}$

$=\ \sqrt{1025}$

= 32.01 units

and speed of second car,

$u_2\ =\ \sqrt{(30)^2+(0)^2}$

= 30 units

$u_2\ -\ u_1\ =\ 32.01\ -30$

= 2.01 units

Hence, 2nd car is running faster than the first car by 2.01 units.

What is 1 7/8 Times 2 1\3

slamgirl [31]

We need to convert the mixed fractions into improper fractions.

1*8 = 8
8+7 = 15

15/8

2*3 = 6
6+1 = 7

7/3

Now we can finish and multiply

$\frac{15*7}{8*3}$

15*7 = 105
8*3 = 24

Simplify 105/24

105/24

24*4 = 96

105 - 96 = 9

4 is the whole number, and 9 is the numerator.

4 9/24

Simplify that,

9/3 = 3
24/3 = 8

4 3/8

Answer: $4\frac{3}{8}$
