I need help ASAP like I might actually fail

2x + 7 ≤ 3x - 5

Start by keeping the variable x on the left side of the inequality, and move everything else to the right side.

We can do this by subtracting 3x from both sides and subtracting 7 from both sides.

-x ≤ -12

Divide both sides by -1 to make x a positive; when dividing by a negative number you will flip the inequality sign, so ≤ becomes ≥.

x ≥ 12

Possible solutions for x are any number equal to or greater than 12.

What is the value of x if the quadrilateral is a rhombus? please help

stiks02 [169]

In a rhombus, all sides are equal:

5x = 15
and x = 15/5 = 3

(you could have done the same thing with the other side: 5x = 4x +3)

PLEASE HEP ME QUICK!!!!: Tom travels between the two mile markers shown and then finds his average speed in miles per hour. Sele

slega [8]

Answer:

$speed=\frac{195\ miles}{3\ hours}$

$3\ hours=\frac{195\ miles}{speed}$

$3\ hours*(speed)=195\ miles$

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x -----> the distance in miles

y ----> the time in hours

$speed=\frac{x}{y}$

we have

The distance is equal to subtract 35 miles from 230 miles

$x=230-35=195\ miles$

The time is equal to subtract 1:30 pm from 4:30 pm

$y=4:30\ pm-1:30\ pm=3\ hours$

substitute in the formula of speed

$speed=\frac{195\ miles}{3\ hours}$

<em>Isolate 3 hours</em>

$3\ hours=\frac{195\ miles}{speed}$

<em>Isolate 195 miles</em>

$195\ miles=3\ hours*(speed)$
