Answer:

Step-by-step explanation:

−23(3x−4)+3x=5619/6 Remove brackets on the left. Divide by 6 on the right.

-69x - 92 + 3x = 936.5 Combine like terms on the left.

-66x - 92 = 936.5 Add 92 to both sides

-66x = 936.5 + 92

-66x = 1028.5 Divide by -66

x = -15 7/12

Neko [114]

Answer:A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Write and solve an equation to find the length of each side of the triangle.

The sides can be found by taking the square root of the area. , where = side. . So the length of a side is 6.3 cm.

Ronch [10]

Answer:

793.25 mi/hr

Step-by-step explanation:

Given that:

The radius of the earth is = 3030 miles

The angular velocity = $\dfrac{\pi}{12} rads$

If a jet flies due west with the same angular velocity relative to the ground at the equinox;

We are to determine the How fast in miles per hour would the jet have to travel west at the 40th parallel for this to happen.

NOW;

Distance s is expressed by the relation

s = rθ

$s = 3030(\frac{\pi}{12} )$

s = 793.25

The speed which depicts how fast in miles per hour the jet would have traveled is :

$speed (v) = \frac{s}{t}$

$v = \frac{793.25}{1}$

v = 793.25 mi/hr

Hence, the jet would have traveled 793.25 mi/hr due west at the 40th parallel for this to happen.

Which of the following is the solution? A. 2 B. 5≤x<−2 C. 2≤x≤5 D. −5

WARRIOR [948]

Answer:

we conclude that:

$8\le \:-4x$

The graph is also attached below.

Step-by-step explanation:

Given the inequality expression

$9\le 1-4x$

simplify

$9\le -4x+1$

Add -1 to all parts

$9+(-1)\le -4x+1+(-1)$

simplify

$8\le -4x$

Divide all parts by -4

$\frac{8}{-4}\le -\frac{4x}{-4}$

$-2\ge \:x>-5$

Thus, we conclude that:

$8\le \:-4x$

The graph is also attached below.
