Add the   x^3:- 6 x3 + 3x3 = 9x3
              x's:- -8x + 6x = - 2x
               -5 + 2 = -3

the first choice is the correct one

A cat chases a mouse. The cat is originally 4 feet behind the mouse, which is running in the same direction along the same route
Verdich [7]

Step-by-step explanation:

The position of the mouse at time t is 4 + 12t.

The position of the cat at time t is 17t.

When the positions are equal:

4 + 12t = 17t

4 = 5t

t = 0.8

It takes 0.8 seconds.

Find the value of x.<br><br>• 5<br>• 20<br>• 40<br>• 45​
insens350 [35]

Answer:

3rd option: x= 40

Step-by-step explanation:

4x° +20°= 180° (adj. ∠s on a str. line)

<em>Bringing</em><em> </em><em>constants</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>:</em>

4x°= 180° -20°

<em>Simplify</em><em>:</em>

4x°= 160°

<em>Divide</em><em> </em><em>by</em><em> </em><em>4</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

x°= 40°

Thus, x=40.

Louann and Carla received equal scores on a test made up of multiple choice questions and an essay. Louann got 14 multiple choic
Gnoma [55]
Louann= 14x+24
Carla= 16x+14
 So basically this is just like solving equations. The way I did this was just put random numbers for x and then solve it.
First attempt: 
14(7)+24=16(7)+14
98+24=112+14
122=126
 Okay the first one didn't work so I use 6 for x. 
Second attempt: 
14(6)+24=16(6)+14
84+24=96+14
108=110

So 6 didn't work and you already should know that the answers should be between 1 and 5. 

So now I going to do 5 for x
Third attempt:
14(5)+24=16(5)+14
70+24=80=14
94=94
 
And so the answer is 5! :D The multiply choice questions were worth 5 points and Louann and Carla had 94 for their scores! I hope this help you out and clear for you! :D

In your home you can make and paint 17 small planters in 5 days or 12 large planters in five days. You received an order for 50
Radda [10]

Answer:

25

Step-by-step explanation:

so you can use proportions for this. Since 17 small planters can be made in 5 days you would put 5 Days under 17 SP (Sp = small planters) Then you would do 17 times x which equals 17x and 5 times 50 which equals 250. you would then divide them by each other . 250 divided by 17 is a bunch of numbers but to shorten it you can just put 14.705 or 15 if you round it.

17sp 50

----------------- 250/17 = x =14.705

5D x

you would then do the same to the other Large planters.

12LP 24. 120/12 = x = 10

-------------

5D. x

the question is how many days to make them ALL. so you would then add 10 + 14.705 which equals 24.705. then you can round that to 25 DAYS.
