Answer: x= 10

Step-by-step explanation:

l= 40

w=20

P=l+w+l+w

120=5x-10+2x+5x-10+2x

120= 14x-20

120+20=14

140=14x

x=10

Answer:

x=10

L=40

W=20

Step-by-step explanation:

P=2L+2W

120=2(5x-10)+2(2x)

120=10x-20+4x

120=14x-20

14x=140

x=140/14=10

50 points!!!!! Please!!!!! Sandra and Jenny spend a certain amount of money from their money box each month to buy plants. The t
nekit [7.7K]

Answer:

A) Function 2 shows a greater rate of change because Jenny spends $6 each month and Sandra spends $5 each month.

Step-by-step explanation:

The y-intercept for Sandra is 55 and the slope is -5. While Jenny's y-intercept is 50 and slope is -6.

6 is a greater number therefore causing Jenny's slope to decrease faster causing her to have less money at a much faster rate. (rate of change=slope) Jeny's slope is decreasing at a faster rate of change because she is spending more money everyday than Sandra is.

Hope this helps! Have a great day! :)

What is the solution set of the equation X/5 + x/2 =14?
JulijaS [17]

Answer:

x= 20

Step-by-step explanation:

Solve for x:

(7 x)/10 = 14

Multiply both sides of (7 x)/10 = 14 by 10/7:

(10×7 x)/(7×10) = 10/7×14

10/7×7/10 = (10×7)/(7×10):

(10×7)/(7×10) x = 10/7×14

10/7×14 = (10×14)/7:

(10×7 x)/(7×10) = (10×14)/7

(10×7 x)/(7×10) = (7×10)/(7×10)×x = x:

x = (10×14)/7

14/7 = (7×2)/7 = 2:

x = 10×2

10×2 = 20:

Answer:  x = 20

Pani-rosa [81]

Answer:

tanA=34⟹sinA=332+42−−−−−−√=35  

Now, we have

sinAcosA=tanA  

⟹3/5cosA=tanA  

⟹cosA=13×54×3  

⟹cosA=45  

⟹cosAsinA=4×35×5=1225
