Answer:

7 ft

Step-by-step explanation:

Perimeter of a rectangle is denoted by the formula: P=2l+2w , where l is the length and w is the width.

We know that P = 20 and that w = 3. So, let's plug these values in:

20 = 2l+2*3=2l+6

Isolate the variable l by subtracting 6 from both sides and dividing by 2:

2l=20-6=14

l=7

Thus, the answer is 7 feet.

Hope this helps!

Answer:

7 feet

Step-by-step explanation:

Perimeter = 2(length + width)

20 = 2(length + 3)

length + 3 = 10

length = 7 feet

Solve triangle ABC, when A= 6, B=10 and c=12
valentinak56 [21]
Use cosine rule,

cos(A)=(b^2+c^2-a^2)/(2bc)
=(10^2+12^2-6^2)/(2*10*12)
=13/15
A=29.926 degrees.................................(A)

cos(B)=(c^2+a^2-b^2)/(2ca)
=(12^2+6^2-10^2)/(2*12*6)
=5/9
B=56.251 degrees.................................(B)

cos(C)=(a^2+b^2-c^2)/(2ab)
=(6^2+10^2-12^2)/(2*6*10)
=-1/15
C=93.823 degrees.................................(C)

Check:29.926+56.251+93.823=180.0 degrees....ok

Answer:

Step-by-step explanation:

-10 ( y-4) + 3y = 5   <--- substitute the value of x into first equation

-10y + 40 + 3y = 5

-7y + 40 = 5

-7y = -35

y= 5

x = 5 - 4

x = 1

Step-by-step explanation:

1.

  • (48 - 12.80)/2 = $17.6

2.

  • 250/6 ≈ 42 and more

3.

  • 485 - 319 = 166 more people

4.

  • 14.5x + 80 > 500
  • 14.5x > 420
  • x > 420/14.5
  • x > 29

5.

  • 1.25x + 3 ≤ 28
  • 1.25x ≤ 25
  • x ≤ 25/1.25
  • x ≤ 20 miles

6.  <em>This seems a typo... 460 is likely $60</em>

  • 60x + 145 ≤ 625
  • 60x ≤ 625 - 145
  • 60x ≤ 480
  • x ≤ 480/60
  • x ≤ 8 days
