The scale 0.5 in : 6 ft, means that
any distance of 0.5 in on paper, represents 6 ft in reality
for example:
0.5*2= 1(in) represents 6*2=12 (ft)
0.5*4= 2(in) represents 6*4=24 (ft)
0.5*10=5(in) represents 6*10=60 (ft) and so on...
Let the wall be x (in) in the drawing:
0.5 (in) represents 6 (ft),
x (in) represents 30 (ft)
----------------------------------------
thus x = (0.5*30)/6 = 15/6= 2.5 (in)
Answer: 2.5 in
Answer:
Step-by-step explanation:
For Question 3, we are simply taking an input for the function, as a value of x and solving the equation. For part a, we substitute 3/14 into the first function, and solve it:
f(x) = 7(3/14) + 2
f(x) = 21/14 + 2
f(x) = 49/14
f(x) = 7/2
For part b, we take the input of -3 into the second function and solve the equation:
h(x) = 4(-3)^2
h(x) = 4(9)
h(x) = 36
For Question 4, we are simply solving this equation by isolating the x variable. First, we simplify the equation to 4-5x+15+2x = -2 and simplify this again to -3x+19 = -2. Now, we can subtract 19 from both sides of the equation to get -3x = -21. Lastly, we isolate the x variable by dividing both sides of this equation by -3, to get x = 7.
Y=-1/3x+2

-⅔ (6x + 9) = 18
Apply distributive property. Multipy -⅔ to 6x and 9.
-4x - 6 = 18
Add 6 to both sides so -4x can be alone.
-4x - 6 + 6 = 18 + 6
-4x = 24
To get x alone, divide both sides by -4.
-4/-4x = 24/-4
x = -6
x = -6 is your answer. I hope this helps! Let me know if you need more help or if I got something wrong.
