Answer: X = (d-b) / (a-c)
This way this worded is weird but I think I got it
Step-by-step explanation:
Subtract B from both sides
ax = cx +d -b
Then subtract CX from both sides
ax -cx =d-b
Distributive Property
x(a-c) =d-b
Divide both sides by a-c
X = (d-b) / (a-c)
Answer:
120% = 120/100 = 1.2
Step-by-step explanation:
100 points = 100%, so 120 points = 120%
120% = 120/100 = 1.2
Answer:
380
Step-by-step explanation:
285 / x = 75 / 100
Cross multiply 28500 = 75x
Divide by 75 380
Answer:
65.8 ft
Step-by-step explanation:
The number of strings required to tie each vertex to the other three will be ...
(4)(3)/2 = 6
Those strings will be perimeter strings plus two diagonal strings. The lengths of the perimeter strings are given as 12 ft and 7 ft. The lengths of the diagonal strings can be found using the Pythagorean theorem.
d² = 12² +7² = 144 +49 = 193
d = √193 ≈ 13.892
Then the total length of all strings is ...
L = 2(12.0 +7.0 +13.9) = 65.8 . . . . feet
The artist will need 65.8 feet of string.
D. if something is directly proportional then if something happens to X the exact same thing needs to happen to Y
