A + R + J = 1925
A = 1/2R
J = 2R
1/2R + R + 2R = 1925
7/2R = 1925
R = 550
J = 2(550)
J = 1100
Joel collects 1100 cans.
Answer:
x=4.63
Step-by-step explanation:
Area = (1/2) (base) (height)
20 = (1/2) (x+4) (x)
40 = x²+4x
x²+4x-40=0
Put in quadratic equation:
x=
x=
x=4.63324958071 or x=-8.63324958071
Since x can't be negative in this case we take our answer to be 4.63324958071, which rounds to 4.63
Answer:
option (A) 62 miles
Step-by-step explanation:
Data provided in the question:
Ratio on the left = 434 miles : 14 gallons
ratio on the right = ?? : 2 gallons
Now,
The ratio on the both sides are equal
let the unknown value in the ratio be 'x'
Now, the ratio a : b can also be represented as 
therefore,
434 miles : 14 gallons = x : 2 gallons
or
⇒
=
or
⇒ x =
or
⇒ x = 62 miles
Hence,
the correct answer is option (A) 62 miles
Answer:
x = 50
Step-by-step explanation:
x/5 = 125/10
x * 10 = 125*4(cross multiply)
10x = 500 ( divide both sides by 10)
x= 50
