X/5 + x/2 =14
⇒ 2x/10 + 5x/10 = 14 (common denominator)
⇒ 7x /10 = 14
⇒ 7x* (10/10) = 14*10
⇒ 7x = 140
⇒ (7/7)*x= 140/7
⇒ x= 20
The final answer is x=20.
Hope this helps~
Answer:
one solution
Answer: The given equation 3x − 7 = 4 + 6 + 4x has one solution.J
Step-by-step explanation:
The answer is 10.
Parallel lines show similar triangles showing us that (2x + 6)/10 = (x+6)/8. Solving this equation for x gives us x = 2. Plugging this into 2x + 6 gives us 2(2) + 6 = 10.
The longer sides are 20 kilometers, and the shorter sides are 13 kilometers.
(Length times width equals 260, and 20 times 2 plus 13 times 2 is 66.)
Aren’t you supposed to multiply the exponents to where it’s 5^24 ?
