Answer:
Step-by-step explanation:
Through prime factorization,
Answer: x=5.6 or 5 3/5
Step-by-step explanation:
Cross multiplication is when you have two fractions (ratios) that are equivalent and you can multiply the numerator of the first one by the denominator of the second one, and the denominator of the first one by the numerator of the first one. The answers to these two are equivalent.
So, 5x/8 = 7/2
10x=56
x=5.6
x= 5 3/5
Answer:
30 is the perimeter i think 2 x 5 = 10 + 2 x 4.5 = 10 x 2 = 20 so 20 + 10 = 30
I think the area is 45, 5 x 4.5 = 22.5 and 2 x 22.5 = 45

Answer:
x > 3
Step-by-step explanation:
6x + 3 > 21 (Move the constant, +3 to the right hand side and change its sign)
6x > 21 -3 (Subtract 21-3)
6x >18 (Divide both sides by 6)
x > 3
It would be greatly appreciated if you gave me the brainlest
