Answer:
the answer would be 270
Step-by-step explanation:
i can explain later:
since x = 5, you plug it in f = 4x +7, and you get f = 27 and since 1/2x is in the denominator, it will flip over and become 2x. 2x is 10, so you multiply f by g and get 270 which is if f/g(5) is the question.
Determine if the two ratios are equivalent in this problem
The two ratios are equivalent
Given:
4 over 6 times 14 over 21
Times mean multiplication (×) in mathematics
Over means division (÷ or /) in mathematics
So,
4 over 6 times 14 over 21
= 4/6 × 14 / 21
Equate both ratio
4/6 = 14/21
cross product
(4 × 21) = (6 × 14)
84 = 84
Therefore, the two ratios are equivalent

Answer:
12<x≤12.2
Step-by-step explanation:
To fit in an existing frame, the length, x, of a piece of glass must be longer than 12 cm but not longer than 12.2 cm.
The length of frame is x cm.
Length of frame must be longer than 12 cm.
Inequality, x>12
Length of frame not longer than 12.2 cm
In equality, x≤12.2
Now we make compound inequality of question
"Length of frame, x must be longer than 12 cm and not longer than 12.2 cm"
Inequality: 12<x≤12.2
Length of glass fit in the frame, 12<x≤12.2
Hence, The inequality 12<x≤12.2
