Answer:
The answer is B. input 60 output sq root 3/2
Step-by-step explanation:
A) 75 and 25 coefficients
X and y variables
B) 2 terms 75x and 25y
C) 75$
D
Explanation
Step 1
Let
x represents the smallest number:
as those are three consectutive intergers, the next interger is:
this is the middle number:
middle number=x+1
the next consectutive number is
so, the third number is x+2
Hence,
Step 2
the sum of the smallest number and twice the middle
number is equal to 20 more than the third number?
replacing:
twice the middle=2(x+1)
so, the answer is
D
Answer:
80 sets costing $25/set
120 sets costing $45/set
Step-by-step explanation:
let x = number of sets costing $25/set
let y = number of sets costing $45/set
we have to build eqautions form the info given
(1) . total sets = 200 x + y =200
(2) . total sets = 7400 25x + 45y = 7400
use the substitution method

Option B... The triangles can be proven congruent using SSS. For those on Edg.
