Answer:
Algebraic expression representing number of coffee B = 100-x
Step-by-step explanation:
An algebraic expression is an expression that contains unknowns denoted with alphabets or symbols and natural numbers.
Coffee blend is 100 pounds and x represent number of pounds of coffee A
Hence coffee B = 100-x
Algebraic expression representing number of coffee B = 100-x
15, because 3 goes into 9, 3 times and, 4 goes into 12, 3 times therefore x has to follow this rule because these 2 triangles are similar and because it already gives you 5 just take 5*3=15 there is your answer enjoy!=)
Answer:

Step-by-step explanation:
We need to sum the following two expressions:


expanding the polynomial in the numerator:


This is the most simplified form we can get:

Answer: y = 11.50x
Step-by-step explanation:
linear function format:
y = mx + b
since its linear and it starts from 0, b is 0 since there is no addon
y = mx
x is the number of hours, y is the payment incrementing by 11.50 per hour, making 11.50 our gradiant
So y = 11.50x
1 hour = 11.50 * 1
2 hour = 11.50 * 2 and so on
