If b = the number of blue bikes, whtoh algebraic expression represents the
phrase below?
the sum of the number of blue bikes and the 9 red bikes
ОА. b+9
B. b•9
ОСІБ – 9
OD. b= 9

A: b + 9

Step-by-step explanation:

If it's the sum of two numbers it is addition, meaning that you add the number of blue bikes(b) to the number of red bikes(9).

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
