How many solutions does this system have?

X+ 4y = 6
y=2x-3

O one
O two
O an infinite number
Ono solution

B. two (2)

Step-by-step explanation:

x + 4y = 6

y = 2x - 3

Substitution y

x + 4y = 6

x + 4(2x - 3) = 6

x + 8x - 12 = 6

9x = 6 + 12

9x = 18

x = 18/9

x = 2

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

you probably already have the answer but anyways it's b. 15.0
