X=?
AB=?
BC=?

X=5

AB=13

BC=17

Step-by-step explanation:

So first you add the two equations together and the total will have to be 30.

So, 2x+3-4x-3=30

Simplified 6x=30

x=5.

2x+3 -> 5 times 2 + 3

4x - 3 -> 5 times 4 - 3

Step-by-step explanation:

AB + BC = AC

2x +3 + 4x - 3 = 30

2x + 4x + 3 - 3 = 30

Combine like terms

6x = 30

Divide both sides by 6

x = 30/6

x = 5

AB = 2x + 3 = 2*5 + 3 = 10 + 3

AB = 13

BC = 4x - 3 = 4*5 - 3 = 20 - 3

BC = 17

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

can i see the following ?
