Hey what is 2(1+5x)-3x=72

x = 10

Step-by-step explanation:

Rearrange terms

2(5+1)−3=72

Distribute

10+2−3=72

Combine like terms

7+2=72

Subtract 2 from both sides of the equation

7+2−2=72−2

Simplify

7=70

Divide both sides of the equation by the same term

7/7=70/7

Simplify

= 10

if you could give brainliest that would be awesome! :))

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

false

inverse variation is not exponential
