Answer:
4+6n=7
n=1/2
Step-by-step explanation:
put the numbers in and n= a number
Cross multiply: 20 * b = 45 * 34
Simplifying: 20 * b = 45 * 34
Multiply 45 * 34: 20b = 1530
Solving: 20b = 1530
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Divide each side by '20': b = 76.5
Simplifying: b = 76.5
To number 1 your answer is 100 + 5x < 300 because she wants to spend less than 300 and has to pay 5 dollars per hour, x, along with 100 for the day. to number 2 your answer is x < 40 bc when you subtract 100 from both sides you get 5x < 200 then divide both sides by 5 getting you x < 40
