Hello!
First, you'll need to find 20% of 150. You can do this by converting 20% into a decimal. To do so, you'll need to move the decimal place twice to the left to get 0.20. Now you'll need to multiply 150 by 0.20. Once you've done that, you should get $30. Now to find how much Romy paid in total, you'll need to add $30 to $150.
Romy in total payed $180 for the bill
I hope this helps!
Answer: m=2, b=-3
Explanation: rewrite in slope intercept form - y=2x-3. Subtracting is the same as adding therefore it becomes, y=2x+(-3) then using the formula- y=Mx+b identify the slope which is 2 then identify the y-intercept which would be -3.
Hope that helps! Have a good day :)
Answer:
square root of 5 squared minus 4 squared
Step-by-step explanation:
a^2 + b^2 = c^2
c^2 - b^2 = a^2
5^2 - 4^2 = a^2
25 - 16 = a^2
9 = a^2
√
√9=a
a=3
or
a= √25-16
a= √9
a=3
Hope this helps!
