Is the same as seven less than a number(x) : x-7
now in your case what would be the answer ?
Answer:
x=3130/3
Step-by-step explanation:
3,125 = 5-10 + 3x
5-10+3x=3125
3x-5=3125
3x-5+5=3125+5
3x=3130
3x/3 = 3130/3
x=3130/3
I hope this helps!
The mathematical expression for the given statement is 50 + 10x
<h3>How to write a mathematical expression for this statement?</h3>
The given parameters are:
Initial distance = 50 laps
Rate of increment = 10 laps each week
Represent the number of weeks with x
So, we have:
Number of laps = Initial distance + Rate of increment * Number of weeks
This gives
Number of laps = 50 + 10 * x
Evaluate
Number of laps = 50 + 10x
Hence, the mathematical expression for the given statement is 50 + 10x

Answer: The correct answer is Choice D.
Step-by-step explanation: The correct answer is choice D.
Y = the total amount money that Kelly earned
X = the cost of each manicure
So, in choice D, the total amount that Kelly earned equals 12 times the cost of the manicure plus the 60 in tips that she received for the day.
Answer:
x = 23
y = 110
Step-by-step explanation:
70 and 3x+1 are alternate exterior angles and that means they are equal
70 =3x+1
Subtract 1 from each side
69 = 3x
Divide by 3
69/3 =3x/3
23 =x
70 and y are same side exterior angles and that means they are supplementary ( add to 180)
70+y = 180
y = 180-70
y = 110
