Answer:
Option B : 38/2 is the correct answer.
Step-by-step explanation:
Given that:
Distance to travel = 38 miles
Speed of object = 2 miles per hour
Distance = Speed * Time
To find the time, we will divide the distance by speed.
Time = 
Putting values of distance and speed in the formula.
Time = 38/2
Hence,
Option B : 38/2 is the correct answer.
If 7% interest is compounded annually, then the value of the $500
after 'Y' years in the future is
$500 (1.07)^to the 'y' power .
For this exercise, it's $500 (1.07)⁴ = $ <u>655.40</u> .
Answers:
- Sarah has $12.50
- Sam has $27.50
- Casey has $55
======================================================
Explanation:
x = amount of money Sarah has
x+15 = amount of money Sam has, since he has $15 more than her
2(x+15) = amount of money Casey has, since he has twice as much as Sam.
Let's add up those three expressions and set that sum equal to 95
Solve for x.
Sarah + Sam + Casey = 95
x+(x+15) + 2(x+15) = 95
x + x + 15 + 2x + 30 = 95
4x+45 = 95
4x = 95-45
4x = 50
x = 50/4
x = 12.50
This says that Sarah has $12.50
That must mean Sam has x+15 = 12.50+15 = 27.50 dollars
And Casey must have 2*27.50 = 55 dollars.
----------------
As a check,
Sarah+Sam+Casey = 12.50+27.50+55 = 95
So the answer is confirmed.
You would take 180•15% to get 27 then you would subtract 180-27 to get 153. After you do the first you would do 200•20% to get 40 200-40=160 so the cheaper one would be the 180 because about 15% discount it’s 153 and 160>153
Answer:
a. (x+5)^2 = 49
b. (x+7)^2 = (x+1)^2
Step-by-step explanation:
So the term "a number" is always going to be x. input x into the sentences. "X plus five, then squared, is forty-nine". when they do "is __", that means equal to. In the second question, seven more than x is x + 7 (the two numbers are interchangeable here). Equivalent also means equal. hope this helped :)
