Given that the original price of the model boat kit is $67.53 and he has a coupon of $25 off if a purchase is $50 or more. Since the purchase is more than $50, we will deduct 25 from 67.53 so the discounted price of the model boat kit would be $42.53. Hope this answers your question.
Using the formula a(b+c) = ab + ac, then 7(2x-6) = 14x - 42. The answer is D.
Answer:
The temperature outside is 75.6°F
Step-by-step explanation:
We are given the following in the question:
The temperature of dry ice = - 109.3°F
Let x be the temperature outside in Fahrenheit.
It is given that the temperature of dry ice is 184.9°F less than the outside temperature.
Thus, we can write the equation:
Solving, the above equation, we get:
Thus, the temperature outside is 75.6°F
Answer:
y = $15.5x
Step-by-step explanation:
Given that
Tim earns $31 after 2 hours
$46.5 earns after 3 hours,
And, $62 earns after four hours
So first determine the each hour earnings i.e.
= $31 ÷ 2
= $15.5
In two hours it would be $31 and so on
So here the equation would be
y = $15.5x
Here
y = money amount
x = number of hours
