Try to put all the x-es on one side and then find a value of one x. In this case:
x + 36 = 4x / -x (both sides)
36 = 3x / :3 (both sides)
x = 12
Answer:
6%
Step-by-step explanation:
The probability of picking a maths student = 21% = 21/100
The probability of picking a science student = 15% = 15/100 = 3/20
The probability of picking in both = 6/100 = 3/50
The probability that the student is in maths or science = 21/100 - 15/100 = 6/100 = 6%.
You would start by setting up the equation:
7x=125 where x is equal to the number of books sold
x=17.9
Since you cannot sell .9 of a book, this must be rounded up to 18.
Therefore, Amy must sell 18 books.
The correct question is
<span>Ellie made a cube-shaped cardboard box with side-length s. The area of cardboard she used is given by the formula A = 6s2, where s represents the side length of the cube.
Which equation correctly solves the formula for s?
we know that
</span>A = 6s²---------> clear the variable s
s²=A/6------> applying square root both members
s=√(A/6)--------> s=(1/6)*√(6*A)
<span>
the answer is
</span>s=(1/6)*√(6*A)
12 yards, 3 feet, and 3 inches
