Answer:
e = 7
Step-by-step explanation:
Eliminate parentheses using the distributive property.
18e -48 = 5e +43
13e -48 = 43 . . . . . . . . subtract 5e from both sides
13e = 91 . . . . . . . . . . . . add 48 to both sides
e = 7 . . . . . . . . . . . . . . divide both sides by 13

<em>Comment on equation solving</em>
If there are parentheses or fractions, it usually works well to eliminate those. The distributive property is used to eliminate parentheses. Fractions can be eliminated by multiplying the equation by the denominator. (We mean 'multiply both sides of the equation by the denominator'.) If you have excellent skill with arithmetic using fractions, you don't need to go to the trouble to eliminate them.
After the numbers in the equation are mainly integers or decimals, the next step is to look to see where the variable of interest is located. You want to do what it necessary to put all of the variable terms on one side of the equal sign, and everything else on the other side. The procedure generally is to decide what you don't want, and subtract that from both sides of the equation.
Finally, you divide by the coefficient of the variable, so the variable stands alone on one side of the equal sign. This shows you the solution.
Between two square roots of integers, you can find pi are square roots
<h3>Between which two square roots of integers can you find pi?</h3>
In mathematics, the square root of a number x is a number y such that y2 = x. Another way to put this is to say that a square root of x is a number y whose square equals x.
The number that, when multiplied by itself, results in the value that is sought is referred to as the number's square root.
Since 3 < pi < 4,
√9 < pi √16
In conclusion, what this demonstrates is that the value of pi may be found anywhere between the square roots of -9 and -10.

Answer:
17
Step-by-step explanation:
Pythagorean theory baby! Okay so the Pythagorean theory is a² + b² = c² so lets draw a triangle and label our sides. So we know 8² + 15² = c² so I'm going to find the square root of all of our numbers. We get 64 + 225 = c² so then add 64 + 225 = 289 then I take the square root of 289 which equals 17 . This answer also makes sense because out hypotenuse should always be bigger then the legs.
I'm pretty sure thats right, Hope this helps.
Answer:
C
Step-by-step explanation:
Two pyramids are similar. It means that their side lengths are proportional.
So, let's see the proportionality constant from SMALL PYRAMID to LARGE PYRAMID.
The corresponding length of 8 in small pyramid is 24 in large pyramid. We ask ourself: "8 times WHAT gives us 24?"
This is the proportionality constant (aka "k").
So, 8 times "3" is 24. So the proportionality constant is "3".
k = 3
Now, the height of small pyramid is 6 and height of large pyramid is "x". These sides will be same way proportional. So, we can say:
6 times the proportionality constant (3) would give us x
So,
6 * 3 = x
x = 18
Correct answer is C
X equals 13/3 and Y equals 1/13 sorry if I am wrong
