Answer: x = 8
<u>Step-by-step explanation:</u>
4x + 18 + 5x = 90
9x + 18 = 90 <em>Added like terms</em>
9x = 72 <em>Subtracted 18 from both sides</em>
x = 8 <em>Divided both sides by 9</em>
BONUS: The sum of these two angles is 90°, which means these angle are complementary.
In the given question there
are certain information’s based on which the answer to the question can be
easily reached.
Let us assume that the distance ran by Adam = x
The the distance ran by Julio = (x - 17) miles
It is also given that Julio had run 13 miles
The we can create an equation and that is
x - 17 = 13
x = 13 + 17
= 30
So Adam ran a distance of 30 miles.
The difference between the areas of Alaska and Rhode Island in square miles is 481.
What is "difference" in mathematics?
One of the most crucial mathematical operations, which is obtained by removing two integers, produces difference in mathematics. It reveals how much one number deviates from another. To determine how many numbers are between the two supplied numbers is the goal of finding the difference in math. The difference in mathematical notation is minus (-).
Given that Rhode Island is 392 square miles in size overall and Alaska is 873 square miles, the following calculation must be done to discover the difference between them:
873 - 392 = X
481 = X
Therefore, the difference in square miles is 481.
