X - 3 = 2x - 13
+x +x
-3 = 3x - 13
+13 +13
10 = 3x
10/3 3/3
3.3 = x
You may either multiply the numbers or the place value, and both methods will yield the same answer.
(2 thousands, 7 tens) multiplied by 10 results in
... (20 thousands, 70 tens)
or
... (2 ten-thousands, 7 hundreds)
The volume provided is 3Pi(x^3) with a radius of x. To determine the volume of a cone, the formula used is V= [1/3]Pi(r^2)*height. By substituting, we get [1/3]Pi(r^2)x = 3Pi(x^3). This simplifies to (r^2)x = 9(x^3). Eventually, we find that r^2 = 9x^2, which leads to r = sqrt[9x^2] = 3x. <span>Answer: r = 3x</span>
Answer:
Robyn's model is logical, while Mark's is illogical.
Step-by-step explanation:
This question doesn't require calculations. What we need to do is analyze each model logically.
Mark's
Mark's representation indicates 20 instead of 2, which signifies that 200 is ten times greater than 20, making it nonsensical.
Robyn's
Robyn's representation displays 2, suggesting that 200 is 100 times greater than 2, which is not only accurate but also reasonable since 100 * 2 equals 200.
Hello! Dividing or multiplying a decimal by 10 is simpler than it may seem. When dividing by 10, shift the decimal point one place to the left. Conversely, when multiplying a decimal by 10, move the decimal point one place to the right. In this case, dividing 12.5 by 10 means shifting the decimal left one position, resulting in 1.25. Therefore, Lauren has covered 1.25 miles. To verify, you can multiply 1.25 by 10, which returns you to 12.5. The answer is 1.25! I hope this is helpful!
