Step-by-step explanation:
John said he can find 38×10 by adding a 0 to the end of 38 to get 380. John finds 46.52×10 using the same method and gets 46.520.
For the first one that is, 38 × 10 = 380, John is correct. For the second one, that is, 46.52 × 10 = 46.520. John is incorrect. In this case, the first one is correct because John was multiplying by a whole number.
For the second one involving a decimal, John could have shifted the decimal point one place to the right and not add 0 to the end. Then he will get:
46.52 × 10 = 465.2
Answer:
B
Step-by-step explanation:
Two numbers are relatively prime when there is no integer greater than one that that is a factor of both of them.
A: 15 and 21 both have a factor of 3.
<u>B</u>: 24 and 49 have no common factors, and therefore, are relatively prime.
C. 35 and 135 both have a factor of 5.
D: 45 and 102 both have a factor of 3.
Answer:
Step-by-step explanation:
f(x) = -3x + 4 and g(x) = 2,and
f(x) = g(x)
Then: -3x + 4 = 2
-3x = 2 - 4
-3x = -2
x = -2/-3
x = 2/3
The first step would be to add 40 to both sides of the equation, you can use multiple methods to solve from there, but I recommend 'completing the square' since your b value is equal to zero :)
