Is 6/12 and 15/30 proportional?
Answer:
yes
Step-by-step explanation:
6 is half of 12. 15 is half of 30. The ratios are equal, so the fractions are proportional.
Answer: yes
Also, you can reduce both fractions.
Divide the numerator and denominator of 6/12 by 6 to get 1/2.
Divide the numerator and denominator of 15/30 by 15 to get 1/2.
Since both fractions reduce to 1/2, 6/12 and 15/30 are equivalent fractions and are proportional.

What is the function rule of dividing by 4?
Answer:
division
Step-by-step explanation:
answer boom.... is it right... wait it better be....... nevermind
Answer:
The divisibility rule for 4 is that if the number formed by the last two digits in a number is divisible by 4, the original number is divisible by 4
ex:
3944
take a look at the last two digits
⇒ 44
we know that 44 can be divided by 4
⇒ 44 ÷ 4 = 11
therefore, the whole number, 3944, can be divided by 4
⇒ 3944 ÷ 44 = 986
Find the common difference of the arithmetic sequence -7, -1 ,5
Using zero product property, find the values of x. (Hint: You must set factored parts equal to 0). (x+10)(2x-4)=0
I know there are two answers but I need an explanation please!! I want to understand this
Answer:
x = - 10, x = 2
Step-by-step explanation:
Given
(x + 10)(2x - 4) = 0
Equate each factor to zero and solve for x ( zero product property )
x + 10 = 0 ⇒ x = - 10
2x - 4 = 0 ⇒ 2x = 4 ⇒ x = 2
