6 over 8 and or you can do 9 over 12 because you can multiply the numerator and the denominator with any number but what you do to the top has to be the same as the bottom. I multiplied the first one with 2 on the denominator and the numerator. I multiplied the second one with 3 and what you do to the bottom has to be the same as the top

Answer:
(i) Equation
(ii) 10 weeks
Step-by-step explanation:
The scenario is an equation and not an inequality , this is because the number of sit - ups Amelia planned to do is specific , which is 50 , had it been the question used the word like at least , at most 50 , it would have been an inequality.
The question is an example of Arithmetic sequence
From the statement ;
The first term = 5
The common difference = 5 ( since Amelia planned to add 5 more sit - ups to her training schedule each week )
The formula for the nth term of an Arithmetic sequence is given by :
= a + (n- 1 )d
= 50
a = 5
d = 5
n = ?
substituting the values , we have
50 = 5 + (n - 1 ) x 5
50 = 5 + 5n - 5
50 = 5n
n = 10
Therefore , it will take Amelia 10 weeks to reach her goal of 50 sit - ups
3(9) = 27
3(7) = 21
3(9+7) = 48
27+21 = 48
48=48
Answer: No
Step-by-step explanation:
Is 1/4 (8y -12) equivalent to 2y - 12? No. 1/4 (8y-12) equals out to 2y-3 not 2y-12. To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1
