Answer:
a = 12
Step-by-step explanation:
a+b+c+a+c+b+a+c = 12+a+a+b+b+c+c+c
=> 3a + 2b + 3c = 12 + 2a + 2b + 3c
=> 3a - 2a + 2b - 2b + 3c - 3c = 12
=> a = 12
Answer to Question 1:
Is this how you want it to be like? Tell me if this is okay:
<u>Row 1 of the table</u>
Statement: write the equation in Slope-intercept form (y=mx+b)
Reason: you can clearly see what the m (slope) is In the equation
<u>Row 2 of the table</u>
Statement: find the coefficient of x (the slope, m) in the new written Slope-intercept equation
Reason: the coefficient of x is the number that’s being multiplied by the variable x. In Slope-intercept form, it’s written as y=mx+b, where m is the slope because it’s the coefficient of x.
Question 2: Sorry, Question 2 is still too hard for me. It’s not at my level :( but hopefully my answer to Question helps you out :)
Exponent rule : a^-x = 1/a^x
x^-9 * x^-2 =
1/x^9 * 1/x^2 = (when multiplying exponents with same base, add exponents)
1/x^(9 + 2) =
1/x^11
1 kilo gram is 1000 grams. 1 gram is 1000 milligrams. Think you can solve the rest? :)
