Answer:
it is d because they dont have enuff info :)
B - 3A = 2
3B - 6A = 12
(2)B - (6)A =4
3B - 6A = 12
Subtract
-B = -8
B = 8
Plugin 8 for B
8 - 3A = 2
8 = 3A + 2
6 = 3A
2 = A
(Double checking)
3(8) - 6A = 12
-6A = 12-24 = -12
- 6A = -12
Divide by -6
A= 2
It works
A = 2. B = 8. Hope this helps
Answer:
Examine the mathematical expression you're working on. For example, suppose you're given 5x + 3. There are two terms here, 5x and 3. Look for the variable. In this case, x is the variable. In your case its c
Find the numerical coefficient of x. Remember to look for the number before the variable. In this case, 5 is the numerical coefficient. The term 3 is a constant and is separated from the variable by a plus sign.
Keep an eye out for negative coefficients. For example, suppose you're given the statement -y + 7 + 98. You would first identify the variable, y.
Look for the numerical coefficient of y. In this case, a "1" is implied before the variable, but it's negative in this instance. Therefore, the coefficient of y is negative 1.
Answer:
1 is in the unit place and 7 is in the tenths place and the fraction for this is 1 and 7/10 the one is a whole number and the seven tenths is a fraction and thats your answer
Answer:
Step-by-step explanation:
Apply Distributive property:
Add like terms and then add 63 to both sides of the equation:
Pick the coefficient of the x term, divide it by 2 and square it:
Add it to both sides of the equation:
Rewriting the left side as a squared binomial, we get:
Apply square root to both sides:
And finally we need to add 1 to both sides of the equation. Then we get:
