Answer:
x=21/23
Step-by-step explanation:
Solve for x:
3x+5y=21−20x+5y
Add 20x to both sides:
3x+5y+20x=−20x+5y+21+20x
23x+5y=5y+21
Subtract 5y to both sides:
23x+5y+−5y=5y+21+−5y
23x=21
Divide both sides by 23:
x=21/23
Answer:
C: 6
Step-by-step explanation:
Let's work backward. If that ? is replaced by 6, we have:
x^2 + 12x + 36 = (x + 6)^2.
The coefficient in question is 6.
Answer:
(-4, 5)
Step-by-step explanation:
negative x positive y
1/4 + 3/8
Rewrite with the LCD (lowest common denominator)
Remember : the denominator is just the bottom number on a fraction.
Let's look at both of our given fractions denominator's.
4 & 8 → What do both of these numbers have in common? They both go into 8!
How many times does 4 go into 8? → Twice
How many times does 8 go into 8? → Once
So, because of that, we must multiply the top number (numerator) of each fraction with either one, or two.
First fraction : 1/4 × 2/2 =2/8 → So, our first fraction changes.
Second fraction : 3/8 × 1/1 = 3/8 → However, our second fraction changes.
So, our new question looks like this : 2/8 + 3/8
If you wanted us to answer this question, we simply need to add the top numbers (numerators) with one another because both fractions have the same bottom numbers (denominators).
2 + 3 = 5
So, our answer is 5/8 and our question rewritten with the LCD is : 2/8 + 3/8
