Answer: red is 21, green is 14 and blue is 7
Step-by-step explanation:
Let r represent the length of the red stick.
Let g represent the length of the green stick.
Let b represent the length of the blue stick.
The red one is three times as long as the blue. This means that
r = 3b
The green one is 7 inches longer than the blue. This means that
g = b + 7
The blue and green together are the same length as the red. This means that
b + g = r
g = r - b
Therefore
b + 7 = r - b
r = b + b + 7 =2b + 7
Substituting r= 3b into r = 2b + 7, it becomes
3b = 2b + 7
3b - 2b = 7
b = 7
r = 3b = 3 × 7 = 21
g = b + 7 = 7 + 7 = 14

The answer for the given above is letter "a, -6r2s4t3". This is obtained by dividing 18 by -3 and subtracting the exponent below with that from above of the same variable. For r, subtract 2 from 4 to get 2. For s, subtract 1 from 5 to get 4 and lastly for t, subtract 3 from 6 to get 3.
Answer:
<h2>- i</h2>
Step-by-step explanation:
Answer:
2/3 = 8/12
3/4 = 9/12
Step-by-step explanation:
whatever you do to the denominator, you have to do the the numerator.
2/3 - 3 times 4 equals 12 and 2 times 4 = 8. so 2/3 = 8/12
3/4 - 4 times 3 equals 12 and 3 times 3 equals 9. so 3/4 = 9/12
hope this helps!!!
