Answer:
1: something because you didn't give another number. For example, 1:2 is 1 golf ball to 2 golf tees. A ratio is one thing comparing to another. Hope this helps! I learned this in 6th grade. Brainly if so!
Step-by-step explanation:
Write and solve an equation of ratios:
6 inches 1 inch
-------------- = ------------
60 inches x
Cross-multiplying, 6x = 60, so x = 10 inches (answer)
Answer:
It's A.
Step-by-step explanation:
Because whatever goes into the absolute value symbol, it'll turn out positive. And real numbers could only be positive.
First equation is: x - y = 12
x = 12 + y
Now, substitute this in 2nd equation,
2x - 3y = 27
2(12+y) - 3y = 27
24 + 2y - 3y = 27
-y = 27 - 24
y = -3
In short, Your Answer would be -3
Hope this helps!
Given:
The equation is
To find:
The value of x.
Solution:
We have,
![[\because \left(\dfrac{a}{b}\right)^{-m}=\left(\dfrac{b}{a}\right)^{m}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cleft%28%5Cdfrac%7Ba%7D%7Bb%7D%5Cright%29%5E%7B-m%7D%3D%5Cleft%28%5Cdfrac%7Bb%7D%7Ba%7D%5Cright%29%5E%7Bm%7D%5D)
![[\because a^ma^n=a^{m+n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5Ema%5En%3Da%5E%7Bm%2Bn%7D%5D)
On comparing the exponents, we get
Therefore, the value of x is 3.
