Answer: 7/3
Step-by-step explanation:
To divide fractions, you can use the "keep, change, flip" method.
1. Keep the first fraction (7/9) as is.
2. Change the division sign to a multiplication sign.
3. Flip the second fraction (i.e. find the reciprocal). This means 1/3 changes to 3/1.
Rewrite the equation:
7/9 x 3/1
Multiply the numerators and the denominators together, respectively.
21/9
Simplify:
7/3
Answer:
4. No because 2×4=8 but 5×4 doesn't equal 18
3/5(15d+20)−1/6(18d−12)=38
Simplify
3/5(15d+20)−1/6(18d−12)=38
(3/5)(15d)+(3/5)(20)+−3d+2=38(Distribute)
9d+12+−3d+2=38
(9d+−3d)+(12+2)=38(Combine Like Terms)
6d+14=38
Subtract 14 from both sides.
6d+14−14=38−14
6d=24
Divide both sides by 6.
6d/6 = 24/6
d=4
Method 1: Realize that the desired equation will look exactly the same as the given equation 3x − 4y = 6, except that the constant will be different.
Thus, the equation of the new line is 3(-2) − 4(6) = C, where C comes out to 30.
Then the new line is 3x - 4y = 30.
The answer to the question is y=2
