Emily is 17 because if you divide 26 by 2 and get 13 then add 4 to it to get 17 then grace would also 9 years old.
So hmm check the picture below
solve for KL
Answer:
x=(-15±√(79) all over 4
Step-by-step explanation:
You can do this in a few ways but I used the quadratic formula for it. Just plug the numbers into this equation: x= -b ± √(b-4ac) all over 2a.
In this case a=2, b=15, c=-8
Also, there wasn't an "x" behind 15 so I'm doing this by assuming that there is one.
<em> 4 1</em>
<em>u + -- = 2 ---</em>
<em> 5 3</em>
<em> 1 2 * 3 + 1 7</em>
<em>2 ---- = ---------------- = ------</em>
<em> 3 3 3</em>
<em>Now we have to do</em>
<em> 4 7</em>
<em>u + -- = ---</em>
<em> 5 3</em>
<em> 7 4 7 * 5 - 4 * 3</em>
<em>u = ------- - ----- = ------------------------ </em>
<em> 3 5 3 * 5</em>
<em> 35 - 12 23</em>
<em>u = ------------------ = ------</em>
<em> 15 15</em>

6/8 = 3/4 pounds
Step-by-step explanation:
Step 1 :
From the number line we can see that
1 bag of grapes has weight of 1/8 pounds
4 bags of grapes has weight of 1/4 pounds
3 bags of grapes has weight of 3/4 pounds
Step 2 :
The total number of bags having a weight of minimum 3/8 pounds is 1 + 4 + 3 = 8
The total weight of bags that has weight of minimum 3/8 pound is
1/8 + 1/4 + 3/ 8
= 1/8 + 2/8 + 3/8 ( L.C.M is 8)
=6/8 =3/4 pounds
