Susie has 3 1/5 pounds Of jellybeans. Julie wants to combined his 2 1/3 Pound bag of licorice with Susie's jellybeans. What woul
Naily [24]

Answer:

The Total Weight of candy is  5\frac{8}{15} \ pounds.

Step-by-step explanation:

Given:

Amount of Jelly beans Susie have = 3\frac{1}{5} pounds

3\frac{1}{5} can be rewritten as \frac{16}{5}

Also Given;

Julie has amount of licorice =2\frac{1}{3} pounds

2\frac{1}{3} can be Rewritten as \frac{7}{3}

Now Julie wants to combined her bag of licorice with Susie's jellybeans.

Hence the Total weight of candy will be the sum of Amount of Jelly beans and amount of licorice.

Total weight of candy = \frac{16}{5} + \frac{7}{3}

Now making the Denominator common we get;

Total weight of candy = \frac{16\times3}{5\times 3} + \frac{7\times5}{3\times5}= \frac{48}{15} + \frac{35}{15}=\frac{48+35}{15}= \frac{83}{15} \ pounds

\frac{83}{15} \ pounds can be Rewritten as 5\frac{8}{15} \ pounds

Hence The Total Weight of candy is  5\frac{8}{15} \ pounds.

Four times a number increased by 3 is the same as twice the number increased by 9? I'm horrible at these
Anna71 [15]
The question says:
4(x) +3 = 2(x) + 9 
so now you need to find x
first you should add -2(x) on both sides of the equation and then add -3 on both sides:
4(x) - 2(x) = 9 - 3 
2(x) = 6
now you can divide both sides by 2:
x = 6/2 
x = 3 :)))
I hope this is helpful

The local school sponsored a mini-marathon and supplied 84 gallons of water per hour for the runners. What is the amount of wate
Dmitrij [34]
All you need to do is multiply 84 by 4. 

The number of gallons by the number of quarts <em>in a gallon. </em>

80*4= 320

4*4=16

320+16= 336

There are 336 quarts of water supplied an hour. 

I hope this helps!
