What is the solution to the equation?

AleksandrR [38]

Solution of the equation: $x=6\frac{1}{2}$

Step-by-step explanation:

The equation that we have to solve in this problem is:

$13\frac{3}{4}+x=7\frac{1}{4}$

The first step to do is to rewrite the mixed fractions as improper fractions. We have:

$13\frac{3}{4}=\frac{13\cdot 4+3}{4}=\frac{52+3}{4}=\frac{55}{4}$

And

$7\frac{1}{4}=\frac{7\cdot 4+1}{4}=\frac{29}{4}$

So the equation becomes

$\frac{29}{4}+x=\frac{55}{4}$

Now we multiply by 4 each term on both sides, and we get

$29+4x=55$

Now we subtract 29 from both sides,

$4x=55-29=26$

And finally, we divide both sides by 4:

$x=\frac{26}{4}=\frac{13}{2}=6\frac{1}{2}$

Tamita is making popcorn balls. She has 18.5 ounces of syrup. The recipe says that each batch of popcorn balls needs 4 ounces of

bija089 [108]

Answer:

4 batches

Step-by-step explanation:

Total syrup made by Tamita = 18.5 ounces

Amount of ounces per batch = 4 ounces

If 1 batch = 4 ounces

x batches = 18.5 ounces

Cross multiply

4 * x = 18.5

x = 18.5/4

x = 4.625

Hence she can only make 4 batches of syrup
