What is the value of x?

anygoal [31]

Answer:

Step-by-step explanation:

There are the vertical angles. The vertical angles are congruent. Therefore we have the equation:

$7x-8=6x+11$ <em>add 8 to both sides</em>

$7x-8+8=6x+11+8$

$7x=6x+19$ <em>subtract 6x from both sides</em>

$7x-6x=6x-6x+19\\\\x=19$

bekas [8.4K]

Answer:

The water she need is $7\frac{7}{8} \ cups.$ and strawberry syrup $11\frac{13}{16}\ cups$ .

Step-by-step explanation:

Given:

Dina wants to make 15 3/4 cups of strawberry drink by mixing water and strawberry syrup with a ratio of 2 1/4 cup of water for every 3/4 cup of syrup.

Now, to find the quantity of water and syrup she need to use.

As given in question ratio so:

Strawberry syrup = 2 1/4 = 9/4.

Water = 3/4.

Total cups of strawberry drink = 15 3/4 = 63/4.

Let the strawberry syrup be $\frac{9}{4} x$ .

And let the water be $\frac{3}{4} x$ .

According to question:

$\frac{9x}{4} + \frac{3x}{4}=\frac{63}{4}$ .

<em>On adding the fractions:</em>

⇒ $\frac{9x+3x}{4} =\frac{63}{4}$

⇒ $\frac{12x}{4} =\frac{63}{4}$

<em>Multiplying both sides by 4 we get:</em>

⇒ $12x=63$

<em>Dividing both sides by 12 we get:</em>

⇒ $x=\frac{63}{12}$

<em>Dividing numerator and denominator by 3 on R.H.S we get:</em>

⇒ $x=\frac{21}{4}$

Now, putting the value of $x$ on ratios:

Strawberry syrup = $\frac{9}{4}\times x=\frac{9}{4}\times\frac{21}{4}$

= $\frac{189}{16}$

= $11\frac{13}{16}\ cups$

Water = $\frac{3}{4}\times x =\frac{3}{4} \times\frac{21}{4}$

= $\frac{63}{8}$

= $7\frac{7}{8} \ cups.$

Therefore, the water she need is $7\frac{7}{8} \ cups.$ and strawberry syrup $11\frac{13}{16}\ cups$ .
