100% increase. If you think about it, a 50% increase in price would be 7.5 (15/2), so therefore a 100% increase would just be $15.

Jessica opened a bank account that earns 2 percent interest compounded annually. Her initial deposit was $100, and she uses the

klasskru [66]

Answer:

x = 1.02.

Step-by-step explanation:

The x is a factor worked out from the annual interest written as a decimal fraction.

So we have 2% = 2/100 = 0.02.

The amount at the end of the first year is $100 + 0.02*100

= $100* 1.02, and in the second year it will be $100* 1.02^t where t = 2 and so on.

So we see that x in the given expression is 1.02.

Five over seven plus blank over six equals fifty one over forty two

NISA [10]

Answer:

The blank is 3

Step-by-step explanation:

1 - Give the blank a variable

x = our blank

2 - Write it out

$\frac{5}{7} + \frac{x}{6} = \frac{51}{42}$

3 - Get the denominators equal

$\frac{5}{7}(\frac{6}{6}) +\frac{x}{6}(\frac{7}{7}) = \frac{51}{42} \\\frac{30}{42}+\frac{7x}{42} = \frac{51}{42}$

4 - Simplify

$\frac{30+7x}{42} = \frac{51}{42} \\ \frac{30+7x}{42} = \frac{51}{42}$

5 - Solve for the numerators

30+7x = 51

-30 -30

7x = 21

x = 3

Alla and balla together drink 750ML of water. Of alla drinks 50% more than balla how much does Alla drink

Akimi4 [234]

Answer:

450 ml.

Step-by-step explanation:

Let x be the amount of water drank by Alla and y be the amount of water drank by Balla.

We have been given that Alla and Balla together drink 750 ML of water. We can represent this information as:

$x+y=750...(1)$

We are also told that Alla drinks 50% more than Balla. We can represent this information as:

$x=1.5y...(2)$

From equation (1) we will get,

$y=750-x$

Upon substituting this value in equation (2) we will get,

$x=1.5(750-x)$

Upon distributing 1.5 to right hand side of the equation we will get,

$x=1125-1.5x$

Upon adding 1.5x to both sides of equation we will get,

$x+1.5x=1125-1.5x+1.5x$

$2.5x=1125$

Let us divide both sides of our equation by 2.5.

$\frac{2.5x}{2.5}=\frac{1125}{2.5}$

$x=450$

Therefore, Alla drank 450 ml of water.
