<h2>Answer:</h2>

<em><u>Percent value of A with respect to Percent value of B is,</u></em>

30\%

<h2>Step-by-step explanation:</h2>

In the question,

Let us say the value of the Baseball card A and B initially is = 100x

So, for Baseball card A in first 5 years percent increase = 20%

So,

Value after 5 years = 100x + 20% of 100x = 120x

<u>After 5 more years,</u>

Percent decrease = 50%

So,

<u>Value at the end of 10 years = 120x - 50% of 120x = 60x</u>

Now,

For Baseball card B, Percent increase in 10 years = 100%

So,

<u>Value of card B = 100x + 100% of 100x = 200x</u>

So,

<em><u>Percent value of A with respect to Percent value of B is,</u></em>

\frac{60x}{200x}\times 100=30\%

Liliana use for dark power crystals to raise 14 zombie soldiers she wants to know how many zombie soldiers Z she can race with 1
laiz [17]

Answer:

140 zombies

Step-by-step explanation:

Since this is a proportions problem and we are given three values and a variable we must solve for which is the number of zombie soldiers she can raise (z) with 10 dark power crystals. Therefore, we can use the rule of three to solve for this, in which we multiply the diagonal values and divide by the last remaining value in order to solve for the variable like so...

1 crystal <===>  14 zombies

10 crystals  <===>   Z zombies

(10 * 14) / 1 = 140 zombies

Lady_Fox [76]

Answer:

x = 13

y = 15

Step-by-step explanation:

ST = DT ( Reason : from given )

5x = 65

x = 65 / 5

x = 13

TY = TU ( Reason : from given )

3y + 5 = 50

3y = 50 - 5

3y = 45

y = 45 / 3

y = 15
