The number of dime Jenna have is 15 and the number of quarter Jenna have is 35.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Every evening Jenna empties her pocket and puts pockets and puts her change in a jar.

At the end of the week, she counted her money.

One week she had 50 coins all of them were dimes and quarters.

When she added them up she had a total of $10.25.

Let d be the number of dimes and q be the number of quarters.

Dimes = $ 0.10

Quarter = $ 0.25

Then the equation will be

d + q = 50 ...1

0.10d + 0.25q = 10.25 ...2

By solving equations 1 and 2, we have

d = 15 and y = 35

Then the number of dime Jenna have is 15.

60% of a museum’s fossils are from the Jurassic Period. If the number of fossils from the Jurassic period is 15, what is the tot

Keith_Richards [23]

Answer : The total number of fossils at the museum are, 25

Step-by-step explanation :

As we are given that 60% of a museum’s fossils are from the Jurassic Period.

Let the total number of fossils at the museum be, 'x'

Given:

Number of fossils from the Jurassic period = 15

The % of a museum’s fossils are from the Jurassic Period = 60%

Thus, the expression will be:

$\frac{15}{x}\times 100=60$

By solving the term 'x' we get:

$x=\frac{15}{60}\times 100$

$x=25$

Thus, the total number of fossils at the museum are, 25

Explain how to find the missing exponent given the base and the value

drek231 [11]

Answer:

To find the value of missing exponent, we have to split the number which is in other side of equal sign (which is not having power) as the multiple of base of the missing exponent.

On both sides, powers have the same base, so their exponents must be equal.

Step-by-step explanation:

<h3>Problem 1:</h3>

Write the missing exponent:

25=5^x

Let x be the missing exponent.

To find the value missing exponent, we have to split the number which is in the left side as the multiple of the base of the missing exponent.

That is,

25=5*5 or 5^2

Now,

5^2=5^x

Powers have the same base so their exponent must be equal.

Hence the missing exponent is 2
