Answer: he has 7 dimes and 9 quarters.

Step-by-step explanation:

The worth of a dime is 10 cents. Converting to dollars, it becomes

10/100 = $0.1

The worth of a quarter is 25 cents. Converting to dollars, it becomes

25/100 = $0.25

Let x represent the number of dimes that she has.

Let y represent the number of quarters that she has.

Jayden has 2 more quarters than dimes. This means that

y = x + 2

Jayden has $2.95 wroth of dimes and quarters . This means that

0.1x + 0.25y = 2.95 - - - - - - - - - - - 1

Substituting y = x + 2 into equation 1, it becomes

0.1x + 0.25(x + 2) = 2.95

0.1x + 0.25x + 0.5 = 2.95

0.35x = 2.95 - 0.5

0.35x = 2.45

x = 2.45/0.35

x = 7

y = x + 2 = 7 + 2

y = 9

How much money would a person have 8 years after they invested $2,000 into an account that has an annual interest rate of 3% tha
madam [21]

The amount of money the person would have in 8 years s $2541.74.

<h3>How much would the person have in 8 years? </h3>

The formula for calculating future value is:

FV = P (1 + r)^nm]

Where:

FV = Future value
  • P = Present value = $2000
  • R = interest rate = 3% / 12 = 0.25%
  • m = number of compounding = 12
  • N = number of years = 8 years

Value of the account in 8 years with monthly compounding = $2000(1.0025)^(12 x 8) = $2541.74

The Earth has a diameter
mrs_skeptik [129]

Answer:

<em>L = 24,873.6 miles</em>

Step-by-step explanation:

<u>Length of the Circumference</u>

Given a circle of radius r, the length of the circumference, or line surrounding the shape is:

L =2\pi\cdot r

The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:

r=7,917.5/2=3,958.75 miles

Assuming a plane flies around the equator at ground level, the distance it would travel is:

L =2\pi\cdot 3,958.75\ miles

L = 24,873.6 miles

Solve equation for 5x-14=8x+4
creativ13 [48]
My answer-

Simplifying 5x + -14 = 8x + 4
 
Reorder the terms: -14 + 5x = 8x + 4 Reorder the terms: -14 + 5x = 4 + 8x
 
Solving -14 + 5x = 4 + 8x Solving for variable 'x'.


Move all terms containing x to the left, all other terms to the right. Add '-8x' to each side of the equation. -14 + 5x + -8x = 4 + 8x + -8x

Combine like terms: 5x + -8x = -3x -14 + -3x = 4 + 8x + -8x

Combine like terms: 8x + -8x = 0 -14 + -3x = 4 + 0 -14 + -3x = 4 Add '14' to

 each side of the equation. -14 + 14 + -3x = 4 + 14

Combine like terms: -14 + 14 = 0 0 + -3x = 4 + 14 -3x = 4 + 14

 Combine like terms: 4 + 14 = 18 -3x = 18 <span>

Divide each side by '-3'. x = -6

Simplifying x = -6
