The value of x in the given similar triangles ADB and BCE is 4.5.

To solve for x in the given similar triangles ADB and BCE, we can set up the proportion of corresponding sides:

In triangle ADB, we have:

AB/BD = x/DE

Substitute the given values:

3/4 = x/6

Now, cross-multiply and solve for x:

3 * 6 = 4x

18 = 4x

x = 18/4

x = 4.5

So, the value of x is 4.5.

2000:$5.00 2015:6.50 what is the change in the cost of the cheeseburger

Answers

Change means “difference in price”. Difference means subtraction.....so:
New price - old price = difference
6.50 - 5.00 = 1.50

If you want per year, there were 5 years between prices so divide by 5:
1.50/5 = 0.30 per year. So 30 cents every year or $1.50 overall

Find the amount of the principal on a loan at 6% interest for 140 days if the interest was $253.15, using the exact interest method. (Round to the nearest whole dollar amount)

Answers

Answer:

$11,000

Step-by-step explanation:

Given that :

Time, t = 140 days = 140/365 = 0.3835years

Interest paid = 253.15

Interest % = 6%

Principal, p =?

Using the relation :

Interest = principal * rate * time

253.15 = p * 0.06 * (140/365)

253.15 = 0.0230136p

P = 253.15 / 0.0230136

P = 11000.017

Hence, the principal amount = $11,000

Let's solve for x.

4x+5y=7

Step 1: Add -5y to both sides.

4x+5y+−5y=7+−5y

4x=−5y+7

Step 2: Divide both sides by 4.

4x/4=−5y+7/4

x=−5/4 y+ 7/4

Answer: for the first one x=−5/4 y+ 7/4

3x−2y=−12

Step 1: Add 2y to both sides.

3x−2y+2y=−12+2y

3x=2y−12

Step 2: Divide both sides by 3.

3x/3=2y−12/3

x=2/3y−4
