Collect like terms
x + 4x - 4 = 9 - 2 x - 6
move the terms
5x - 4 = 3 - 2x
collect like terms calculate

Triangle DEF is reflected over the y-axis, and then translated down 4 units and right 3 units. Which congruency statement descri
DerKrebs [107]
The point D transformed into S
The point E transformed into R
The point F transformed into U

The lengths are angles didn't change as result of the transformations (rotation and translation do not change the shape nor dimensions).  Then, the resulting triangle is congruent to the original triangle.

Using the same order for the letters, you might say that ΔDEF ≅ ΔSRU

ahrayia [7]

Answer:

simple interest is $6.8

Miguel pay amount to Julio at the end of 6​ months $206.8

Step-by-step explanation:

Given : Miguel Rodriguez borrowed ​$200 from his brother Julio to pay for books and tuition. He agreed to pay Julio in 6 months with simple annual interest at 6.8​%.


To Find : ​a) How much will the interest amount​ to?


​b) What amount must Miguel pay Julio at the end of 6​ months?


Solution :

Formula for simple interest :

S.I. = principal*rate*time

Where rate is in decimal

Time is in years

So, rate of interest = 6.8 % = 0.068

Time = 6 months = \frac{6}{12} = 0.5 years

Principal = $200

Thus S.I. = 200*0.068*0.5

S.I. = 6.8

Now To calculate  amount must Miguel pay Julio at the end of 6​ months

Amount = principal +Simple interest

Amount = 200+6.8 =206.8

Hence the simple interest is $6.8

And Miguel pay amount to Julio at the end of 6​ months $206.8
