Answer:

CED = 117

Step-by-step explanation:

21x +21 = 7x +49

21x - 7x = 49 - 21

14x = 28

x = 28/14

x = 2

7x + 49

=7(2) + 49

=14 + 49

=63

180 -63 = 117

CED= 117

Answer:

7x+49=21x+21 ( vertically opposite side are equal )

49-21=21x-7x

28=14x

x=28÷14

x=2

hence, putting the value of x

7x+49=7×2+49

=63

21x+21=21×2+21

=63

Combine like terms to create an equivalent expression. Make sure to simplify coefficients and constants as well. 2\left(\dfrac{1
blsea [12.9K]

Answer:

\dfrac{2m}{5}-\dfrac{1}{5} \:or\: \dfrac{2m-1}{5}

Step-by-step explanation:

Given the expression

2\left(\dfrac{1}{5}m-\dfrac{2}{5}\right)+\dfrac35

STEP 1: Eliminate the brackets

2\left(\dfrac{1}{5}m-\dfrac{2}{5}\right)+\dfrac35=\dfrac{2}{5}m-\dfrac{4}{5}\right+\dfrac35

STEP 2: Simplify the constants

\dfrac{2m}{5}+\dfrac35-\dfrac{4}{5}=\dfrac{2m}{5}+\dfrac{3-4}{5}\\=\dfrac{2m}{5}-\dfrac{1}{5}\\=\dfrac{2m-1}{5}

Owen made a down payment of $1,600 on a car that was 20% of the total price what was the total price of the car
gtnhenbr [62]
Hey there!

We can set up an equation. Since 20% is said as twenty percent, we can conclude that it says "per-cent", which means "per hundred", like century is a hundred years. That way, we can say that 20% is also written as a decimal of twenty hundredths, because it's per hundred. Thus, we're saying that his down payment, 1,600, is (this is keywording for equals) 20% of (keyword for multiplication) the total price (x). That gives us:

1,600 = .20x

Divide both sides by .20

x = 8,000

Therefore, the cost of the car was 8,000 dollars.

Hope this helps!
