What is \bf{\bigg(\dfrac{2}{5}\bigg)^2?

\Large\maltese\underline{\textsf{This problem has been solved!}}

When we have a fraction that is raised to a specific power, we raise both the numerator and the denominator to that power.

\bf{\dfrac{2^2}{5^2}}=\dfrac{4}{25}

\rule{300}{1.7}

Question 2 (5 points) Saved
ratelena [41]

Answer:

(1, -1/2)

Step-by-step explanation:

7x - 2y = 8

5x + 2y = 4

I would use elimination to get rid of y

Add the two equations together

7x - 2y = 8

5x + 2y = 4

-------------------------

12x = 12

Divide each side by 12

x =1

Now find y

5x+2y = 4

5*1 +2y =4

Subtract 5 from each side

5+2y -5 = 4-5

2y = -1

Divide by 2

2y/2 =-1/2

y = -1/2

The product of 2 and a number x is 3/4 . What is the value of x? x=5/4 x=3/8 x=1 1/4 x=3/2
I am Lyosha [343]

Ok,

2 * X = 3/4

divide by 2 on both sides...

X = 3/4 * 2

3/4/2 = 1.5/4 = 3/8

So X = 3/8!

What is the value of side EC ?
zloy xaker [14]

Answer:

EC = 28'

Step-by-step explanation:

Since ∆KAR ~ ∆ENC, therefore, their corresponding side lengths will be proportional to each other.

By implication, we have:

EN/KA = EC/KR

EN = 96'

KA = 24'

EC = ?

KR = 7'

Thus:

96/24 = EC/7

Cross multiply

EC*24 = 7*96

EC*24 = 672

Divide both sides by 24

EC = 672/24

EC = 28'
