Answer:

86.1 yd^2

Step-by-step explanation:

Half of 21 is 10.5

10.5*8.2=86.1

There is no need to divide it by two as there are two triangles stuck together. You would need to multiply it by two if you did divide it by two, but the answer would be the same.

I'm having trouble solving the system of linear equations. This is the system: 5x + 6y = 50 x - 6y = -26 Can you please help me?
natita [175]

Answer:

y = 5 ; x = 4

Step-by-step explanation:

Given :

5x + 6y = 50 - - - (1)

x - 6y = -26 - - - (2)

From (2)

x = - 26 + 6y

Put - 26 + 6y for x in (1)

5(-26 + 6y) + 6y = 50

-130 + 30y + 6y = 50

-130 + 36y = 50

-130 - 50 = - 36y

-180 = - 36y

y = 180 / 36

y = 5

Put y =5 in x = - 26 + 6y

x = - 26 + 6(5)

x = - 26 + 30

x = 4

y = 5 ; x = 4

J) 20/35 equal to 4/7

K) 4/16 is equal to 1/4

So how I got these answer is to look at the denominator or bottom number they gave u and then think what times what equals that answer for example 4/16
4x 4 =16 right! so then then what is 4 divided by 4 = 1 because what u do to the top u do to the bottom
