Answer:

The answer to your question is: x = 7; y = 6

Step-by-step explanation:

2x+y=20 ( 1 ) Multiply by 5

6x−5y=12 ( 2 )

5 (2x+y=20) = 10x + 5y = 100

10x + 5y = 100

6x − 5y = 12 Eliminate y

16 x = 112

x = 112 / 16

x = 7

2(7) + y = 20 Substitution

14 + y = 20

y = 20 - 14

y = 6

Find the area of the irregularly-shaped hexagon below

Ber [7]

let each box length be 1

for white triangle

area = ½bh

=½(4)(2)

for orange triangle

area=½(2)(3)

for blue marked boxes

each of the box

area=l²

=(1)²

there are 16 boxes

so the total area will be 16

earnstyle [38]

Answer:

1,42 * 10 ^ -5

Step-by-step explanation:

La notación científica también se conoce como forma estándar.

Tenemos que realizar la siguiente operación y dejar el resultado en forma estándar.

Entonces;

0,00000826 * 235 × 10 ^ -7 / 0,0017 × 10 ^ -2

También;

8.26 * 10 ^ -6 * 2.35 * 10 ^ -5 / 1.7 * 10 ^ -5

= 19,411 * 10 ^ -11 / 1,7 * 10 ^ -5

= 1,42 * 10 ^ -5
