Blababa [14]
<h3>Answer:</h3>

1165.83 kg

The total mass is the product of volume of one brick, the number of bricks, and the density. For this problem, it is convenient to use dimensions in meters.

(0.051\,m)(0.102\,m)(0.203\,m)(600)\dfrac{1840\,kg}{m^3}=(0.6336036\,m^3)\dfrac{1840\,kg}{m^3}\\\\=1165.83\,kg

Find the solutions of the systems -6x-2y=8 and 7x-2y=-5
Daniel [21]

Answer:

y=4  

x= 3/7

Step-by-step explanation:

2y=8

Divide both sides by 2

2y÷2=8÷2

A.) y=4

Substitute 4 for y

7x−2y=−5

7x+(−2)(4)=−5

Simplify both sides of the equation.

7x−8=−5

Add 8 to both sides

7x−8+8=−5+8

7x=3

Divide both sides by 7

7x÷7= 3÷7

x= <u>3</u>

    7
