the mass of a textbook is approximately 0.00165 metric ton . how is this number written in scientific notation
DiKsa [7]

Answer:

1.65 X 10^-3 (i don't know if your teacher wants you to also add the unit at the end, but if your teacher does, then just add metric ton at the end. :-) )

Step-by-step explanation:

We want to bring the decimal point to the right of the first number, so you move the decimal point 3 times to the right, which would give you 1.65 metric ton.

So you should know that moving a decimal point to the right would make the power negative, and moving the decimal point to the left would make the power positive.

In this situation, the power would be negative, and a negative three, because you moved the decimal point 3 times to the right.

Hope this helped :-) <3

Solving a system of equation <br> x+5y=15 <br> -3x+2y=6
Colt1911 [192]

Answer:

(0,3)

y=3

x=0

Step-by-step explanation:

x+5y=15

-3x+2y=6

solve the equation

x=15-5y

-3x+2y=6

substitute the value of x into an equation

-3(15-5y)+2y=6

distribute

-45-15y+2y=6

add 15 to 2

-45-17y=6

add 45 from both sides

17y=51

divide both sides by 17

y=3

substitute the value of y into an equation

x=15-5•3

multiply 5 to 3

x=15-15

subtract

x=0

NikAS [45]

Answer:

32 ft

Step-by-step explanation:

The perimeter is basically the area of the outside of a shape. To calculate this, you would add up all the sides together and get the answer.

8 + 8 + 8 + 8=32 or you can just do 8*4 which is also 32

So, the answer is 32
