Answer:

x = 20

Step-by-step explanation:

x - 8 = 12 Add 8 to both sides

x -8 + 8 = 12 + 8 Add -8 and 8; add 12 and 8

x = 20

Answer: x=20

Step-by-step explanation: Just do 12 + 8, addition is the opposite of subtraction so if you need to find the answer just do it backwards, 12 + 8 = 20. Hope this helps

Sydney is playing a game on a map with a marked grid. To start, she places a game piece at (1, 4). She moves 3 units east and 2

Anastasy [175]

Answer:

(7, 8)

Step-by-step explanation:

If Sidney places each piece 3 units east and 2 units north of the last one, we can figure out which coordinate comes first by subtracting the position of the second piece (S) by the position of the first piece (F):

$S - F = (4,6) - (1,4) = (3,2)$

We can conclude that coordinates are in the (East, North) format.

Therefore, the location of the third piece (T) is:

$T = S(E,N) +(3,2)= (4,6)+(3,2)\\T = (7,8)$

ANSWER

$x = 1.6$

EXPLANATION

The given equation is:

$- 0.5x - 2 = 2x - 1 - 6$

Group similar terms to obtain:

$- 0.5x - 2x = - 5 - 1 + 2$

Simplify similar terms,

$- 2.5x = - 4$

Divide both sides by -2.5

$x = \frac{ - 4}{ - 2.5}$

$x = 1.6$

Let C, S and H be the diameters of cell, sand and hair

Diameter of a cell: $C=1 \cdot 10^{-5}m$

Diameter of a grain of sand: $S=2 \cdot10^{-4}m$

Part A:

$H=0.000025=2.5 \cdot 10^{-5}$ meters, because it takes 5 movements right of the decimal dot, until there is only one digit to its left.

Part B:

we are comparing $S=2 \cdot10^{-4} m$ to $C=1 \cdot10^{-5} m$ ,

$\frac{S}{C}= \frac{2 \cdot 10^{-4}}{1 \cdot 10^{-5}}=\frac{20 \cdot 10^{-5}}{1 \cdot 10^{-5}}=20$

thus S is 20 times larger than C

Part C

$1m=1 \cdot10^9nm$

thus,

$H=2.5 \cdot 10^{-5}m=2.5 \cdot 10^{-5} \cdot 1 \cdot 10^9nm=2.5 \cdot 10^{-5+9}=2.5\cdot10^4nm$

Part D.

$1m=1\cdot 10^9nm\\\\1nm=\displaystyle{ \frac{1m}{10^9}=1\cdot 10^{-9}m}$

thus 300 nm are written in meters as follows:

$300nm= 300\cdot 1\cdot 10^{-9}m=3\cdot 10^2 \cdot 10^{-9}m=3\cdot 10^{-7}m$
