How does the value of a decimal changes as you move to the left or the right in a place value chart

1 answer:

7 0

If you move it to the left the number would increase so for example you had 2.3 and you move it to the left then it would be 23, so if you times it by tenth or hundredth then it would go to the left but if you divide then it would go down so moving to the right would get you 0.23

Answer:

Below

Step-by-step explanation:

● x-20 = y+20 (1)

● 2(y-22) = x+22 (2)

This is a system of simulataneous equations

Let's simplify the expressions first

● x -20 = y + 20 (1)

Add 20 to both sides

● x -20 + 20 = y+20 +20

● x = y + 40 (1)

● 2(y-22) = x+22 (2)

● 2y - 44 = x +22

Substrat 22 from both sides

● 2y-44-22 = x+22-22

● 2y -66 = x (2)

This is the new system:

● x = y+40 (1)

● x = 2y-66 (2)

Substract (2) from (1)

● x-x = y+40-(2y-66)

● y+40-2y+66 = 0

● -y +106 = 0

● y = 106

Replace y with 106 in (1)

● x = y +40

● x = 106+40

● x = 146

So the solutions are (146,106)

D is most likely right. Basically, I would turn them into decimals and divide using a graphing calculator.

Each wheel of gias bicycle is 24 inches in diameter gia rides her bike 1,884 feet to the nearest whole number how many times doe

cupoosta [38]

The wheel turned a total of 300 times in 1,884 feet.

Step-by-step explanation:

Step 1:

The wheels of the bicycle have a diameter of 24 inches. So the radius of the wheels is 12 inches.

To determine how many times the wheel turns we divide the distance traveled by the circumference of the wheels.

The circumference of a circle is given by multiplying 2π with the radius.

The circumference of the wheel $= 2(3.1415)(12) = 75.396.$

The circumference of the wheel is 75.396 inches.

Step 2:

Gia traveled 1,884 feet, we need to convert this into inches.

If 1 feet = 12 inches, 1,884 feet = 22,608 inches.

The number of times the wheel turned $\frac{22,608}{75.396} = 299.8567.$

Rounding this off, we get that the wheel turned a total of 300 times in 1,884 feet.
