Step-by-step explanation:

Answer:

3 x 10 to the 11th

Step-by-step explanation:

move the decimal to the right, keeping it positive, 11 times to make it 0.3

Answer:

The exponent represents the number of places the decimal moves.

The decimal moves to the right.

The exponent is negative.

Step-by-step explanation:

Given:

Newton has 10 more dimes than nickels.

He has  twice the number of quarters than nickels.

Total amount he has = $6.20.

To find:

The number of each coin.

Solution:

Let the number of nickels be x.

Newton has 10 more dimes than nickels.

Dimes = x+10

He has  twice the number of quarters than nickels.

Quarters = 2x

We know that, 1 nickel = $0.05, 1 dime = $0.10 and 1 quarter = $0.25.

Total amount he has is $6.20.

[tex]x\times 0.05+(x+10)\times 0.10+2x\times 0.25=6.20[/tex]

[tex]0.05x+0.10x+1+0.50x=6.20[/tex]

[tex]0.65x=6.20-1[/tex]

[tex]0.65x=5.20[/tex]

Divide both sides by 0.65.

[tex]x=\dfrac{5.20}{0.65}[/tex]

[tex]x=8[/tex]

Now,

Number of nickels = 8

Number of dimes = 8 + 10 = 18

Number of quarters = 2(8) = 16

Therefore, the number of nickels, dimes and quarters are 8, 18 and 16 respectively.

The equation for the problem is [tex]0.25x[/tex] ≤ [tex]3.65[/tex]

Hope it helps!

You can make the maximum number of copies would be 14.6 which is determined by the inequality 0.25x ≤ 3.65 where x represents the number of copies.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

You have at most $3.65 to make copies for a school project. Each copy costs $0.25 which is given in the question.

As per the given condition, the required inequality would be:

⇒ 0.25x ≤ 3.65

Here x represents the number of copies

⇒ 0.25x ≤ 3.65

Divided by 0.25 both sides of the inequality, and we get

⇒ x ≤ 3.65/0.25

⇒ x ≤ 14.6

Therefore, you can make the maximum number of copies would be 14.6.

Answer:

Step-by-step explanation:

5x + 3 > 48

5x > 48 - 3

5x > 45

x > 45/ 5

x > 9

Answer:

x = 9

Step-by-step explanation:

5x + 3 > 48

Subtract 3 to both sides

5x > 45

Divide by 5 to both sides

x = 9

To check if the answer is correct, you can always plug in 9 instead of x and solve the equation.

Answer:26 feet, Oliver will have to travel 26 feet deep.

Step-by-step explanation:Okay so if you draw a line graph going vertical and you number it 1-32 ( this is if you have to show work ) a is a 11 feet deeper and b is 23 feet deeper

Answer:

x=28 y=11 z=1

Step-by-step explanation:

plug in 1 for z in x+2z=30 to get x+2(1)=30. Then you should get x+2=30 which is x=28.

Then, plug 1 in for the second equation of y+z=12 so you get y+1=12. Then you should get y=11.

Hope this helps pls if it help u mark me BRAINLIST pls thank u.

Answer:

12

Step-by-step explanation:

no

Answer:

let the first no. be x

then the second no. = x - 6

their sum is 48

therefore,

[tex] = > x + (x - 6) = 48 \\ = > 2x = 48 + 6 \\ = > 2x = 54 \\ = > x = \frac{54}{2} \\ = > x = 27[/tex]

The value of first no. = x = 27

The value of second no. = x - 6 = 27 - 6

= 21

Answer:

X equals 5

Answer:

I think X=3

Step-by-step explanation:

When adding fractions you have to find a common  denominator, the easiest way is to use the other number for it. So with [tex]\frac{x}{2}[/tex] you would multiply the top and bottom by 6, and with [tex]\frac{x}{6}[/tex] you would multiply both the top and bottom by 2. You should then have [tex]\frac{6x}{12}[/tex]+[tex]\frac{2x}{12}[/tex]. You add the tops together which will leave you with 8x and the bottom stays the same. Then you multiply the the 2 by the 12, and when doing this the 12 will cancel out. leaving you with 8x= 24. Finally you divide 24 by 8 and X is 3.
