Answer:

25,000

Step-by-step explanation:

7 is greater than 5 so we need to round UP

Answer:

Step-by-step explanation:

x   - first number

2x   - twice the first number

twice the first number exceeds the second number by 4 so:

2x-4   -the second number

y - the third number

the second number is equal to the sum of the first and third numbers:

2x-4 = x + y

x + y = 2x - 4

  -x        -x

y = x - 4       - the third number

the sum of three numbers:

x + 2x-4 + x-4 = 4x - 8

The sum of three numbers is 12 so:

4x - 8 = 12

   +8       +8

  4x = 20

  ÷4    ÷4

   x = 5

2x-4 = 2•5 - 4 = 6

x-4 = 5 - 4 = 1

Check:

5+1 = 6

2•5 = 10,  10-4 = 6

B) Rotation, then Reflection

Answer:

This formula is related to Pythagorus theorem which states that in a right angled triangle square of hypotenuse is equal to sum of the squares of other two sides.

In other words, C²=B²+A²

Answer:

  a = h/5

Step-by-step explanation:

If you had the equation ...

  10 = 5a

and you wanted to find the value of the variable, you would divide by its coefficient:

  10/5 = (5a)/5

  2 = a

__

Here, we have replaced '10' with 'h'. The same (single) step applies: divide by the coefficient of 'a'.

  h = 5a

  h/5 = a

To put this in "a = " form, swap the sides of the equal sign:

  a = h/5

_____

Literal equations just use different symbols (h instead of 10, here). The operations are the same.

Answer:

I believe the answer would be 64w2.

Step-by-step explanation:

8 squared is 8 x 8, which equals 64, and then w squared is just w2, since we don't know what it is. Put them together, and the answer is 64w2.

Answer:

7g is correct answer

Step-by-step explanation:

4g+6g-3g

=10g-3g

=7g

hope it helped you:)

Answer:4g + 6g - 3g = 7g

Step-by-step explanation:because 4+6 is 10 so 3 less than 10 it equals 7

Answer:

$195

Step-by-step explanation:

We use the simple interest formula.

I = Prt

I = Interest

P = Principal (initial value)

r = Interest rate

t = Time (years)

P = $12,000

r = 6.5%  which we convert to a decimal by dividing by 100    6.5/100 = .065

t = 3 months    which we convert to years by dividing by 12    3/12 = 1/4 = .25

Plug in the values

I = 12000 * .065 * .25

I = $195 interest gained

Answer:

195

Step-by-step explanation:

3 month is .25 years

6.5/100 = .065

12000 x .065 x .25 = 195

Answer: Choice A) He wrote it incorrectly. He should have gotten 6.

This is because exponents of 1/2 are the same as square roots.

[tex](36)^{1/2} = \sqrt{36} = 6[/tex]

Matt probably thought it was 36 times 1/2, which may explain how he got 18.

Matt rewrote the expression incorrectly. The expression is equivalent to 6. Option A is correct.

Given that,
Matt rewrote the given expression, he got 18. [tex](36)^{1/2}[/tex] Which statement is correct is to be determined.

In mathematics, it deals with numbers of operations according to the statements.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

Since matt made a mistake in his calculation, let correct the calculation and determined what should be the matt mistake.

Simplification
[tex]= (36)^{1/2}\\= (6^2)^{1/2}\\=(6)^{2 * 1/2}\\= 6[/tex]

Thus, Matt rewrote the expression incorrectly. The expression is equivalent to 6. Option A is correct.

#SPJ2

Answer:

-9

Step-by-step explanation:

X=-9

Step-by-step

Simplifying

3 + -4x = 6x + 93

Reorder the terms:

3 + -4x = 93 + 6x

Solving

3 + -4x = 93 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

3 + -4x + -6x = 93 + 6x + -6x

Combine like terms: -4x + -6x = -10x

3 + -10x = 93 + 6x + -6x

Combine like terms: 6x + -6x = 0

3 + -10x = 93 + 0

3 + -10x = 93

Add '-3' to each side of the equation.

3 + -3 + -10x = 93 + -3

Combine like terms: 3 + -3 = 0

0 + -10x = 93 + -3

-10x = 93 + -3

Combine like terms: 93 + -3 = 90

-10x = 90

Divide each side by '-10'.

x = -9

Simplifying

x = -9

Answer:

Answer:

Step-by-step explanation:

14% of 150 mg = 0.14* 150 = 21 mg

21 mg will be eliminated  from our body in an hour

150/21 = [tex]7\frac{3}{21}[/tex]

  = 7 hours { rounding to the nearest}

Answer:

m = 6

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Simply choose 2 points and plug them into the formula to find slope m:

(1, 20)

(2, 26)

[tex]m=\frac{26-20}{2-1}[/tex]

[tex]m=\frac{6}{1}[/tex]

m = 6

Answer:

(-inf,6]

Step-by-step explanation:

Answer: Choice B)  [tex]\sqrt{14}[/tex]

We have some value m and we're squaring it to get [tex]m^2[/tex]

To undo this and isolate m, we apply the square root to both sides

[tex]m^2 = 14\\\\\sqrt{m^2} = \sqrt{14}\\\\|m| = \sqrt{14}\\\\m = \sqrt{14} \text{ or } m = -\sqrt{14}[/tex]

There are two solutions here. This is similar to how there are two solutions in something like [tex]x^2 = 25[/tex] (those two solutions being x = 5 and x = -5). Squaring any negative number leads to a positive result because

negative times negative = positive.

Answer:
