Solve the equation below for x.
cx- 4 = 7

A. x=11/c
B. x=c/3
C. x=3/c
D. x= c/11

Answers

Answer:

a. x = 11/c

Step-by-step explanation:

cx - 4 = 7 [add 4 to both sides of the equation]

cx = 11 [divide by c to isolate x]

x = 11/c

A chemist is using 353 milliliters of a solution of acid and water. If 14.7 of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth

Answers

Answer:

The amount of Acid in a solution = 51.9 millimeters

Step-by-step explanation:

Given that the total amount of solution of acid and water = 353 milliliters

Acid percentage = 14.7%

Thus, in order to determine the amount of acid, all we need is to multiply 353 with 14.7% or 0.147.

i.e

Amount of Acid = 14.7% of 353

= 0.147 × 353

= 51.9 millimeters

Therefore, the amount of Acid in a solution = 51.9 millimeters

1. slope
2. y-intercept
3. slope intercept form

Answers

(-5, 2) ⇒ x₁ = -5, y₁ = 2

(7, -1) ⇒ x₂ = 7, y₂ = -1

Slope:

[tex]\bold{m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-2}{7+5}=\dfrac{-3}{12}=-\dfrac14}[/tex]

Slope intercept form:

y = mx + b

Plug m and (7, -1) :

-1 = -¹/₄(7) + b

-1 + ⁷/₄ = b

b = ³/₄ ← y-intercept

Therefore slope intercept form of h(x):

h(x) = -¹/₄x + ³/₄

6/a - 4/b = 1 and 9/a - 8/b = 1

Answers

Answer:

a = 3 ; b = 4

Step-by-step explanation:

Eqn.1 = [tex] \frac{6}{a} - \frac{4}{b} = 1[/tex]

Eqn.2 = [tex] \frac{9}{a} - \frac{8}{b} = 1[/tex]

Both the eqns have RHS (Right Hand Side) equal. So,

[tex] \frac{6}{a} - \frac{4}{b} = \frac{9}{a} - \frac{8}{b} [/tex]

[tex] = > \frac{6b - 4a}{ab} = \frac{9b - 8a}{ab} [/tex]

Cancelling ab from both the denominators of both the sides,

[tex] = > 6b - 4a = 9b - 8a[/tex]

[tex] = > 8a - 4a = 9b - 6b[/tex]

[tex] = > 4a = 3b[/tex]

[tex] = > a = \frac{3b}{4} [/tex]

Putting the value of a in Eqn.1,

[tex] \frac{6}{ \frac{3b}{4} } - \frac{4}{b} = 1[/tex]

[tex] = > \frac{24}{3b} - \frac{4}{b} = 1[/tex]

[tex] = > \frac{8}{b} - \frac{4}{b} = 1[/tex]

[tex] = > \frac{8 - 4}{b} = 1[/tex]

[tex] = > b = 4[/tex]

Putting the value of b in the value of a

[tex]a = \frac{3 \times 4}{4} = 3[/tex]

Solve in order of operation
Thanks

Answers

Answer:

b) 31 and c) 11

Step-by-step explanation:

IMPORTANT: Order of operations is PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/SUbtraction).

B) Solve inside the parentheses first.

1. 2^3 - 6 = (2*2*2) - 6 = 2.

2. Now the equation looks like 3 + 7 (2)^2, Next we need to do exponents.

3. 2 to the power of 2 is 4, leaving you with 3+7(4)

4. Now multiply 7*4, which is 28 then add 3 to it.

So B) would ultimately be 31.

C) As we did in equation B, we start with parentheses.

1. (6/3) we can just simplify this to 2, so those parentheses are out of the way.

2. Now we need to do exponents, (-3)^2. This is the same as -3 * -3. This would equal 9.

3. So far the equation looks like 4 + 9 - 2 / 2.

4. Next would be to solve any multiplication/division problems we have. We can see from step 3 that we have a -2 divided by a positive 2. This would give us -1.

5. Now the equation looks like 4 + 9 - 2. Now you can just working from left to right.

So C) would solve to 11

Tammy figured her math exam would be difficult unless she put in at
least 15 hours of study time to prepare. She studied 2½ hours on
Monday, 3 hours on Tuesday, 4¾ hours on Wednesday, and 4 ½
hours on Thursday. Did she study for at least 15 hours? Explain.

Answers

Answer: No, she did not study for at least 15 hours.

=======================================================

Explanation:

Fractions are often a pain, so I find it easier to convert to decimal form whenever possible.

1/2 = 0.5

3/4 = 0.75

which lead to,

2 & 1/2 = 2 + 1/2 = 2 + 0.5 = 2.5

4 & 3/4 = 4 + 3/4 = 4 + 0.75 = 4.75

4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5

-----------------------------

We can then rephrase the problem like so:

"She studied 2.5 hours on Monday, 3 hours on Tuesday, 4.75 hours on Wednesday, and 4.5 hours on Thursday"

Add up those decimal values to get:

2.5 + 3 + 4.75 + 4.5 = 14.75

In total, Tammy studied for 14.75 hours, which is equivalent to 14 & 3/4 hours.

This result is smaller than 15, so she did not study for at least 15 hours.

Note: "at least 15" is the same as saying "15 or more".

Answer:

2xy

Step-by-step explanation:

Here, we want to obtain the number with the smallest square

To get this, we simply find the nearest number square which is 2

The nearest x squared which is x (to get x^4)

The nearest y squared which is y (to get y^2)

Thus, the smallest number so we get a square will be; 2xy

What is the solution to the following equation? x2 + 3x + 4 = 0

Answers

Answer:

[tex]x=\dfrac{-3\pm \sqrt7i}{2}[/tex]

Step-by-step explanation:

The given equation is [tex]x^{2}+3x+4=0[/tex].

We need to find the solution of the above equation.

The solution of an equation [tex]ax^2+bx+c=0[/tex] is :

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

We have, a = 1, b = 3 and c = 4

[tex]x=\dfrac{-3+ \sqrt{(3)^2-4(1)(4)} }{2}, \dfrac{-3- \sqrt{(3)^2-4(1)(4)} }{2}\\\\=\dfrac{-3+\sqrt{9-16}}{2}, \dfrac{-3-\sqrt{9-16}}{2}\\\\=\dfrac{-3\pm \sqrt7i}{2}[/tex]

So, the solution of the given equation is [tex]\dfrac{-3\pm \sqrt7i}{2}[/tex].
