Answer:

-16 =x

Step-by-step explanation:

−6 = 3/8x

Multiply each side of the equation by 8/3 to isolate x

-6 *8/3 = 8/3* 3/8 x

-48/3 = x

-16 =x

Answer:

Step-by-step explanation:

-6=3/8x

To make this easier to visualize:

3/8= 0.375

-6=.375x

Divide both sides by .375

The right side cancels.

-6/.375=-16

So x=-16

Answer: A

Step-by-step explanation:

m(x) = x² + 2  

n(x) = 5x + 9

(m*n)(x) = (x² + 3)(5x + 9)

            = x²(5x + 9) + 3(5x + 9)

            = 5x³ + 9x² +  15x + 27

Answer:

[tex]5x^3 +9x^2 +15x+27[/tex]

Step-by-step explanation:

If m(x) = x2 + 3 and n(x) = 5x + 9,

(mn)(x) is (m times n)(x)= m(x) times n(x)

m(x)  * n(x)

Plug in m(x) and n(x). then multiply it

m(x)  * n(x)

(x^2 + 3)(5x+9)

Apply FOIL method to multiply it

x^2 * 5x = 5x^3

x^2 * 9 = 9x^2

3*5x= 15x

3*9 = 27

[tex]5x^3 +9x^2 +15x+27[/tex]

Statement 1: AM is the midpoint of AB

Reason 1: Given

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

Statement 2: AM+MB = AB

Reason 2: Segment Addition Postulate

Further explanation: Basically this idea is where you can break up the line segment into smaller pieces, or glue smaller segments to form a larger segment.

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

Statement 3: AM = MB

Reason 3: Definition of midpoint

Further explanation: The midpoint cuts a line segment in half. The two smaller pieces AM and MB are congruent (ie equal in length)

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

Statement 4: AM + AM = AB

Reason 4: Substitution

Further explanation: We replace the MB in statement 2 with AM. This replacement is possible because of the equation AM = MB in statement 3.

This concludes the proof.

3c(c+3)-4(c+3)=3c^2+9c-4c-12=3c^2+5c-12

The expression in complete factored form is (3c - 4)(c + 3)

A complete factored form is a form of expressing a complex polynomial expression as the products of factors of the polynomial. If we equate the complete factored expression with zero, we get the solutions of the polynomial expression.

The expression given is [tex]3c(c + 3) - 4(c + 3)[/tex]

Expanding the given expression  [tex]3c^{2} + 9c - 4c - 12[/tex]

= [tex]3c^{2} + 5c - 12[/tex]

= [tex]3c^{2} + 9c - 4c - 12[/tex]

= [tex]3c(c + 3) - 4(c + 3)[/tex]

= [tex](3c - 4)(c + 3)[/tex]

Thus the expression in complete factored form is (3c - 4)(c + 3)

Answer:

4 bags and 6 apples

or

4.75 bags of apples

Step-by-step explanation:

First, take 38 divided by 8. You get 4.75. That means 4 bags have been filled up.

Next take 8 times 4. you get 32. then take 38-32 and you get 6.

That means there is 4 bags of apples and 6 left over. You could also say 4.75 bags are filled.

Answer:

The answer is A

Step-by-step explanation:

When two parallel lines are crossed by another line the angle of 1 will be equal to 4, 5, and 8. The angle 2 will be equal to 3, 6, and 7. Since a straight line has a degree of 180, the subtracted degree of 180-140=40 which would mean 2=40 which 2=6 so 6=40.

Answer:

40°, A

Step-by-step explanation:

What are we going to do to figure out measure 6?

First of all, we know that measure 5 and measure 6 are equal to 180 degrees.

Second of all, we know that measure 1 and measure five are corresponding angles, which means they are congruent. If measure one is 140 degrees, measure 5 would also be 140 degrees.

So we know that measure 5 and measure 6 are equal to 180 degrees. We can now make an equation...

Let x = measure 6

Answer:

The exact answer is 27 * pi

or the approximate answer is 27 * 3.14 = 84.78

Step-by-step explanation:

First step is to find the area of the circle

A = pi * r^2

A = pi * 6^2

A = 36* pi

We are missing 90  degrees of the circle  or 90 out of 360.

That means we keep 360 - 90 = 270  or 270/360

The fraction we are keeping simplifies to 3/4  (divide top and bottom by 90)

Multiply the area by the fraction that we kept.

36 pi * 3/4 = 27 * pi

The exact answer is 27 * pi

or the approximate answer is 27 * 3.14 = 84.78

Step-by-step explanation:

A cube has a volume of 15.625 m^3 of hay

We want to find the length of one side

V= s^3 where s is the length of one side

15.625 = s^3

Take the cube root of each side

15.625 ^ (1/3) = s^3 ^(1/3)

15.625 ^ (1/3) = s

2.5 = s

The length of each side is 2.5 m

Answer:

I is the √-1 so it would be √-2 as your answer

Step-by-step explanation:

If the value of i = [tex]\sqrt{1}[/tex] then value of i² = 1.

When we raise numbers to powers they  are either called surds when we raise powers which are greater than zero but less than 1 in fraction from.

We call indices when we raise powers to which are greater than 1.

Indices make the base larger after simplification and surds make the bases smaller after simplification.

According to the given question i = [tex]\sqrt{1}[/tex].

∴ The value of i² is i×i = [tex]\sqrt{1}[/tex] × [tex]\sqrt{1}[/tex] = [tex]1^\frac{1}{2}[/tex] × [tex]1^\frac{1}{2}[/tex] = [tex]1^[\frac{1}{2}+\frac{1}{2}][/tex] = 1¹ = 1.

Answer:

A. y=2x-3

Step-by-step explanation:

Since we have it in slope intercept form y=mx+b.  B is our y intercet which we know is -3. Next we can find the slope which rise over run.  This gives up 2 and our answer.

Answer:

It should be 12 because:

31.8 - 22.2 = 9.6

9.6 ÷ 0.8 = 12

For this, simply set up a proportion. If 12 oz. costs $3.60, then this means $3.60 per oz, or [tex]\frac{3.6}{12}[/tex]. Now letś make a proportion for 20 oz. Itś asking for how much it would cost if the unit price was the same, which means that the two should have a similar ratio. Because we don´t know how much it costs yet, this means x dollars for a 20 oz. bottle, or [tex]\frac{x}{20}[/tex]. I´ve already mentioned that they two are proportional, so write [tex]\frac{3.6}{12} = \frac{x}{20}[/tex].

To solve, cross multiply.

⇒[tex]12*x=3.6*20[/tex]

⇒[tex]12x=72[/tex]

Isolate variable x.

⇒[tex]\frac{12x}{12} = \frac{72}{12}[/tex]

⇒ x = 6: $6.00 for 20 ounces of soda.

Checking your work:

3.6/12 = 0.3

6/20 = 0.3

This means that theyŕe proportional, and that your answer is correct. Hope this was helpful.

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

Explanation:

We have two beakers, each of which we don't know how much is inside. Let's call this x and y

x = amount of liquid in the first beaker (water+acid)

y = amount of liquid in the second beaker (water+acid)

We're told that the beakers have a 50% solution and a 70% solution of acid. This means that the first beaker has 0.5*x liters of pure acid, and the second beaker has 0.7*y liters of pure acid. In total, there is 0.5x+0.7y liters of pure acid when we combine the two beakers. This is out of x+y = 60 liters total, which we can solve for y to get y = 60-x. We will use y = 60-x later on when it comes to the substitution step

We can divide the total amount of pure acid (0.5x+0.7y liters) over the total amount of solution (x+y = 60) to get the following

(0.5x+0.7y)/(x+y) = (0.5x+0.7y)/60

We want this to be equal to 0.6 because Gabe wants a 60% solution when everything is said and done, so

(0.5x+0.7y)/60 = 0.60

0.5x+0.7y = 0.60*60 .... multiply both sides by 60

0.5x+0.7y = 36

0.5x+0.7( y ) = 36

0.5x+0.7(60-x) = 36 ........ replace y with 60-x (substitution step)

0.5x+0.7(60)+0.7(-x) = 36 .... distribute

0.5x+42-0.7x = 36

-0.2x+42 = 36

-0.2x = 36-42 .... subtract 42 from both sides

-0.2x = -6

x = -6/(-0.2) .... divide both sides by -0.2

x = 30

He needs 30 liters of the 50% solution

Use this x value to find y

y = 60-x

y = 60-30

y = 30

So he needs 30 liters of the 70% solution

Answer:

7/8

Step-by-step explanation:

Step 1: Change the denominators so that they are the same for both fractions

7/8 x 15 = 105/120

13/15 x 8 = 104/120

Step 2: Compare

104/120 < 105/120 = 13/15 < 7/8

The fraction 7/8 is bigger than 13/15.

To determine which fraction is bigger between 7/8 and 13/15, we need to find a common denominator. The least common multiple of 8 and 15 is 120. Now, we can convert both fractions to have the same denominator:

7/8 = 105/120

13/15 = 104/120

Since 105/120 is larger than 104/120, the fraction 7/8 is bigger than 13/15.

Answer:

(x, y ) = (5, 4 )

Step-by-step explanation:

given the 2 equations

3x - 2y = 7 → (1)

- 3x + 5y = 5 → (2)

adding the 2 equations term by term will eliminate x

(3x - 3x) + (- 2y + 5y ) = (7 + 5 )

0 + 3y = 12

3y = 12 ( divide both sides by 3 )

y = 4

substitute y = 4 in either of the 2 equations and solve for x

(1 ) : 3x - 8 = 7 ( add 8 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

solution is (5 , 4 )
