: 14x² +(-21x)+4x+(-6)

answer: 14x²-17x-6

Answer: B

Step-by-step explanation:

The simplified equation that is equivalent to the given equation is 16x - 5 = -47. The correct answer is option B.

The equation is given as follows:

15x - 5 + x = -47

A solution to an equation, as we know, is a variable value that, when substituted into the equation, provides a true claim.

To simplify the equation 15x - 5 + x = -47, we can combine the like terms on the left side of the equation.

Combining the terms with 'x', we have:

15x + x - 5 = -47

16x - 5 = -47

Therefore, the simplified equation that is equivalent to the given equation is 16x - 5 = -47.

Answer Part A: ^

The equation 3x =y models the relationship between jellyfish, and sea turtles such that the ratio of their numbers remain constant.

Ratio is the relationship between two numbers given by a quotient

If the ratio of two numbers x and y is x/y then the fraction x/y gives that what parts x is of y .

Given that there are 4 sea turtle and 12 jellyfish in the sea when Alex counted the number.

Ratio of number of sea turtle to number of jellyfish = 4/12 = 1/3

Let at any time the number of sea turtles be x and number of jellyfish be y

Then ratio of number of sea turtles to jellyfish = x / y

Given that this ratio remained constant during the remainder of his dive,

∴ x/y = 1/3

Cross multiply

⇒ 3x = y

The equation that models the relationship between jellyfish, and sea turtles is 3x =y

Answer:

The percent change is approximately 66%.

Step-by-step explanation:

200 is one-third of 600. In math involving percentages, division comes into play in some ways. Divide 600 by 3, and you get 200. 33% is a third of 100% in mathematics, meaning that 200 is one-third, or 33%, of 600.

Answer:

the answer is 66

Step-by-step explanation:

i just did the test

I have no idea whether those numbers are correct, and I'm not gonna bother looking them up.

But you gave us a speed and a distance, and you asked for a time.

We can just go ahead and use the formula:  Time = (distance) / (speed) .

IF your numbers are true, then

Time = (distance) / (speed)

Time = (3.55 x 10⁹ mi) / (1.25 x 10⁷ mi/min)

Time =  (3.55 x 10⁹ / 1.25 x 10⁷) minutes

Time =  2.84 x 10² minutes

Time = 284 minutes

Time = 4 hours 44 minutes

Step-by-step explanation:

Step-by-step explanation:

5x + 2 = 50 - x (vertically opp angle)

5x + x = 50 - 2

6x = 48

x = 8

if you wanna check it,

5x + 2 = 50 - x

5(8) + 2 = 50 - 8

Answer:

y = 1/2x -.5

Step-by-step explanation:

We know that is the line is parallel to the equation then the slopes are going to be the same we just have to find the a different y-intercept.

It's a simple as this just plug the points into the equation you have like this.

(-7,-4) (PLUG IN)

-4 = 1/2(-7) +b (I do plus be so we can get another y intercept)

-4 = -3.5 + b (add 3.5 on each side)

-.5 = b

the equation parallel to the first one is...

y = 1/2x -.5

Answer:

b

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

First we find the diameter ((h)) of the rectangle on the floor using the Pythagorean theorem.

So we have :

[tex] {h}^{2} = {a}^{2} + {b}^{2} [/tex]

[tex] {h}^{2} = 64 + 9 [/tex]

[tex] {h}^{2} = 73 [/tex]

[tex]h = \sqrt{73} [/tex]

_________________________________

Step (2)

Now we another using of Pythagorean theorem for finding d :

[tex] {d}^{2} = {h}^{2} + {c}^{2} [/tex]

[tex] {d}^{2} = 73 + 16 [/tex]

[tex] {d}^{2} = 89 [/tex]

[tex]d = \sqrt{89} [/tex]

[tex]d = 9.4[/tex]

Answer:

∠L = 54°

Step-by-step explanation:

5x + 2x + 3x = 180 (all angles in a triangle add up to 180)

10x = 180

x = 18°

∠L = 3x

sub x = 18

3(18) = 54

∠L = 54°

Ok, noticed that the bottles are not properly given a unit according to the question.

let us assume the units are in centiliters that is cl

Every morning the bottle of water has 16.9cl

the bottle of orange juice has 15.2cl

therefore if Jakie does this drinking continuously for 7 days she will be drinking

bottle of water has 16.9cl*7= 118.3cl

bottle of orange juice has 15.2cl*7=106.4cl

total=118.3+106.4

total is 224.7cl

Answer:

4 packs of medium cups and 6 packs of large cups

Step-by-step explanation:

1.80x + 2.40y = 21.60

1.80(4) + 2.40(6) = 21.60

7.2 + 14.4 = 21.60

21.60 = 21.60

Answer:

Ivy bought 4 packs of medium cups, and 6 packs of large cups.

Step-by-step explanation:

To solve this problem, we will have to use a system of equations. Our first equation will represent the cups, and our second equation the costs.

Let [tex]m[/tex] equal medium cups.

Let [tex]l[/tex] equal large cups.

[tex]m+l=10[/tex]

[tex]1.80m+2.40l=21.60[/tex]

Let's use substitution to solve this system.

Subtract [tex]l[/tex] from both sides of the first equation:

[tex]m=10-l[/tex]

Let's substitute [tex]10-l[/tex] into the second equation for [tex]m[/tex]:

[tex]1.80(10-l)+2.40l=21.60[/tex]

Distribute [tex]1.80[/tex] into [tex](10-l)[/tex]:

[tex]18-1.80l+2.40l=21.60[/tex]

Combine like terms:

[tex]18+0.6l=21.60[/tex]

Subtract [tex]18[/tex] from both sides of the equation:

[tex]-0.6l=3.60[/tex]

Divide by the coefficient of [tex]l[/tex], which is [tex]0.6[/tex]:

[tex]l=6[/tex]

Ivy bought 6 packs of large cups.

_

Let's substitute [tex]6[/tex] into the first equation to find the number of medium cup packs:

[tex]m+6=10[/tex]

Subtract [tex]6[/tex] from both sides of the equation:

[tex]m=4[/tex]

Ivy bought 4 packs of medium cups.

_

We can check our work 2 ways; by substituting our solved values into the initial equations.

1st Equation Check:

[tex](4)+(6)=10[/tex]

[tex]10=10[/tex]

2nd Equation Check:

[tex]1.80(4)+2.40(6)=21.60[/tex]

[tex]7.2+14.4=21.60[/tex]

[tex]21.60=21.60[/tex]

Our answers are correct!

Answer:

Undefined.

Step-by-step explanation:

When using the formula y2-y1/x2-x1, the result comes out as -4/0. Any number over a 0 is undefined.

Easy buddy....

[tex] - 6 \times ({ - 2})^{ - 3} \times ({4})^{2} = [/tex]

[tex] - 6 \times ({ - \frac{1}{2} })^{3} \times 16 = \\ [/tex]

[tex] - 6 \times ( - \frac{1}{8}) \times 16 = \\ [/tex]

16 simplifies to by 8 and equals 2

[tex] - 6 \times ( - 2) = 12[/tex]
