5-2(x+5)=3x-15 solve for X

Answers

Answer 1

Answer:

x= 2

Step-by-step explanation:

5 -2(x +5)= 3x -15

Expand:

5 -2x -2(5)= 3x -15

5 -2x -10= 3x -15

Simplify:

-2x -5= 3x -15

Bring x terms to 1 side, constant to the other:

3x +2x= 15 -5

5x= 10

Divide both sides by 5:

x= 10 ÷5

x= 2

Answer 2

Answer:

Step-by-step explanation:

x=2

Answer:

Such triangles do not exist.

Step-by-step explanation:

There is some mistake in your question.

We know:

In any triangle with sides a, b and c:

a + b > c

a + c > b

b + c > a

In your question the triangle ABC has:

a = 5, b = 10, c = 15

then

5 + 10 = 15 not > 15.

a + b = c not > c.

In my opinion, the question makes no mathematical sense.

Nevertheless, the moderator asked me to correct my answer.

If two triangles are similar, then corresponding sides are in proportion.

[tex]\dfrac{10}{5}=\dfrac{20}{10}=\dfrac{x}{15}\\\\2=2=\dfrac{x}{15}\\\\\dfrac{x}{15}=2\Rightarrow x=30[/tex]

Using ordered pair (900,1150)
Slope= 4/3

Solve for the y intercept

Answers

Answer:

the y intercept is -50

Step-by-step explanation:

in y=mx+b, m is the slope and b is the y intercept. We are given the point (900,1150) and a slope of 4/3

we can susbstitute 4/3 into the equation.

y=4/3x+b

since the line will go through the point (900,1150), we can plug it into the equation.

1150=4/3(900)+b

1150=1200+b

-50=b

we are left with the y intercept (b) being -50. As a point, it's (0,-50)

Hope this helps!

Find a polynomial, which if substituted for M will make the equation an identity: (4c^4–7c^2+6)–M=0

Answers

Answer:
-3c^2+6
Step-by-step explanation:
The equation will be identity (0=0) when M is equal to the contents of the parentheses. That polynomial can be used directly, or it can be simplified by combing the c^2 terms.

The contents of parentheses simplify as follows: (4c^2 - 7c^2 +6)=(c^2(4 -7)+6)=(-3c^2 +6)

Answer:

It is -3c^2+6.

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.

On any given week, if Salesman B earns $1,020, how many sales did he have for the week?
sales

Answers

If we take the paycheck amount of $1020 and subtract it by the weekly salary of $300.

$1020 - $300 = $720

We get $720 in sale commissions. So to get the number of sales, you divide the $720 by the $40 per sale commission.

$720/$40 = 18

Therefore, the sales Salesman B has for the week is 18.

he had 18 sales for the week

Megabyte - 0, 25, 50, 75, 100.

Seconds - 1, 2, 3, 4.

Number 3; Part B:

The problem says "A computer downloads songs at a ratio of 50 megabytes in 2 seconds." So, (ratio = 50:2 )...

50:2 = 25:1

-If your confused about part a or b, this is how I did pt. A...

First you have to find the pattern in the number line.

I can tell that the pattern is ×25.

-For part b, I divided the ratio (50:2) by 2.
