Find the value of w in the pentagon below if the perimeter is 105 meters.
(3 + 2w) m
(3 + 2w) m
(3 + 2w) m
(3 + 2w) m
(3 + 2w) m

Answers

Answer 1

Answer: 9 (with a margin of: 0)

Step-by-step explanation:

Times everything by 5

That gives you 15 + 10w = 105.

Subtract 15 from both sides

Divide by 10 to get w by itself

Then you solve

Answers that are mixed numbers must be entered as an improper fraction or a decimal.

Answers

Answer:

x = -15/2 or -7.5

Step-by-step explanation:

6x - 4(x - 9) = 2(3 - x)

6x - 4x + 36 = 6 - 2x

2x + 36 = 6 - 2x

4x + 36 = 6

4x = -30

x = -30/4

x = -15/2

Check:

6(-7.5) + -4(-7.5 - 9) = 2(3 + 7.5)

-45 + 66 = 2(10.5)

21 = 21

Answer:

[tex]-\frac{15}{2}[/tex]

Step-by-step explanation:

6x-4(x-9)=2(3-x)

6x-4x+36=6-2x (expansion)

2x+36=6-2x (collecting like terms)

2x+2x=6-36

Elyse wants to buy a new softball glove that costs $46.50. She has $15 and plans to save $5.25 each week. How many weeks will it take her to save the money?
write an equation using x as the variable

plz hurry im being timed

Answers

Answer:

$46.50 = $15+ $5.25x

it will take her 6 weeks

Step-by-step explanation:

she has $15, so that stays the same and the amount she saves each week is multiplied by the number of weeks. then solve the equation to find the value of x or the number of weeks and get 6 weeks

Answer:

6 weeks

Step-by-step explanation:

5.25 times 6 equals 31.5 plus 15 equals 46.50

The restaurant bill for Annette is $55.82.

She adds an 18% tip for the waiter.

What is the total cost of Annette's meal rounded to the nearest cent?

pls answer seriously, I'm failing this class its so hard for me :(

Answers

first we have to find 18% of $55.82, which we can do by using the equation 55.82 x 0.18

55.82 x 0.18 = 10.05

so the tip = $10.05

now we just add it to the original bill
55.82 + 10.05 = 65.87

so the total cost = $65.87

Which equation has a slope of 2 and a y-intercept of - 5?
X a. 2x + y = -5
b. 2x - y = 5
c.X + 2y = - 10
d. X - 2y = 10

Answers

Answer:

b. 2x - y = 5

you are able to change the equation to y = 2x -5. this is then in the form of y = mx + b.

m = slope and b = y-intercept

m = 2 and b = -5

Answer

d. x - 2y = 10

Step-by-step explanation:

The answer you chose does have the correct y intercept, but the incorrect slope, it was asking for a slope of 1/2, not a slope of -2.

REMEMBER: The y intercept is when x = 0, the x intercept is when y = 0.

To find the y intercept, substitute 0 for x, and solve for y. The slope is the coefficient of x when the coefficient of y is 1.

Just convert this standard form equation into slope intercept.

Standard Form: Ax + By = C.

Slope Intercept: y = mx + b. (m is the slope, b is the y intercept)

To convert just get y by itself completely on the left side of the equation. (y has to have a coefficient of positive 1)

x - 2y = 10

-x -x

-2y = -x + 10

÷2 ÷2 ÷2

-y = -1/2x + 5

×-1 ×-1 ×-1

y = 1/2x - 5 → y = mx + b

m = 1/2, and b = -5

Write a slope intercept equation for line with the given characteristics m=-3/5 passes through (4,-4)

Answers

Step-by-step explanation:

Hey there!

Given;

Slope (m) = -3/5

And passes through the point(4,-4).

Now; The equation of a line in slope intercept form is y= mx+b.

So, try to bring it in y= mx+b form.

Firstly let's use one-point formula.

[tex](y - y1) = m(x - x1)[/tex]

Now, keep all values.

[tex](y + 4) = \frac{ - 3}{5} (x - 4)[/tex]

Now, simplify to get answer.

[tex]5(y + 4) = - 3(x - 4)[/tex]

[tex]5y + 20 = - 3x + 12[/tex]

[tex]5y = - 3x + 12 - 20[/tex]

[tex]5y = - 3x - 8[/tex]

[tex]y = \frac{ - 3}{5} x - \frac{8}{5} [/tex]

Therefore the equation is y = -3/5x - 8/5.

Hope it helps...

Answer:

x = -7

Step-by-step explanation:

2(x - 5) = 4(x + 1)

Multiply the parenthesis by the outside numbers (simplify).

2x - 10 = 4x + 4

Combine like terms (add 20 to both sides, and subtract 2x).

0 = 2x + 14

Subtract 14 from both sides of the equation.

2x = - 14

Divide both sides of the equation by 2.

x = -7
