Help please lol..forgot how to do this

Answer:

80

Step-by-step explanation:

multiply both sides by 5

3x +50 = 4x -30

combine like terms

-x = -80

x = 80

Answer:

B

Step-by-step explanation:

One way to tell is to put both equations into slope-intercept form.  That form is usually written [tex]y=mx+b[/tex] where  m  is the slope and  b  is the y-intercept.

Solve the first equation for y.

[tex]6x+2y=5 \\ 2y=-6x+5 \\ y=-3x+5/2[/tex]

The slope of this line is -3, and its y-intercept is 5/2.

Solve the second equation for y.

[tex]y+3x=2\\y=-3x+2[/tex]

The slope of this line is -3 and its y-intercept is 2.

The lines are parallel because they have the same slope and different y-intercepts.  There is no solution to the system.

Answer:

$10,857.8

Step-by-step explanation:

Brad wants to have $17000 available to buy a car in 5 years. How much should he deposit now at 9% compounded monthly to reach that goal?

A = p(1 + r/n)^nt

P = A / (1 + r/n)^nt

P = 17000 / (1 + 0.09/12)^(12*5)

= 17,0000 / (1 + 0.0075)^60

= 17,000 / (1.0075)^60

= 17,000 / 1.5657

= 10,857.8

P = $10,857.8

C. Print Nothing

Step-by-step explanation:

For those who don't wanna read

Answer:

The program is going to print nothing because the script does not tell it to say anything other than when the grade (x) is greater than 90.

Therefore,the correct option is 3, print nothing

Step-by-step explanation:

Answer:

d) 2 tons plus 1,200 pounds.

Step-by-step explanation:

1 ton = 2000

2000 + 2000 = 4000

5200 - 4000

= 1200

hence, the answer is 2 tons plus 1,200 pounds.

hope this helps and is right :)

Answer:12220

Step-by-step explanation:

Answer:

1) y = 3/5x + 8

2) Slope: 10

   y-intercept: -1/3

3) y = -1/2x - 1

Step-by-step explanation:

1) The equation you need to refer to for this problem is y = mx+b

m = slope (3/5 for this problem)

b = y-intercept(which is 8)

plug those numbers in and you get y = 3/5x + 8

2) look back at this equation: y = mx+b

10 is the slope and -1/3 is the y-intercept

3) This one is a bit more difficult as you need two other formulas to solve:

the slope formula, y1 - y2/x1 - x2, and the point-slope formula,

y - y1 = m(x - x1)

For this problem, you have the coordinates (4, -3) and (6, -4) which you would plug into the slope formula, like this:

-3 -(-4)/4 - 6 = -1/2

the numbers 1 and 2 in this formula refer to the first (x,y) value and the second. You subtract the two y values and the two x values, simplify, and you get your answer.

-1/2 is going to be the m, or slope, that you will use in the second formula, the point slope formula, y - y1 = m(x - x1)

To solve this you choose one of the original coordinates that you were given to plug into the y1 and x1, and plug -1/2, your slope, in for m:

(keep in mind, for this, I used (4,-3) but you can use either one)

y -(-3) = -1/2(x - 4)

To solve this you, first, distribute -1/2 to x and -4 inside the parentheses:

y -(-3) = -1/2x + 2

Then, on the other side, add the to negatives to get a positive 3:

y + 3 = -1/2x + 2

and subtract 3 from both sides:

y = -1/2x - 1

I hope this isn't too confusing

good luck!

Answer:

Step-by-step explanation:

25 - 32 = -7  and 18 - 25 = -7

It means an arithmetic sequence with common difference d = -7

[tex]a_n = a_1+d(n-1)\\\\a_1=32\\d=-7\\\\a_n=32+(-7)(n-1)\\\\a_n = 32-7n+7\\\\\underline{a_n=-7n+39}[/tex]

Answer:

Volume of the cylinder is 588π cm³ Or 1846.32 cm³

Step-by-step explanation:

Area of a cylinder is given by the formula,

Volume = πr²h

Here, r = Radius of the circular base

h = Height of the cylinder

From the picture attached,

Radius of the given cylinder = 7 cm

Height of the cylinder = 12 cm

By substituting these values in the formula,

Volume of the cylinder = π(7)²(12)

                                      = 588π cm³

                                      ≈ 1846.32 cm³

Therefore, volume of the cylinder is 588π cm³ Or 1846.32 cm³.

Answer:

C) 12.5

 The length of BC = 12.5cm

Step-by-step explanation:

Step(i):-

Given that  ΔABC

Given that  AB =  15cm and ∠A =  40°

we will use trigonometric function

                     [tex]tan x = \frac{oppositeside}{adjacentside}[/tex]

                   [tex]tan 40^{0} = \frac{BC}{AB} = \frac{BC}{15}[/tex]

Step(ii):-

we know that tan40° = 0.83909

                 [tex]tan 40^{0} = \frac{BC}{15}[/tex]

                BC =  15 × tan 40°

                BC = 12.58649

                BC = 12.5cm

Final answer:-

 The length of BC = 12.5cm

Step-by-step explanation:

what is the question talking about

Answer:

C. 96 cm²

Step-by-step explanation:

Objętość sześcianu = 64 cm³

Krok 1

Znajdujemy długość boku sześcianu

Objętość = (długość boku) ³

64 = a³

a = pierwiastek sześcienny (64)

a = 4 cm

Krok 2

Znajdujemy obszar sześcianu

Wzór na całkowitą powierzchnię sześcianu = 6a²

a = 4 cm

Całkowita powierzchnia = 6 × 4²

= 6 × 16

= 96 cm²

Opcja C jest właściwą opcją
