somebody help me out

Answer:

Step-by-step explanation:

Set this up as a proportion of M:P

[tex]\frac{M}{P}:\frac{2}{5}=\frac{200}{x}[/tex] and cross multiply to solve for x:

2x = 1000 so

x = 500. Peter got $500

Answer:

The solution to the system of equations is y = -5 and x = -2.

Step-by-step explanation:

The question tells us to use substitution to solve the system.  This means that the given value for x (in terms of y) should be substituted into the other equation.  This is modeled below:

-4y - 5x = 30

-4y - 5(y+3) = 30

Next, we should use the distributive property to simplify the left side of the equation.

-4y -5y - 15 = 30

The next step is to combine like terms on the left side of the equation.

-9y - 15 = 30

Then, we can add 15 to both sides of the equation.

-9y = 45

Finally, we can divide both sides of the equation by -9.

y = -5

To find the value for x, we substitute in the value we just found for y into either of our original equations.

x = y + 3

x = -5 + 3

x = -2

Therefore, the correct answer is y = -5 and x = -2.

Answer:

The paint will not fill the tray by 10.53 in3.

Step-by-step explanation:

Length = 14 inches

Width = 10 inches

Depth = 4 cm = 1.57 inches

Volume = length x width x depth

Volume = 14 x 10 x 1.57

= 220.47 inches cube

Volume of Gallon = 231 inches cube

Answer:

2x² + 5x - 3

Step-by-step explanation:

(x + 3)(2x - 1)

Use FOIL

First terms

x * 2x = 2x²

Outer terms

x * -1 = -x

Inner terms

3 * 2x = 6x

Last terms

3 * -1 = -3

---------------------

FOIL

2x² - x + 6x - 3

Combine like terms

2x² + 5x - 3

Answer:

ok is this a troll

Step-by-step explanation:

the cake doesnot correspond to the cookie

Answer:

2.3%

Step-by-step explanation:

18000 = 15000( 1 + i)^8

Divide both sides by 15000

1.2 = (1 + i)^8

Take both sides to the 1/8 power

1.2^(1/8) = 1 + i

1.023051875220463 = 1 + i

Subtract 1 from both sides

i = 0.023051875220463

~ 2.3%

Q1: I forgot measure of center but I think mean  Q2: D

Step-by-step explanation:

Answer:

x = a(y+17)^2 + 2 where a < 0

Step-by-step explanation:

Since the parabola is horizontal, the formula of the parabola is x = a(y-h)^2 + k where (h,k) is the vertex.

Since it opens to the left, a must be negative. The vertex is (-17, 2), so h = -17 and k = 2.

Substituting these in, we find that the equation is

x = a(y+17)^2 + 2 where a is a real number that is less than 0 (i.e. negative)

Answer:

x = 16

Step-by-step explanation:

2x - 3 + 23 + 128= 180

Combine like terms

2x+148 = 180

Subtract 148 from each side

2x+148-148= 180-148

2x =32

Divide by 2

2x/2 =32/2

x = 16

Answer:

    X=16

Step-by-step explanation:

Combine like terms so 3+23+128= 148

Rewrite: 2x + 148= 180

Next subtract 148 from both sides

2x + 148 (-148) = 180 (-148)

Cancel out 148 and you get 2x=32

Divide by 2

2x = 32

2       2

x= 16

Hope this helped have a wonderful day!! <3 :))

Answer:

Step-by-step explanation:

Lets understand what the question says:-

Mean or average in a list=16

Total sum of observations= x

Equation:-

x/10=16

x=160

If 2 numbers are increased by 5 that means

New sum of observations=160+10=170

Therefore,

New average or new mean=170/10=17

Therefore the average gets increased by 1

Hello!

Step-by-step explanation:

Theoretical probability is what's expected to happen

Experimental probability is what's happen based on the experiment

Daisy gets 20 cats delivered to her shelter in the last month She expects to get 20 this month based on the theoretical probability but she actually gets 15 cats this month so her theoretical probability was 5 more then her experimental probability Hope that helps!

Answer:

14 cm

Step-by-step explanation:

The maximum area of a rectangle (actually square) with a perimeter of 14 can have is 12.25 cm².  So the smallest perimeter a rectangle of 12 cm² i just a little below 14 cm, namely 4sqrt(12) = 13.86 cm.
