Kami is cooking dinner for a family reunion that 21 people are attending. If her recipe calls for 1.6 ounces of ground beef per person, how much beef does Kami need altogether?

Answers

Answer:

Kami will need 33.6 ounces of ground beef for the recipe

Step-by-step explanation:

From the problem, we know that one person will use up 1.6 ounces of ground beef. We also know that there are 21 people that will be attending the party. Each of those 21 people will definitely use up 1.6 ounces of ground beef.

Hence, for the recipe to be perfect, Kami will have to use 21 X 1.6 ounces  = 33.6 ounces of ground to make the recipe for the entire dinner.

Given the graphs of y = f(x) and y = g(x),
g(x) = f(x)
expresses g(x) in terms of f(x).

Answers

Step-by-step explanation:

g(x) = f(x) + 4.

This is because g(x) is a translation of f(x) that has been moved up by 4 units. (-2 to 2 when x = 0)

Given the graphs of y = f(x) and y = g(x),

g(x) = f(x)  + 3

expresses g(x) in terms of f(x).

Which strategie would eliminate a variable in the system of equations? −x+6y=8 7x−y=−2 ​

Answers

Answer:

  substitution (or addition)

Step-by-step explanation:

A simple strategy for this system is to use substitution. The first equation is easily solved for x, so you could substitute that into the second equation:

  x = 6y -8

  7(6y -8) -y = -2 . . . . . x variable eliminated

__

The second equation is easily solved for y, so you could substitute that into the first equation.

  y = 7x +2

  -x +6(7x +2) = 8 . . . . . y-variable eliminated

__

The "addition" method is always a good way to eliminate a variable.

When the coefficient of a variable in one equation is a divisor of the coefficient of that variable in the other equation, a simple multiplication and addition will do.

To make the coefficient of x in the first equation the opposite of the coefficient of x in the second, multiply the first equation by 7. Adding that result to the second equation will eliminate x:

   7(-x +6y) +(7x -y) = 7(8) +(-2)

  42y -y = 56 -2 . . . . . . x-variable eliminated

Likewise, the second equation can be multiplied by 6 and added to the first to eliminate the y-variable:

  (-x +6y) +6(7x -y) = (8) +6(-2)

  -x +42x = -4 . . . . . . . . y-variable eliminated

__

It is often the case that using either substitution or "addition" requires about the same amount of work.

Here, the solutions are (x, y) = (-4/41, 54/41).

Answer:

636 in.²

Step-by-step explanation:

First divide the shape into three pieces, you will get a triangle and two rectangles, the base of the triangle is 30 in. The height is 8 in. Multiply 30×8 to get 240 and then divide by two to get 120. Next the rectangle on top has sides that are 24 in. and 8 in. You will get 192. Lastly the rectangle on the bottom has sides of 54 in. and 6 in. For this you will get 324. Finally you add up 120+192+324 to get 636 in.²

If Sue ate half of the 8/9 pounds, that would equal to 4/9 pounds of pretzel.

3(x-1)-2(2x+1)=8(x-1)

Answers

Answer:

x = 1/3

Step-by-step explanation:

3(x-1)-2(2x+1)=8(x-1)

Distribute

3x -3  -4x-2  = 8x -8

Combine like terms

-x -5 = 8x -8

Add x to each side

-x-5+x = 8x-8+x

-5 = 9x-8

Add 8 to each side

-5+8 = 9x-8+8

3 = 9x

Divide by 9

3/9 = 9x/8

1/3 =x

3(x-1)-2(2x+1)=8(x-1)

Use distributive property:

3x-3 -4x-2 = 8x-8

Combine like terms:

-x -5 = 8x -8

Add 8 to both sides:

-x +3 = 8x

Add x to both sides:

3 = 9x

Divide both sides by 9:

x = 3/9

x = 1/3

4x^-4/9y^6

Step-by-step explanation:

If the exponent is outside the bracket, it means that all the terms inside will be raised to that exponent. This means that:

(2x^-2 / 3y^3)^2 = 2^2*(x^-2)^2 / 3^2*(y^3)^2

When exponents are raised to an exponent, the exponents are multiplied together, so (x^-2)^2 will = x^(-2*2) = x^-4

Going through:

2^2*(x^-2)^2 / 3^2*(y^3)^2

=4*x^-4 / 9*y^6
