Answer:

hello the system related to your question is missing below is the system

–3x + y – 2z = 10 --------(1)

5x – 2y – 2z = 12 -------- (2)

x – y + z = 23  ----------- (3)

answer :

To reduce the system above to  a 2 * 2 , I would eliminate either Y or Z from the system because a 2 * 2 system requires  X and either Y or Z

Step-by-step explanation:

Given system :

–3x + y – 2z = 10 --------(1)

5x – 2y – 2z = 12 -------- (2)

x – y + z = 23  ----------- (3)

To reduce the system above to  a 2 * 2 , I would eliminate either Y or Z from the system because a 2 * 2 system requires  X and either Y or Z

Eliminating X is not the best way

solving equation 1 and 2

substrate equation (1 ) from equation (2) to eliminate Z

= 8x - 3y = 2

multiply equation (3) by 2 then substrate equation (2) from (3) to eliminate Y

2x - 2y + 2z = 46

-( 5x - 2y - 2z )=  12

= -3x + 4z = 34

Answer:

the fraction of the total distance traveled on the sunday is [tex]\frac{4}{7}[/tex]

Step-by-step explanation:

The computation of the fraction of the total distance traveled on the sunday is given below:

[tex]= 1 - \frac{2}{7} \times \frac{4}{5}\\\\= \frac{5}{7} \times \frac{4}{5}\\\\= \frac{4}{7}[/tex]

Hence, the fraction of the total distance traveled on the sunday is [tex]\frac{4}{7}[/tex]

We simply multiplied the two fractions

Answer: Marcy used [tex]\dfrac{35}8[/tex] cartons of blueberries for the first batch of pies.

Step-by-step explanation:

Given: Quantities of blueberries = [tex]8\dfrac34[/tex] cartons

[tex]=\dfrac{8\times4+3}{4}=\dfrac{35}{4}[/tex] cartons

Blueberries used for first batch = [tex]\dfrac12[/tex] of (Total)

[tex]=\dfrac12\times\dfrac{35}{4}\\\\=\dfrac{35}{8}[/tex]cartons

Hence, Marcy used [tex]\dfrac{35}8[/tex] cartons of blueberries for the first batch of pies.

Answer:

y = -2x - 1

Step-by-step explanation:

If you already know the slope. Just find out the y-intercept. Plug the coordinates into the equation.

y = mx + b

y = -2x + b

1 = -2(1) + b

1 = -2 + b

-1 = b

Answer:

69632

Step-by-step explanation:

Order of operations

First Parenthesis then exponents; however in the parenthesis we have an exponent so first we do the exponent and then the addition.

4^4 x (6^3 + 56) = ?

4^4 x (216 + 56)

4^4 x (272) = ?

then we do the exponents and after that multiply

256 x 272

Answer:

A. y + 3 = -5(x - 2)

Step-by-step explanation:

The slope is:

2 - (-3) / 1 - 2 = 5 / -1 = -5.

Then, put it in point slope form (which was [tex](y - y1) = m(x-x1)[/tex] where m is the slope, and (x1, y1) is the coordinate point it gives you. You can use m = -5, x1 = 2 and y1 = -3.)

y + 3 = -5(x - 2)

Answer:

294

Step-by-step explanation:

We are given the area of 1 face of a cube. The area is 49. Now if their are 6 faces in a cube, and all faces of a cube are the same, then we multiply 49*6 = 294.

The number of footballs that are for sales when its known that there are total 318 footballs and basketballs and there are 76 more footballs for sale than basketballs, is given by: Option C: 197

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

Given that:

Assume that:

Then we get two equations, as:

[tex]x+y = 318\\x = 76 + y[/tex]

Substituting the variable x in first equation by the expression obtained in second equation for x, we get:

[tex]x + y = 318\\(76 + y) + y = 318\\76 + 2y = 318\\\text{Subtracting 76 from both the sides}\\\\2y = 318 - 76 = 242\\\\\\2y = 242\\\\\text{Dividing both the sides by 2}\\\\y = \dfrac{242}{2} = 121[/tex]

Thus, we got: Number of basketballs  = y = 121

Using this result and the first equation, we get:

[tex]x + 121 = 318\\x = 318 - 121 = 197[/tex] = number of footballs.

Thus, the number of footballs that are for sales when its known that there are total 318 footballs and basketballs and there are 76 more footballs for sale than basketballs, is given by: Option C: 197

Answer:

B) 3√2

Step-by-step explanation:

FH = √GH²+FG² = √18 = 3√2

first step is to subtract 21 from both sides

2m+21-21=3-21

2m=-18

2m/2 and -18/2

m=-9

So the final answer is m=-9 (negative nine equals m)
