Step-by-step explanation:

add all the numbers:)

Answer:

12249580

Step-by-step explanation:

This system can be solved for x by elimination.

[tex]6x - 3y = 15\\ x + 3y = -8\\\\7x = 7\\\\x = 1[/tex]

Now, with what we found for x, we plug it back into one of the equations to solve for y. I chose the second one.

[tex]1 + 3y = -8\\\\3y = -9\\\\y = -3[/tex]

Now, we have our solution.

[tex](1, -3)[/tex]

Answer:

(1,-3)

Step-by-step explanation:

6x-3y=15

substitute x with 1 and y with -3

6(1)-3(-3)=15

6+9=15 so that's true

x+3y=-8

again substitute x with 1 and y with -3

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

1-9=-8

-8=-8 and that's true

hope i helped

make me the branliest  the answer is C

Step-by-step explanation:

Pool X has 1200 gallons of water in it. It is being drained at a rate of 15 gallons per minute. If lowercase x is the number of minutes, then it has 1200-15x gallons left in the pool.

Consider after 1 minute we have x = 1, so,

1200-15x = 1200-15*1 = 1200-15 = 11185

Then after 2 minutes we have x = 2, which means,

1200-15x = 1200-15*2 = 1200-30 = 11170

is the amount left over in gallons.

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

In contrast, Pool Y is empty and we add 25 gallons per minute. So we start with 0 and add on 25x getting 0+25x = 25x as the expression representing the amount of gallons of water in Pool Y

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

So we found these two expressions

1200-15x

25x

to represent the amount of water (in gallons) for Pool X and Pool Y respectively.

We want to know when Pool Y will have more water. So we get to this final answer

1200 - 15x < 25x

It is in the form A < B, where A  is the amount of water in Pool X and B is the amount of water in Pool Y.

Answer:

The total number of votes was 7968.

Step-by-step explanation:

From the information given, you know that the ratio of yes votes to no votes was 7 to 5 and you can use a rule of three to find the number of no votes if there were 4648 yes votes:

    7 yes    →   5 no

4648 yes  →      x

x=(4648*5)/7=3320

Now, you have to add up the amount of yes votes and no votes:

4648+3320=7968

According to this, the answer is that the total number of votes was 7968.

Answer:

x = 17

Step-by-step explanation:

For the lines to be parallel, then

(8x - 31) and (6x + 3) are alternate angles and congruent, then

8x - 31 = 6x + 3 ( subtract 6x from both sides )

2x - 31 = 3 ( add 31 to both sides )

2x = 34 ( divide both sides by 2 )

x = 17

Answer:

seed Mix A is more expensive than Seed Mix B.

Step-by-step explanation:

The graph of Mix A is above the graph of Mix B.

Looking at the labels of the graphs, we see that the x-axis represents the number of bags bought and the y-axis represents the cost.

For every point along the x-axis, Mix A's cost is above Mix B's cost.  This means that Mix A is more expensive.Step-by-step explanation:

Answer:

A is more money than B

Answer:

$19

Step-by-step explanation:

First you need to make a equation out of given information and this will be easiest to solve as an equation.

3.5      $66.50

1               x

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

3.5:1=66.50:x

3.5x=66.50/:3.5

x=19

On the right side you put one information(in this case number of yards) and on the left other information(cost) and you make proportion from up to down and solve for x.

 =  5

Step-by-step explanation:

1. Add 8 to both sides of the equation

2 . Simplify

3 . Subtract  4  from both sides of the equation

4 . Simplify  ( combine like terms )

5 . Divide both sides of the equation by the same term

6 . Simplify

Answer:

Can I please have Brainlyest

Step-by-step explanation:

Hope you have a great day LOL :)

Answer:

$2.50

Step-by-step explanation:

Given the daily pay formula :

P(b)=5/2b+45

P(b) = employee’s total daily pay

b = number of bushels of peaches picked

Hence from the fórmula ; rate which employees are paid per bushel. Of peach picked is the gradient of the equation :

According to the intercept slope formula:

y = mx + c ; where m = slope or gradient

From the equation :

P(b)=5/2b+45

The slope or gradient is 5/2 ; hence, employees are paid $5/2 per bushel of peaches picked.

$5/2 = $2.50

Answer:

B- ¿120 kg?

Step-by-step explanation:

Dado que la información proporcionada menciona que en Mercurio las cosas pesan 4 veces menos que en la Tierra, para encontrar el peso en la Tierra cuando tienes el precio del objeto en Mercurio, tienes que multiplicar este peso por 4:

30kg*4=120 kg

De acuerdo a esto, la respuesta es que el objeto pesará 120 kg en la Tierra.

Answer:

120 kg pesa el objeto en la tierra

Explicación paso a paso:

Tierra. Mercurio

1kg ----- 1/4 kg

¿? ---------- 30gk

Regla de tres..

1X30 ÷ (1/4)

= 120 kg pesa el objeto en la tierra.

Step-by-step explanation:

-2/3x+ 3/7 = 1/2

-2/3x = 1/2 -3/7

-2/3x = 7-6 /14

-2/3x = 1/14

3x = 1/14×(-2)

3x = 1/ -28

x = 1/ -28×3

x = 1/-84

Answer:

B. 295,35 sq ft

Step-by-step explanation:

We are told that the outside dimensions of a living room are 13' 0" x 22' 0".

Since the wall has a thickness of 5 1/8", then the internal dimensions are;

Length = 22' 0" - 5⅛" - 5⅛" = 21' 1¾"

Width = 13' 0" - 5⅛" - 5⅛" = 12' 1¾"

The floor area will be length × width.

So let's convert length and width to feet

Length = 21' 1¾" = 21.1458 ft

Width = 12' 1¾" = 12.1458 ft

Area of floor required = 21.1458 × 12.1458 = 256.83

Allowing 15% for waste gives us;

Area provided = 256.83 × 1.15 = 295.35 Sq.ft
