What is the results of adding these two equations?<br> 6x+2y=-2<br> 3x-2y=-5

Bess [88]

Answer:

x=-7/9, y=4/3. (-7/9, 4/3).

Step-by-step explanation:

6x+2y=-2

3x-2y=-5

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

9x=-7

x=-7/9

6(-7/9)+2y=-2

-42/9+2y=-2

2y=-2-(-42/9)

2y=-2+42/9

2y=-18/9+42/9

2y=24/9

y=(24/9)/2

y=(24/9)(1/2)

y=24/18

y=4/3

Herbert has sold 90, 45, 103 and 68 appliances in the last four months, respectively. How many appliances will he need to sell t

Elena-2011 [213]

Answer:

The sale this month = 79

Step-by-step explanation:

Let the amount he needs to sell this month = x

$Average = \frac{sum\ of\ individual\ data\ }{number\ of\ entries}$

$Average= \frac{90\ +\ 45\ +\ 103\ +\ 68\ +\ x}{5}$

Note that number of entries = number of months = 5

To maintain an average sales of 77, the amount of sale in month 5 is determined as follows:

$77 = \frac{306\ +\ x}{5} \\cross-multiplying\\77\ \times\ 5\ = 306\ +\ x\\385 = 306\ +\ x\\x =385\ -\ 306\\x = 79$

Rama09 [41]

Answer: The sash will have 20 diamonds when it is completed.

Step-by-step explanation:

Given: The length of American sash= 8 feet

Since, Joseph wants to add a diamond shape every 0.4 ft along the sash.

Therefore, the number of diamonds he will need to complete the sash= $\frac{8}{0.4}$

⇒ The number of diamonds he will need to complete the sash= $\frac{80}{4}=20$

Hence, the number of diamonds he will need to complete the sash= 20

You are selling concessions at a local swim meet. Hot dogs are being sold for $1.00 and soda is being sold for $0.50. At the end

melomori [17]

Answer:

use this equation: 150=1x+0.5y

Step-by-step explanation:

a) standard form equation above

b) 150=1x+0.5y

subtract 1x from both sides

then divide all by 0.5 to get slope intercept form

c) plug it in: 150=1(40)+0.5y and solve to get 220

d) take the y intercept from answer b. and the y intercept shows how many you have to sell of each to reach you $150(I think, this part might be wrong...idk)
