Answer:

Step-by-step explanation:

-x + 5y - 7 = 0

-x + 5y = 7 --------------------(I)

4y - 10 = 5x

-10 = 5x - 4y

5x - 4y = -10 -----------------------(II)

             -x + 5y = 7 --------------------(I)

             5x - 4y = -10 -----------------------(II)

Multiply equation (I) by 5.

(I)*5     -5x + 25y = 35

(II)        <u>5x -   4y    = -10</u>    {Now add and x will be eliminates}

                  21y   = 25

y = 25/21

Substitute y value in Equation (I)

-x + 5*25/21 = 7

-x + 125/21 = 7

-x = 7 - (125/21)

-x = (147/21) - (125/21)

-x = (147-125)/21

-x = 22/21

x = -22/21

Answer:

x = -22/21

y=  25/21

Step-by-step explanation:

-x+5y-7x=0

4y-10=5x

(-x-5y-7)+7=0

(-4y-10)+(10-5x)= 5x+(10-5x)

x =-22/21

y = 25/21

Naddik [55]
We know that out of the 1996 people, 294 had high blood pressure. We can use that to create a fraction.

294/1996 = 147/998 = 0.14729...

The probability of the next person having blood pressure is about 15%.

Explain why the steps for solving equations are usually given as removing grouping symbols first, even though it is not necessar
finlep [7]
This is because simplifying the equation before solving it will lead you to the answer at a much faster rate. For example, in the given equation, the long way would be to distribute 2 to (x+3). Then, you transpose them and combine like terms. Until you get to x + 3 = 8. But if you simplify it first, you will see that it is straightforward. It will lead you to the answer right away which is x + 3 = 8. It saves you from the hassle of doing more algebra :)

Mars2501 [29]

Answer: 1/16 of a pound

Step-by-step explanation:

Here is the complete question:

Jordan bought 9/16 of a pound of sunflower seeds and divided them evenly into 9 snack bags for his lunch. What is the weight of sunflower seeds in each snack bag?

1/16 of a pound

1/9of a pound

16/81 of a pound

81/16 pounds

From the question, we are told that Jordan bought 9/16 of a pound of sunflower seeds and then divided them equally into 9 snack bags for his lunch. To get the weight of sunflower seeds in each snack bag, we will divide 9/16 by 9 snack bags. This can be written mathematically as:

= 9/16 ÷ 9

= 9/16 × 1/9

= 1/16

The weight of sunflower seeds in each snack bag will be 1/16 of a pound.
