What is the formula for elimintation
inysia [295]

Answer:

The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

Chen has 17CDs. She gives 2 to her brother and buys 4 more. Her brother gives her 1 and she gives 3 to her best friend. How many
d1i1m1o1n [39]

Answer: she has 17 CDs now.

Step-by-step explanation:

The total number of CDs that Chen had initially is 17.

She gives 2 to her brother. This means that she would be having

17 - 2 = 15

She buys 4 more. It means that she would be having

15 + 4 = 19

Her brother gives her 1. So the number that she has is

19 + 1 = 20

she gives 3 to her best friend. Therefore, the number of CDs that Chen has now is

20 - 3 = 17

A farmer sells 7.8 kilograms of pears and apples at the farmer's market. 3/4 of this weight is pears, and the rest is apples. Ho
tangare [24]

Answer:

He sold 1.95 kilograms of apples.

Step-by-step explanation:

First we find out what 3/4 of 7.8 is.

3/4 of 7.8 = 5.85

Next we subtract 7.8 by 5.85

7.8 - 5.85 = 1.95

So, the answer is 1.95

Hope this helps! :)

What is the value of x?
nika2105 [10]

AC is the hypotenuse of triangle ABC.

Because the length is 6√2 and angle A is 45 degrees, we know the length of both sides is 6.

This means AB is 6, which it the hypotenuse of triangle BCD.

Using cos(angle) = adjacent leg / hypotenuse we can find x:

cos(60) = X / 6

x = 6 * cos(60)

x = 3
