Answer:

see below

Step-by-step explanation:

1. (x² - 4x - 10) + (x² - 9x + 3)

=  x² - 4x - 10 + x² - 9x + 3

=  x² + x² - 4x - 9x + 3 - 10

<h3>= 2x² - 13x - 7 </h3>

4. (3x² - x + 1) + (15 - 9x - 2x²)

=  3x² - x + 1 + 15 - 9x - 2x²

= 3x² - 2x² - x - 9x + 1 + 15

<h3>= x² - 10x + 16 </h3>

7.  (6 - 2x + 7x²) - (10x - 3 + 3x²)

=   6 - 2x + 7x² - 10x + 3 - 3x²

=  7x² - 3x² - 2x - 10x + 6 + 3

<h3>=  4x² - 12x + 9</h3>

Leto [7]

Answer:

2.45c + 1.65c = 4.12 + 0.75

Step-by-step explanation:

To write an equation to find the value for c, we need to declare what c is first.

c = price of fruit

2.45c + 1.65c = 4.12 + 0.75

Now we multiplied c to 2.45 and 1.65 and added them together, because whatever the value of c is will give us the equivalence of the sum of 4.12 + 0.75.

Now to check if the equation is right, let's solve for c.

2.45c + 1.65c = 4.12 + 0.75

4.1c = 4.87

Now to get the value of c, we divide both sides of the equation by 4.1.

\dfrac{4.1c}{4.1}=\dfrac{4.87}{4.1}

c = 1.19

Now let's substitute the value of c in the equation to see if we got it right.

2.45(1.19) + 1.65(1.19) = 4.12 + 0.75

2.92 + 1.96 = 4.87

4.87 = 4.87

Therefore concluding that the value of c is 1.19.

A system of two linear equations with two variables is shown below.
Orlov [11]
{ 3-y=2x
{ x+1/2y=3/2

{ -y=2x-3
{ 1/2y=3/2-x

{ y=-2x+3
{ y=3-2x

-2x+3=3-2x

(x,y) = (x,-2x+3)
