Answer:

For answer a,

the equation is -1 - 5

this equals -6

From -1 to -6 is 5

A.) The difference is 5

For answer b,

the equation is  -7 - (-3)

There are two minus signs by the -3 so that means to turn those two signs into a plus sign

- 7 + 3

Start at -7 and move to the right 3

You will end up at -4

B.) The difference is 3

In the equation 6x – 2 = –4x + 2, Spencer claims that the first step is to add 4x to both sides. Jeremiah claims that the first
Sergeeva-Olga [200]
If you would like to know who is correct, you can find this using the following step:

<span>6x - 2 = -4x + 2

Spencer: 
</span>6x - 2 = -4x + 2       /+4x
6x - 2 + 4x = -4x + 2 + 4x
10x - 2 = 2

Jeremiah:
6x - 2 = -4x + 2      /-6x
6x - 2 - 6x = -4x + 2 - 6x
-2 = -10x + 2

They both are correct. But in Jeremiah's version of solving the equation, we would have to multiply equation by -1 (or add 10x to both sides), which we don't have to do in the Spencer's version.

Solving Two-Step Inequalities
Nuetrik [128]

Answer:

x > \frac{9}{5}

Step-by-step explanation:

Given

\frac{2}{3} x - \frac{1}{5} > 1

Multiply through by 15 to clear the fractions

10x - 3 > 15 ( add 3 to both sides )

10x > 18 ( divide both sides by 10 )

x > \frac{18}{10} , that is

x > \frac{9}{5}

A billiard ball is struck by a cue. It travels 100 cm before ricocheting off a rail and traveling another 100 cm into a corner p
Airida [17]

Answer:

76.53 cm

Step-by-step explanation:

From the question, the triangle formed has 2 sides and an included angle ;

Angle, θ = C = 45°

We use cosine rule :

Taking the side to find as c

a = 100 ; b = 100

From cosine rule :

c = sqrt(a² + b² - 2abCosC)

c = sqrt(100² + 100² - 2(100*100)Cos45

c = sqrt(10000 + 10000 - 20000 * 0.7071067)

c = sqrt(20000 - 14142.135)

c = sqrt(5857.865)

c = 76.536690

c = 76.53 cm
