Answer:

D. [tex]\frac{3d+9}{2}[/tex]

Step-by-step explanation:

2c - 5 = 3d + 4

Isolate 2c.

2c = 3d + 4 + 5

Simplify.

2c = 3d + 9

(2c ÷ 2 = c) Find c.

c = [tex]\frac{3d+9}{2}[/tex]

Answer:

[tex]d. \: \frac{3d + 9}{2} [/tex]

Step-by-step explanation:

Follow the steps below.

[tex]2c - 5 = 3d + 4 \\ 2c = 3d + 9 \\ c = \frac{3}{2} d + \frac{9}{2} \: or \: c = \frac{3d + 9}{2} [/tex]

So D is correct.

Answer:

The magnitude of the velocity of the cars after they stick is approximately 3.7 m/s

Step-by-step explanation:

The given parameters are;

The mass of the cart traveling East, m₁ = 10.0 kg

The speed of the cart traveling East v₁=  5.00 m/s

The mass of the cart traveling at an angle of 55° m₂= 7.50 kg

The speed of the cart traveling at an angle of 55°, v₂ = 3.00 m/s

The component of the velocities of the cart raveling at an angle are given as follows;

v = 3.00 × cos(55°)·i + 3.00 × sin(55°)·j

The total momentum before collision = m₁ × v₁ + m₂ × v₂  by substitution is therefore;

m₁ × v₁ + m₂ × v₂ = 10 × 5.00·i + 7.5 × (3.00 × cos(55°)·i + 3.00 × sin(55°)·j)

The total momentum after collision = (m₁ + m₂) × v₃

By the principle of the conservation of linear momentum, whereby the momentum is conserved, we have;

m₁ × v₁ + m₂ × v₂ = (m₁ + m₂) × v₃

10 × 5.00·i + 7.5 × (3.00 × cos(55°)·i + 3.00 × sin(55°)·j) = (10 + 7.5) × v₃

50.00·i + 12.91·i + 18.43·j = 17.5·v₃

62.91·i + 18.43·j = 17.5·v₃

∴ v₃ = (62.91·i + 18.43·j)/17.5 ≈ 3.59·i + 1.05·j

Therefore, the magnitude of the velocity of the cars after they stick = √(3.59² + 1.053²) ≈ 3.7

The magnitude of the velocity of the cars after they stick ≈ 3.7 m/s.

Answer: x>5

If I Helped, Please Mark Me As Brainliest, Have A Great Day :D

Answer: x is greater than 5

Step-by-step explanation:

9(2(5)-9)-5 greater than 4

9(10-9)-5 greater than 4

9-5 greater than 4

4 greater than 4

So x MUST be greater than 5

Answer:

Answer:

i think b if im wrong

sorry]

iStep-by-step explanation:

Answer:

The answer is

A. 10 + 6 = x

And

C. x + ___ = 16

Because variables are letters, for example 7x, X is the variable and 7 is the number. The variable can be any letters in the alphabet A-Z.

Step-by-step explanation:

parallel means same slope/gradient

2y = 3x + 10

y = 1.5x + 5

let equation be y = 1.5x + b

sub (2, -5)

-5 = 1.5(2) + b

b = -8

therefore y = 1.5x - 8
