[tex] x = 7 \frac{7}{8} [/tex]
Step-by-step explanation:
[tex] \frac{2}{9} x + \frac{2}{3} x = 7 \\ \\ \frac{2}{9} x + \frac{2 \times 3}{3 \times 3} x = 7 \\ \\ \frac{2}{9} x + \frac{6}{9} x = 7 \\ \\ \frac{2 + 6}{9} x = 7 \\ \\ \frac{8}{9} x = 7 \\ \\ x = 7 \times \frac{9}{8} \\ \\ x = \frac{63}{8} \\ \\ x = 7 \frac{7}{8} [/tex]

101 = -4 + 5(x + 2)
101 = -4 + 5x + 25
101 = 21 + 5x
101 - 21 = 5x
80 = 5x
80/5x
x = 16

Write an equation of the line that passes me that passes through (2,-5) and is parrallel to the line 2y=3x+10
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

If 2c - 5 = 3d + 4, what does c equal, in terms of d?
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.
A 10.0kg cart traveling East at 5.00 m/s collides with a 7.50kg cart traveling 3.00m/s at an angle of 55.0o. The two carts collide and stick together. What is the velocity of the cars after they stick together?
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.
