BRAINLIEST FOR THE CORRECT AWNSER!! PLEASE PUT THE LETTER AWNSER AND EXPLAIN DO NOT LIE THANK YOU The owner of a bike shop sells

unicycles and bicycles and keeps inventory by counting seats and wheels. One day, she counts 15 seats and 22 wheels. The equation representing the total number of seats is u + b = 15 where u is the number of unicycles and b is the number of bicycles. Select the equation representing the number of wheels. A. u + 2b = 22 B. 2u + b = 15 C. u + 2b = 15 D. 2u + b = 22

Answer:

u+2b=22

Unicycles have one wheel and bicycles have two, so the coefficient of 2 should go before the variable representing each bike.

It should equal 22 because 15 represents the total number of seats and not wheels.

A plane takes off from an airport and flies at a speed of 400km/h on a course of 120° for 2 hours. the plane then changes its co
butalik [34]

Answer:

Distance from the airport = 894.43 km

Step-by-step explanation:

Displacement and Velocity

The velocity of an object assumed as constant in time can be computed as

\displaystyle \vec{v}=\frac{\vec{x}}{t}

Where \vec x is the displacement. Both the velocity and displacement are vectors. The displacement can be computed from the above relation as

\displaystyle \vec{x}=\vec{v}.t

The plane goes at 400 Km/h on a course of 120° for 2 hours. We can compute the components of the velocity as

\displaystyle \vec{v_1}=

\displaystyle \vec{v_1}=\ km/h

The displacement of the plane in 2 hours is

\displaystyle \vec{x_1}=\vec{v_1}.t_1=.(2)

\displaystyle \vec{x_1}=km

Now the plane keeps the same speed but now its course is 210° for 1 hour. The components of the velocity are

\displaystyle \vec{v_2}=

\displaystyle \vec{v_2}=km/h

The displacement in 1 hour is

\displaystyle \vec{x_2}=\vec{v_2}.t_2=.(1)

\displaystyle \vec{x_2}=km

The total displacement is the vector sum of both

\displaystyle \vec{x_t}=\vec{x_1}+\vec{x_2}=+

\displaystyle \vec{x_t}=km

\displaystyle \vec{x_t}=

The distance from the airport is the module of the displacement:

\displaystyle |\vec{x_t}|=\sqrt{(-746.41)^2+492.82^2}

\displaystyle |\vec{x_t}|=894.43\ km

Brad bought a used bike for $8 more than half of its original price. Brad paid $40 for the bike. What was the original price?
Viefleur [7K]

\huge\boxed{\$64}

Start by writing a formula, where x is Brad's purchase price and y is the original price.

40=8+\frac{y}{2}

Subtract 8 from both sides.

32=\frac{y}{2}

Multiply both sides by 2.

\boxed{64}=y
