Answer:

y=10

Step-by-step explanation:

1. Make sure that the variable is left alone on the other side of the equal sign

2. remove all the no. on the variable side

3. subtract 23 from both sides hence left with 4y

4. divide the 40 u by 4 hence giving u 10

Pls answer with explanation!

patriot [66]

Answer:

3,750 cars.

Step-by-step explanation:

We are given that the equation:

$y=9000-2.4x$

Models the relationsip between y, the number of unfilled seats in the stadium, and x, the number of cars in the parking lot.

We want to determine the number of cars in the parking lot when there are no unfilled seats in the stadium.

When there are no unfilled seats in the stadium, y = 0. Thus:

$0=9000-2.4x$

Solve for x. Subtract 9000 from both sides:

$-2.4x=-9000$

Divide both sides by -2.4:

$x=3750$

So, there will be 3,750 cars in the parking lot when there are no unfilled seats in the stadium.

The second angle of a triangle is double the first angle. The third angle is 40 less than the first angle. Find the three angles

ArbitrLikvidat [17]

Answer:

Angle 1: 55

Angle 2: 110

Angle 3: 15

Step-by-step explanation:

Angle 1: x

Angle 2: 2x

Angle 3: x-40

The total degrees for all the angles in a triangle add up to 180, so we now have the equation x+2x+x-40=180. From here we solve to get 55 degrees for x, so angle 1 is 40 degrees, angle 2 is 110 (2 times 40) and the third angle is 15 (55-40).

What is 1/3 + 3/9 equals to

monitta

Answer:

2/3

Step-by-step explanation:

1/3 is the same as 3/9 (multiply 3 to both numerator and denominator) 3/9+3/9 is 6/9. 6/9 can be simplified by dividing 3 to both sides to get 2/3.
