Answer:

60

Step-by-step explanation:

We use unit rate function,

Let h be hours

Let b be baskets

2.5h = 150b

We divide both sides by 2.5

2.5h/2.5 = 150b/2.5

Which will give us

h = 60

<h2>Solving Inequalities</h2><h3>Answer:</h3>

(-\infty,-8]

<h3>Step-by-step explanation:</h3>

-2x +7 \geqslant 23 \\ -2x +7 -7 \geqslant 23 -7 \\ -2x \geqslant 16 \\ \frac{-2x}{-2} \leqslant \frac{16}{-2} \\ x \leqslant -8

The values of x has to be less than or equal to 8 so x \in (-\infty,-8]

The length of one side of a triangle is 2 feet less than three times the length of its second side. The length of the third side
Zanzabum

Using a system of equations, it is found that the lengths of the sides of the triangle are given as follows:

0.91 feet, 0.73 feet, 1.23 feet.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are the lengths, given by x, y and z.

The length of one side of a triangle is 2 feet less than three times the length of its second side, hence:

y = 3x - 2.

The length of the third side is 3/4 of the sum of the lengths of the first two sides, hence:

z = \frac{3(x + y)}{4} = \frac{3(4x - 2)}{4}

The perimeter of the triangle is 17.5 feet, hence:

x + y + z = 17.5

x + 3x - 2 + \frac{3(4x - 2)}{4} = 17.5

4x + \frac{3(4x - 2)}{4} = 19.5

16x + 12x = 25.5

x = 25.5/28

x = 0.91.

Then the other sides are:

  • y = 3x - 2 = 3(0.91) - 2 = 0.73 feet.
  • z = \frac{3(4 x 0.91 - 2)}{4} = 1.23 feet

3x + 4y = -5 
-3x              -3x

4y= -3x -5
/4      /4

y= -3/4x-5/4

3x + 3y = -2
-3x             -3x

3y = -3x-2
