A rain barrel is full of water and used to water the garden. The rain barrel loses water at the rate 2.5 gallons of water per mi
soldier1979 [14.2K]
Answer: <span>y - 37.5 = 2.5 ( x - 7)

Explanation:

1) The point-slope form is has this form:

 y - y1 = m (x - x1)

Where m is the slope or rate of change and x1, y1 are the coordinates of the point.

2) you are told that the the rate of change of water (m) is 2.5

m = 2.5

3) The point is given by that after 7 min the rain barrel contains 37.5 gallons. This is:

x1 = 7
y1 = 37.5

</span>4) Replace those value in the point-slope model:

y - 37.5 = 2.5 ( x - 7)

That is the point-slope model or equation.

The length of atrain car is 50.6 feet. This is 5.8 feet less than 6 times the width. What is the width?
hichkok12 [17]
∗ l = 50.6 ft
∗ w = ?

∗ The length is 50.6 feet. The question is saying that 50.6 is 5.8 feet less than 6 times the width.

∗ 6w - 5.8 = 50.6

∗ 6w = 56.4

∗ w = 9.4

Now lets check.

∗ If the length is 5.8 feet less than 6 times the width, and we found 9.4 as the answer, then;
6 times 9.4 - 5.8 should equal 50.6

∗ 6 • 9.4 - 5.8 = l

∗ 56.4 - 5.8 = l

∗ 50.6 = l


⋆The width is 9.4 feet⋆

I need to know the answer I’m working on rational numubers
lesya [120]

Answer:

Fraction Form: \frac{11}{24}

Decimal Form: 0.4583

Step-by-step explanation:

Apply the fraction rule: \frac{-a}{b} = - \frac{a}{b}

\frac{-5}{12} = - \frac{5}{12}

- \frac{5}{12} + \frac{7}{8}

Least Common Multiple (LCM) of 12 and 8: 24

- \frac{5}{12} x  \frac{2}{2} = - \frac{10}{24} \\\\\frac{7}{8} x  \frac{3}{3} = \frac{21}{24} \\\\- \frac{10}{24} + \frac{21}{24}

Apply the fraction rule:

\frac{a}{c} + \frac{b}{c}= \frac{a + b}{c}\\\\\frac{-10 + 21}{24} \\\\-10 + 21 = 11\\\\\frac{11}{24}
