There are many ways to do this depending on the property you have to use:
If you use the distributive property, you need to distribute 3/4 to -10 and 2/5. Distribute means you will multiply it so your resulting equation will be this:
Before you can add, you need to first make them like terms because you cannot add unlike fractions. Get the LCD and form your new equation:
Now you can just add them together to get:
and then simplify your fraction:
or -
The whole fraction becomes negative because when you divide integers and of them is negative, the final answer will be negative.
Its A,,,,,,,,,,,,,,,,,,,,,,, <span>Jennifer has a string attached to the end of a buoy with extra string coiled on the bottom of the tank. She measures the length of the string from where it is attached to the buoy to the bottom of the tank as he adds more water to the tank. The length changes linearly as water is added. The table shows the collected data. What is the slope of the line that models the data?
</span>
Answer:
Equation of a line is y = mx + c
where m is the slope
c is the y intercept
From the graph using points ( 5 , - 4) and
( -5 , 2)
Slope = 2+4/ -5 - 5= 6/-10 = - 3/5
Equation of the line using point (5,-4) is
y + 4 = -3/5(x - 5)
y = -3/5x + 3 - 4
y = -3/5x - 1

Answer:
Correct answer: t₂ = 70 minutes
Step-by-step explanation:
Given:
t₁ = 28 minutes and t₁₂ = 20 minutes, t₂ = ?
The necessary equation for this situation is:
1/t₁ + 1/t₂ = 1/t₁₂ => 1/28 + 1/t₂ = 1/20 => (28 + t₂)/ 28 t₂ = 1/20 =>
28 t₂ = (28 + t₂) · 20 = 20 t₂ + 560 => 28 t₂ - 20 t₂ = 560 =>
8 t₂ = 560 => t₂ = 560/8 = 70 minutes
t₂ = 70 minutes
