I need help working this algebra 2 question 3/4 - 5/6R = 7/10
Brilliant_brown [7]

Answer:

R = 3/50

Step-by-step explanation:

If you are trying to solve for a variable,

1. Simplify both sides of the equation:

3/4 - 5/6R = 7/10 will now be (-5/6r) + 3/4 = 7/10

2. Add  -3/4 from both sides of the equation:

(-3/4) + 3/4 = 0 and (-3/4) - 7/10 = -1/20.

You will be left with: -5/6r = -1/20.

3. Divide both sides by (-5/6).

(-5/6r) / -5/6 = 1R or just R. (-1/20) / -5/6 = 3/50

You are left with the answer:

R = 3/50

<em>I hope this helps!</em>

6r + 7 = 13 + 7r what is r
kumpel [21]

Answer:

6r+7=13+7r

6r+7=7r+13

6r+7−7r=7r+13−7r

−r+7=13

−r+7−7=13−7

−r=6

\frac{-r}{-1} = \frac{6}{-1}

r=−6

A rock is thrown up from the ground at a velocity of 84 feet per second. The formula h = -16t2 + 84t gives the rock's height in
kenny6666 [7]

Answer:

h = 110.24 m

Step-by-step explanation:

It is given that,

A rock is thrown up from the ground at a velocity of 84 feet per second. The formula h = -16t^2 + 84t gives the rock's height in feet after t second.

We need to find the maximum height of the rock. For maximum height put \dfrac{dh}{dt}=0

So,

\dfrac{d( -16t^2 + 84t)}{dt}=0\\\\-32t+84=0\\\\t=\dfrac{84}{32}\\\\t=2.62\ s

Put t = 2.62 s in the equation of height. So,

h = -16(2.62)^2 + 84(2.62)\\\\h=110.24\ m

So, the maximum height of the rock is 110.24 m.

Please help me on this question (7th grade math) show your work
lakkis [162]

You can take two of the x and y on the table to find the slope:

y2 - y1 / x2 - x1

Lets use (3, 12) and (4, 15)

15 - 12 / 4 - 3

3/1

The slope is 3

Now you can use the point-slope formula to find the equation: y - y1 = m(x - x1)

y - 9 = 3(x - 2)

y - 9 = 3x -6

y = 3x + 3

So you are correct with choice B.

Hope this helped! Mark as Brainliest Please! :)))
