C i just took the test hope this helps:-)
X equals 31 in the equation
Answer:
<h2>V=1/3 pie r^2h (Formula)</h2><h2>12×22/7=1/3×22/7×3^2×h</h2><h2>Eliminate 22/7</h2><h2>12=(9×h)/3</h2><h2>Make "h" the subject of the equation </h2><h2>h=36/9</h2><h2>h=4m</h2>
Answer:
The slope of the line m = 1
The equation of the straight line x -y -7=0
Step-by-step explanation:
<u><em>Explanation:-</em></u>
In the given graph
The points are ( 7,0) and ( 0, -7)
The slope of the line
The equation of the straight line passing through the point (7,0) and slope m=1
y - y₁ = m (x - x₁)
y - 0 = 1( x-7)
y = x -7
x - y -7=0
<u><em>Final answer:-</em></u>
The slope of the line m = 1
The equation of the straight line x -y -7=0
<u><em></em></u>
OK. Let's build this thing brick by brick,
one step at a time:
The number. . . . . . . . . . . . . . . . . . . . . . . N
==> Three times the number . . . . . . . . 3N
6 times the number. . . . . . . . . . . . . . . . 6N
==> 28 more than 6 times the number . 6N + 28
You said the three times the number is the same
as 28 more than 6 times the number.
So I can write
3N = 6N + 28
That's the equation.
Subtract 3N from each side: 0 = 3N + 28
Now subtract 28 from each side: -28 = 3N
Now divide each side by 3 : N = - 28/3 .
That number is kind of weird, but it's the ONLY number
that behaves according to the description in the question.
Three times the number . . . . . -28
6 times the number . . . . . . . . . -56
-28 is 28 more than -56. yay!
