8/45
is already in the simplest form. It can be written as 0.177778 in decimal form (rounded to 6 decimal places).
Step-by-step explanation:
Answer:
5 ft
Step-by-step explanation:
If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.
× 3
can be rewritten as 
, so:
× 
The numerator & denominator share a common factor of 3, so:
5 ft is the final answer/perimeter.
hope this helps!
Answer:
Small number = 19
Larger no. = 3(19)+14 = 71
Step-by-step explanation:
x + 3x + 14 = 90
4x + 14 = 90
4x = 90 - 14
x = 76 / 4 = 19
Answer:
Step-by-step explanation:
y = -2/3 x multiply both sides the first equation by 6
6y = -4x Add 4x to both sides.
6y + 4x = 0
<u>-9y +4x = - 40 </u> Subtract the bottom equation
15y = - 40 Divide by 15
y = -40/15
y = - 2.7
======================
6y = -4x
6*(-2.67) = -4x
-16 = - 4x
x = - 16/-4
x = 4
Hi!
<h3>We need to isolate x on both sides, and whatever we do to the equation we have to do to both sides. </h3><h3>First, add 8 to both sides. </h3>
2x - 8 + 8 = -6 + 8
2x = 2
<h3>Divide by 2 on both sides</h3>
2x/2 = 2/2
<u>x = 1</u>
<h2>The answer is x = 1</h2>
Hope this helps! :)
