First we need to find how far away the base of the ladder is from what it is leaning against. The ramp is the hypotenuse and the height from the ground in a leg. Let’s use Pythagorean’s theorem.

a^2 + b^2 = c^2

Substitute

a^2 + (5)^2 = (20)^2

Solve for a^2

a^2 = (20)^2 - (5)^2

Solve for a

a = 5 √15

The slope will be rise over run

5/5 √15 = √15/15 or 0.258…

Find the equation equivalent to 2x=4 which is a multiple of 3

stich3 [128]

we have to find equation similar to

$2x=4$

Firstly , we can divide both sides by 2

$\frac{2x}{2} =\frac{4}{2}$

$x=2$

now, we can multiply both sides by 3

$3*x=3*2$

we get

$3x=6$ ............Answer

How do you do this problem 1/4 +4x/5=11/20?

Nutka1998 [239]

$\frac{1}{4}+\frac{4}{5}x=\frac{11}{20}\\\\\frac{4}{5}x=\frac{11}{20}-\frac{1}{4}\\\\\frac{4}{5}x=\frac{11}{20}-\frac{5}{20}\\\\\frac{4}{5}x=\frac{6}{20}\ \ \ \ \ \ \ |\cdot\frac{5}{4}\\\\x=\frac{30}{80}=\frac{3}{8}$
