Select the equation with the solution x = 25. The equation should have the variable on both sides, a decimal coefficient on the
Katyanochek1 [597]
It isn't A because there isn't a decimal in the hundredths.
It isn't B because it doesn't have a decimal coefficient on the left side: that means it could be C or D, to find out we should find what x is in C:
0.5x-5=0.15x+2
0.5x=0.15x+7
0.35x=7
Divide both sides by 7
0.05x=1
Now multiply both sides by 20:
x=20
That means it must be D, let's make sure:
0.6x-3=0.28x+5
0.6=0.28x+8
0.32x=8
Divide both sides by 8:
0.04x=1
Now multiply both sides by 25:
x=25
So the answer is D

Hope this helps :)

Find the missing side lengths. Leave your answers as radicals in simplest form.
steposvetlana [31]

The length of missing sides x = 5 units and y = 5 units.

<h3>What is Trigonometric ratios?</h3><h3>The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).</h3>

In ΔABC,

AB (Base) = y  ,      BC(Hypotenuse) = 5\sqrt{2}   ,       CA (perpendicular) = x

and ∠ABC = 45^0

Now,

tan 45^0  = perp. / base

1 = x /y

x= y .................(i)

again,

sin 45^0 = perp. / Hypo.

\frac{1}{\sqrt{2} } = \frac{x}{5\sqrt{2} }

x = 5

put in equation (i), we get

y = 5

Thus, the length of missing side of the given triangle is x = 5 units and y =  5 units.
