0.6y + 0.8 = 0.28y + 1.12
gavmur [86]

Answer:

<h2>y = 1</h2>

Step-by-step explanation:

0.6y + 0.8 = 0.28y + 1.12

Move the variable to L.H.S and change its sign:

0.6y - 0.28y + 0.8 =1.12

Move the constant to R.H.S and change its sign:

0.6y - 0.28y = 1.12 - 0.8

Calculate

0.32y = 0.32

Divide both sides of the equation by 0.32

\frac{0.32y}{0.32}  =  \frac{0.32}{0.32}

Calculate

y  = 1

Hope this helps...

Good luck on your assignment..

In-s [12.5K]

Given

The three sides are given 24, 30 and 18.

Explanation

To find the triangle is acute, obtuse or right triangle.

To determine whether the triangle is acute, right, or obtuse.add the squares of the two smaller sides, and compare the sum to the square of the largest side. Since this sum is greater, the triangle is acute.

A

If the sum of the squares of the two smaller sides is equal to the square of the largest side , then it is right triangle.

Now c.

\begin{gathered} 30^2=24^2+18^2 \\ 900=576+324 \\ 900=900 \end{gathered}

Answer

Hence the sum of the squares of the two smaller sides is equal to the square of the largest side , then it is right triangle.

The correct option is A.
