Answer:
The lengths of the sides of a right triangle are
Longer leg = 0.4 units.
Shorter leg = 0.3 units.
Step-by-step explanation:
Given:
Hypotenuse = 0.5 units
Let the length of shorter leg of right triangle be x units then
According to the given condition,
length of longer leg will be (0.1 + x) units
Now,we know for a right triangle,by Pythagoras theorem we have

substituting the values we get

Applying
we get

which is a quadratic equation
dividing the equation throughout by two we get

Since x cannot be negative we take
x = 0.3 units
∴ Longer leg = x + 0.1
= 0.3+0.1
=0.4 units
So, the lengths of the sides of a right triangle are
Longer leg = 0.4 units.
Shorter leg = 0.3 units.
Answer: 
Step-by-step explanation:
Convert from decimal to fraction.
0.75 = 3/4. That is your answer.
X= 17/20 or, in decimal form, 0.85
Answer:
7x+3
Step-by-step explanation:
To simpfly, it would help by simply ignoring the variable (x) and just looking at the number before it, solving it like a regular math problem, from left to right.
9(x) - 2(x) = 7(x)
(-4)-(-7) = 3 --> since there's a minus sign in the middle subtracting the two numbers and one on the -7, the -7 becomes a positive 7. A negative times a negative is always positive so, it would technically be -4+7=3.
Put both of these two numbers together and you get your answer,
7x+3.
If you're having trouble with the part I explained the image might help. Read it from left to right. A negative # + a negative # = positive #, as seen by the first row.
