≈−2.071231518
Step-by-step explanation:
12.7−xx=8.41
Multiply x and x to get x
2
.
12.7−x
2
=8.41
Subtract 12.7 from both sides.
−x
2
=8.41−12.7
Subtract 12.7 from 8.41 to get −4.29.
−x
2
=−4.29
Divide both sides by −1.
x

−4.29
Expand

−4.29
≈4.29 by multiplying both numerator and the denominator by 100.

≈4.29 can be simplified to
100
429
=4.29 by removing the negative sign from both the numerator and the denominator.

since there are 12 inches in a foot all you do is divide 98 by 12 you get 8 feet and 2 inches.
Answer:
62
Step-by-step explanation:
<em>1st step: arrange your numbers in numerical order:</em>
60, 62, 64
<em>2nd step: count how many numbers you have:</em>
3 numbers
<em>3rd step: if odd, divide by 2 and round up to get the position of the median number:</em>
3 / 2 = 1.5 --> 2
<em>4th step: Go to the second number in the numerical order</em>
60, 62, 64
The first step for solving this equation is to collect the like terms with an r variable.
-r - 2 = -9
Now move the constant to the right side of the equation and then change its sign.
-r = -9 + 2
Calculate the sum on the right side of the equals sign.
-r = -7
Then lastly,, change the signs on both sides of the equation to find your final answer.
r = 7
This means that the correct answer to your question is going to be r = 7.
We can check this by putting 7 where r is in the equation. This means that in order to check this,, our equation will change to the following:
-8(7) - 2 + 7(7) = -9
We will first start checking this by multiplying the first two numbers together.
-56 - 2 + 7(7) = -9
Now multiply the 7 by the number in the parenthesis.
-56 - 2 + 49 = -9
Now use addition and subtraction rules to calculate the expression on the left side of the equals sign.
-9 = -9
This tells us that the equality us true because both sides of the equation are identical.
