Solve the system using elimination
Answer:
x = 5
y = 1/4
Step-by-step explanation:
Let a = 1/x
b = 1/y
Then the equations are
(1) 10a - 4b = -14 and (2) 5a + 8b = 33 Multiply equation (2) by -2
-10a - 16b = -66
-20b = - 80
b = 4 5a + 8(4) = 33
5a + 32 = 33
5a = 1
a = 1/5
a = 1/x = 1/(1/5) x = 5
b = 1/y = 4 y = 1/4

If using the method of completing the square to solve the quadratic equation x2 - 6x – 7 = 0, which number would have to be added to "complete the square"?
Answer:
(-3)^2
Step-by-step explanation:
You add 7 on both sides, giving you x^2 - 6x = 7
Then, take half of b, and square it. Giving you x^2 - 6x +(-3)^2 = 7
The answer will be (-3)^2 for this question, but this is not the full solution.
Hope this helped. Good luck on the rest!

Answer:
1.411.99Step-by-step explanation:
The Pythagorean theorem (see Hint) tells you the length of the hypotenuse (c) is ...
c² = 1² + 1² = 2
c = √2 ≈ 1.4142136 . . . units
The estimated value of the length of the hypotenuse is 1.41 units.
__
Of course the shaded square will have an area that is the square of that value:
area = s² ≈ 1.41² ≈ 1.99 . . . . . rounded to hundredths
The estimated area of the square is 1.99 square units.
__
Additional comment
Of course, we don't have to estimate. We can use the exact value of the side length to determine the shaded square has an area of ...
area = s² = (√2)² = 2 . . . . exactly
We can also get there by recognizing that the lengths of 1 represent half the length of each of the diagonals of the square. That is, the square's diagonals are both of length 2. The area is half their product, so is (1/2)(2·2) = 2 square units.

Kenya is solving the equation 5 3/4 - 1/6x = 4 1/2. She gets to 1 1/4 = 1/6x. Is this a valid way to solve the equation? answer asap please
Answer:
15/2
Step-by-step explanation:
5 3/4 - 1/6x = 4 1/2
move the variable to it's own side.
5 3/4 - 4 1/2 = 1/6x
change the subtracting side to have common denominators
5 3/4 - 4 2/4 = 1/6x
1 1/4 = 1/6 x
divide both sides by 1/6, same thing as multiplying both sides by 6 (reciprocal)
30/4 = x
reduce: 15/2 = x
The value of x should be 15/2.
Calculation of the value of x:Since
5 3/4 - 1/6x = 4 1/2
So, it can be like
5 3/4 - 4 1/2 = 1/6x
Now
5 3/4 - 4 2/4 = 1/6x
1 1/4 = 1/6 x
Now we have to divide both sides by 1/6
So,
30/4 = x
x = 15/2

How do you do 4 divided by 0.8 in place value
Answer:
5
Step-by-step explanation:
because that is the correct answer
4 divided by 0.8 is equal to 5.
To divide 4 by 0.8 using place value, you can follow these way
Convert the decimal divisor, 0.8, into a whole number by multiplying both the tip and the divisor by a power of 10.
Since there's only one decimal place in0.8, you can multiply both figures by 10 to exclude the decimal
0.4 x 10 = 40( multiplying the tip by 10)
0.8 x 10 = 8( multiplying the divisor by 10)
Now we've the division problem as 40 divided by 8.
Divide the converted tip by the converted divisor
= 40 ÷ 8
= 5
Thus, 4 divided by 0.8 is equal to 5.

Answer:
AB ≈ 1095 yards
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
AB² + BS² = AS²
AB² + 1300² = 1700²
AB² + 1690000 = 2890000 ( subtract 1690000 from both sides )
AB² = 1200000 ( take the square root of both sides )
AB = [tex]\sqrt{1200000}[/tex] ≈ 1095 yd ( to the nearest yard )
Which ratio is equivalent to 3:18?
A 6:21
B 5:20
( 7:42
D 12:2
The ratio is equivalent to 3:18 is 7:42.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
Ratio = 3:18
= 1: 6
1. 6:21
= 3:7
2. 5:20
= 1:4
3. 7:42
= 1:6
4. 12:2
= 6:1
Hence, the ratio is equivalent to 3:18 is 7:42.
