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

Write the equation of the line that is perpendicular to y=1/2x+3 and has a y-intercept of -4
Answer:
y=-2x-4
Step-by-step explanation:
When an equation is perpendicular, then it is the equation's inverse. The inverse of 1/2 is -2
The y-intercept is b in y=mx+b. In this equation, b=-4

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.

How many solutions can be found for the equation 5x + 3(x - 1) = 10x - 2x - 3?
None
One
Two
Infinitely many
Answer:
Infinitely many
Step-by-step explanation:
Equation: 5x + 3(x - 1) = 10x - 2x - 3
1) 5x + 3x - 3 = 10x - 2x - 3
2) 8x - 3 = 8x - 3
3) 8x = 8x
4) x = x
Based on this information, it seems that the best answer would be infinitely many solutions.
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.

Write the equation of a line in slope-intercept form with a slope of −13 and a y-intercept of 4 .
Answer:
y = -13x + 4
Step-by-step explanation:
You want to put it in the form y = mx + b where m is the slope and b is the y-intercept (For example, in the equation y = 2x + 3 the slope is 2 and the y-intercept is 3)
Since the slope is -13, m = -13.
Since the y-intercept is 4, b = 4.
This means the equation is y = -13x + 4

Question 1)
The expression:
11 more than one third of a number
Lets split this is up into parts to make it easier
"11", "more", "one third", "of a", "number"
Lets form the expression for each part,
"11" = 11
"more" = +
"one third" = 1/3
"of a" = *
"number" = n
That forms
11 + (1/3) * n or (1/3) * n + 11
Therefore the answer is D) (1/3)n + 11
