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 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.

Answer:
The rate of change is -300 meters per minute
Step-by-step explanation:
Here, we want to get the rate of change for the given situation
Firstly, we will need to collate the points
Let us have the points as:
(time, height)
The points are;
(10,4500) and (15,3000)
The formula for the slope m representing the average rate of change is;
m = (y2-y1)/(x2-x1)
m = (3000-4500)/(15-10) = -1500/5 = -300 meters/minutes

Answer:
90 - 37 will give a solid 53
Step-by-step explanation:
the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)
and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37
now we add angle degrees and sum and subtract one another,
90 - 37

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

y = 1/x+5 + 2
y = 1/x-2 + 2
y = 1/x+5 - 2
y= 1/x-5 - 2
Answer: I’m pretty sure it’s y=1/x+5 +2

The graph of Function [tex]y = \frac{1}{x-5}+2[/tex] is same as the graph of [tex]y = \frac{1}{x}[/tex]
What is a graph?"A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner."
What is a function?"Function, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)."
We have
[tex]y = \frac{1}{x}[/tex]

Mark is installing a mosaic tile backsplash and the shape of the tiles are shaped like regular octagons. Each tile has a length from side to side of 6 in. Once Mark gets a few pieces on the wall, he realized that there is a gap that the tiles do not cover. What size tile must he get to fill the gaps?
Answer:
square with sides of 6 in
Step-by-step explanation:
Tessellation is the arrangement of shapes in repeated patterns without gaps or overlapping.
Tessellation is usually done with regular polygons. Only three regular shapes can tessellate, these are equilateral triangle, regular square and regular hexagon. For other polygon to tessellate, more than one shape must be used. A octagon can be used to make tessellations if it is used together with a square.
Mark uses tiles with shape of octagon of sides 6 in. To fill the gaps, Mark have to uses a square with sides of 6 in

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.

Answer:
a = 15, b = -14
Step-by-step explanation:
From the question,
a/5 - b/2 = 10
Multiply all through by 10
(a/5)10 - (b/2)10 = 10×10
2a - 5b = 100...................... Equation 1
a - b = 29 ........................ Equation 2
Solving equation(1 ) and equation (2) simultaneously
using elimination method,
multiply equation (2) by 2.
2a - 2b = 58.................... Equation 3
Substract equation 3 from equation 1
2a - 2a -5b-(-2b) = 100-58
0 - 5b+2b = 42
-3b = 42
b = 42/-3
b = -14.
Substitute the value of b into equation 2
a - (-14) = 29
a +14 = 29
collect like terms
a = 29-14
a = 15.
Hence, a = 15, b =-14
