Select why this equation is true or false without adding.
52 + 27 = 49 + 24
A. )True because, if we compare 52 to 27 and 49 to 24 they are exactly the same
distance apart on a number line. They just have different starting and ending points.
B.). True because, both 52-27 and 49-24 result in the same answer of 25.
C). False because, if 3 is subtracted from 52 to get 49, then, 49 and 27 more would not
equal 49 and 24 more. Putting together two larger numbers is not the same as
putting together two smaller numbers.
D). False because 52 + 27 does not equal 49
.
False because if 3 is subtracted from 52, then 49 and 27 more would not equal 49 and 24 more. Putting together two larger numbers is not the same as putting together two smaller numbers.
=======================================================
Explanation:
If we break up 52 into 49+3, then we can do the following rearrangement.
52 + 27 = 49 + 24
49 + 3 + 27 = 49 + 24
3 + (49+27) = 49 + 24
Notice that the 49+27 on the left is clearly larger than 49+24 on the right, mainly due to the 27 being larger than 24.
Then adding on 3 more means that the left side gets even larger.
So without having to add either side and simplify fully, we can see that the left side is larger than the right side. There's no way the two sides are the same number.
----------
Perhaps another quick way is to simply look at the units digits.
The 2 and 7 from 52 and 27 add to 2+7 = 9
The 9 and 4 from 49 and 24 add to 9+4 = 13 and we only care about the 3
The mismatch of the 9 and 3 is more evidence that the two sides aren't the same number.

WorkOut Fitness Center gym charges $150 per year for membership plus $5 per visit. Jack went to the gym 135 time last year.
How much did he spend?
Answer:
$825
Step-by-step explanation:
You have to create an equation.
Your equation is x = 150 + 135y, "x" represents the total amount of money Jack spent that year, and "y" represents the 5 dollars that you have to pay every time you have to visit the gym and Jack went to the gym 135 times, so you have to multiply 135 and 5 which is 675.
We have broken the equation down to x = 150 + 675, so you just have to do 150 + 675 which is 825.
Jack spent $825 last year.

The equation of a circle in the xy-plane is shown
above. What is the diameter of the circle?
The diameter of the equation of a circle in the xy-plane as shown is 26 units.
The standard form for finding the equation of a circle is expressed as:
[tex]x^2 + y^2 +2gx + 2fy +C= 0[/tex]
For us to get the diameter of the circle, we need to get the radius of the circle first calculated as shown:
[tex]r=\sqrt{g^2+f^2-C}[/tex]
Given the equation of the circle expressed as [tex]x^2 + y^2 - 6x + 8y = 144[/tex]
Compare with the general formula:
2gx = -6x
g = -6/2
g = -3
Similarly;
2fy = 8y
2f = 8
f = 4
C = -144
Substitute into the formula for calculating the radius;
[tex]r=\sqrt{(-3}^2+4^2-(-144)\\r=\sqrt{9+16+144}\\r=\sqrt{169}\\r=13units[/tex]
Get the diameter of the circle
d = 2r
d = 2(13)
d = 26 units
Hence the diameter of the equation of a circle in the xy-plane as shown is 26 units.

What is 1 + 1 + 2 - 7 + 4? Take your answer and make it x. X + 4 - 2 + X. What is the final answer?
Answer:
(b)
Step-by-step explanation:
1. In a group of cows and chickens, the number of legs was 14 more than twice the number of heads. The number of cows was:
(a) 5, (b) 7, (c) 10, (d) 12, (e) 14
Solution:
Let the number of cows be x and their legs be 4x.
Let the number of chicken be y and their legs be 2x.
Total number of legs = 4x + 2y.
Total number of heads = x + y.
The number of legs was 14 more than twice the number of heads.
Therefore, 2 × (x + y) + 14 = 4x + 2y.
or, 2x + 2y + 14 = 4x + 2y.
or, 2x + 14 = 4x [subtracting 2y from both sides].
or, 14 = 4x – 2x [subtracting 2x from both sides].
or, 14 = 2x.
or, x = 7 [dividing by 2 on both sides].
Therefore, the number of cows = 7.

What are the values of s and t?
Answer:
w = 48
x = 66
Step-by-step explanation:
The triangle in your picture is an isoceles triangle, meaning that IH = JH.
Which means that angle I is equal to angle J or x = 66.
Now you just have to add up all three angles to 180 degrees.
66 + 66 + w = 180
132 + w = 180
w = 48

If c (x) = 5 Over x minus 2 and d(x) = x + 3, what is the domain of (cd)(x)?
The domain of the function (cd)(x) will be all real values of x except x = 2.
Step-by-step explanation:
The two functions are c(x)=
[tex] \frac{5}{ \times - 2} [/tex]
and d(x) = x + 3
So, (cd)(x) =
[tex]( \frac{5}{ \times - 2} )( \times + 3) = 5\frac{( \times + 3)}{ \times - 2} [/tex]
Therefore, the domain of the function (cd)(x) will be all real values of x except x = 2. (Answer)

P(x) = (0.09)
Which statement best describes the graph of p(x) and g(x)? (1 point)
The graphs will both have their y-intercept equal to 1.
The graphs will both have their y-intercept equal to 0.09.
The graph of p(x) will eventually exceed the graph of g(x).
The graph of g(x) will eventually exceed the graph of p(x).
Will give brainliest :)
Assuming that you actually mean that: p(x) = (0.09)^x, then the correct answer would be:
"The graph of g(x) will eventually exceed the graph of p(x)."
This is because the function p(x) is an exponential decay function, and the function g(x) increases at a constant rate. Although p(x) would be greater at first, as the value of x increases, then g(x) will slowly catch up.
pls answer my module i give 10 pts for this
Step-by-step explanation:
what is the problem here you don't understand ?
you understand the words "equality" and "inequality" ?
this is all about the question, if something is equal to something else or not - meaning of they are the same or at least the same size.
an expression without an equal ("=") or unequal sign ("<", ">", ">=", "<=", "<>" - if you don't understand these symbols, please ask, they are simply basic keyboard symbols for the scientific symbols) is not any form of that - no equality, and no inequality.
so,
1. is NOT
2. is NOT because it has an equality symbol
3. is a quadratic inequality (when doing the multiplication of both bracket terms, there will be an x×x=x² part) - it has a ">" (greater) symbol
4. is a quadratic inequality (there is a x² term as highest power of x included) - it has a "<=" (smaller or equal) symbol
5. is a quadratic inequality (there is a x² term as highest power of x included) - it has a ">" (greater) symbol
The sum of four consecutive odd integers is 328. What are the integers? (show your work)
Answer:
79, 81, 83, and 85
Step-by-step explanation:
x = 1st integer
x+2 = 2nd
x+4 = 3rd
x+6 = 4th
328 = sum
x+x+2+x+4+x+6 = 328
328/4 = 82
The 4 integers are the 2 odd integers on either side of 82 and closest to 82
That would be 79, 81, 83, and 85.
79 + 81 + 83 + 85 = 328

Consider the figure below where MN is parallel to PQ, angle PTS is equal to (19x +5) and angle NST is equal to (17x +15), determine angle MSR and angle STQ
From the figure shown where MN is parallel to PQ:
m<MSR = 100°
m<STQ = 80°
By carefully observing the figure shown:
<MSR is vertically opposite to <NST
Vertically opposite angles are equal
m<NST = (17x + 15)
<NST is alternative to <PTS
Alternative angles are equal
Therefore, m<NST = m<PTS
m<NST = 17x + 15
m<PTS = 19x + 5
17x + 15 = 19x + 5
19x - 17x = 15 - 5
2x = 10
x = 10/2
x = 5
m<NST = 17x + 15
m<NST = 17(5) + 15
m<NST = 100°
Since m<MSR = m<NST
m<MSR = 100°
m<PTS = 19x + 5
m<PTS = 19(5) + 5
m<PTS = 100°
m<PTS + m<STQ = 180° (Sum of angles on a straight line)
100 + m<STQ = 180
m<STQ = 180 - 100
m<STQ = 80°
From the figure shown where MN is parallel to PQ:
m<MSR = 100°
m<STQ = 80°
