Answer:
[tex] \sqrt{\frac{9}{4}} [/tex] < [tex] \frac{5}{3} [/tex] < [tex] \sqrt{5} [/tex] < 2.5
Step-by-step explanation:
Given the following numbers, [tex] \sqrt{\frac{9}{4}}, \sqrt{5}, 2.5, and, \frac{5}{3} [/tex], let's express each as whole or decimal numbers, to find out the least to the greatest.
[tex] \sqrt{\frac{9}{4}} = \frac{\sqrt{9}}{\sqrt{4}} [/tex]
[tex] \frac{3}{2} = 1.5 [/tex]
[tex] \sqrt{5} [/tex] ≈ 2.2
2.5 (already in decimal form)
[tex] \frac{5}{3} [/tex] ≈ 1.7
From the least to the greatest, we have:
[tex] \sqrt{\frac{9}{4}} [/tex] < [tex] \frac{5}{3} [/tex] < [tex] \sqrt{5} [/tex] < 2.5

Answer:
Answer: Option D.
Step-by-step explanation:
Hey there!!
Here, To find the equation of a st.line passing through point (3,1) is :
[tex](y - 1) = m1(x - 3)[/tex]
It is the first equation.
Given, Another equation is:
[tex]y = \frac{2}{3} x + 1[/tex]
It is 2nd equation.
Comparing the 2nd equation with y = mx+c we get,
Slope (m2) = 2/3.
As per the condition of parallel lines,
m1 = m2 = 2/3.
Putting, the value of m1 in equation 1st we get,
[tex](y - 1) = \frac{2}{3} (x - 3)[/tex]
or, 3 (y-1) = 2(x-3)
or, 3y - 3 = 2x - 6
[tex]y = \frac{2x - 6 + 3}{3} [/tex]
[tex]y = \frac{2}{3} x - 1[/tex]
Diving-3/3 = -1.
Therefore, y = 2/3 x - 1 is the required equation.

What is the absolute value of |5+8a|=53?
Answer:
a = 6 or a = -58/8
Step-by-step explanation:
I think you meant to ask us to solve for a.
There are two cases to solve for:
5 + 8a = 53 or -(5 + 8a) = 53
8a = 48 or 5 + 8a = -53
a = 6 or 8a = -58
a = 6 or a = -58/8
_ - 72 = 62 - 53

Which properties can be used to solve 7y − 15 = −29? Select all that apply. A. Identity Property of Multiplication
B. Addition Property of Equality
C. Distributive Property
D. Inverse Property of Multiplication
E. Commutative Property of Addition
Answer:
A and E
Step-by-step explanation:
Other 2 wouldn't make sense
Only definite of A
Addition Property of Equality ----If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal.
Commutative property of addition- changing the order of the numbers we are adding, does not change the sum. Here's an example of how the sum does NOT change, even if the order is changed
The properties that can be used to solve 7y - 15 = -29 are
Addition property of equality and inverse property of multiplication.
Given equation is 7y - 15 = -29.
We will solve for y and see which of the given following properties are applied.
What is addition property of equality and the inverse property of multiplication?Addition property of equality
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal.
Inverse property of multiplication
It states that every non-zero x multiplied with 1/x will equal 1.
Solve for y.
7y - 15 = -29
We will add 17 on both sides of the equation.
7y - 15 + 15 = -29 + 15
7y = -14
Now, multiply 1/7 into both sides of the equation.
7y / 7 = -14 / 7
y = -2
While solving for y we see that we have to use the addition property of equality and inverse property of multiplication.

6. Give the slope of each line. Also, state if the lines are parallel (yes or no).
Hint: rewrite to slope intercept form.
AB: 2y + 2x = 8 and CD: y + x = 2
Slope of line AB:
Slope of line CD:
Are the lines parallel (yes or no):
Step-by-step explanation:
Hey there!!
Let me simply clear you.
Given,
AB: 2y+2x =8.
Let's take the equation in slope intercept form.
2y = -2x +8
[tex]y = \frac{ - 2x}{2} + \frac{8}{2} [/tex]
[tex]y = - 1x + 4[/tex]
Comparing the equation with y= mx+c, we get;
Therefore, slope of AB is -1.
Now,
Again, the another equation is,
y + x = 2
y = -x+2
Comparing, the equation with y = mx + c.
Therefore, slope of CD = -1
For parallel lines, m1=m2.
slope of AB (m1) = -1
slope of CD(m2)= -1
As m1= m2 {True}.
Therefore, They are parallel to eachother.

Two angles form a linear pair. the measure of one angles is 15° less than 2/3 the measure of the other angle. Write and solve an algebraic equation to find the measure of each angle. I need help! someone plz help me!
Answer:
First angle = 117 degrees.
Second angle = 63 degrees.
Step-by-step explanation:
If two angles are a linear pair, then their measures must add up to 180°. A straight line has a measure of 180°.
If we let one angle = x, then the other angle is (2/3)x - 15
Now we can form the following equation:
x + (2/3)x - 15 = 180
(5/3)x = 195
5x = 585
x = 117
Therefore, one angle is 117 degrees, and the other angle is (2/3 * 117) - 15 = 78 - 15 = 63 degrees.

Brian is traveling at a rate of 72.0 meters/second. What speed would he be traveling in miles/hour?
Answer:
we know that, 1miles/hour = 0.45m/s
or, 1meters/second = 1/0.45
1m/s = 2.22222222222

Then,
72.0 meters/second = 72.0*2.22222222222
=160 miles per hour.
3 (n - 5) - (6 -2n) = 4n
Answer:
21
Step-by-step explanation:
3n - 15 - 6 + 2n = 4n
3 n + 2n = 4n + 15 + 6
5 n - 4n = 15 + 6
n = 21
Answer:
n = 21
Step-by-step explanation:
Use distributive rule: a(b + c) = a*b + a*c
3(n -5) - (6 - 2n) = 4n
3*n - 3*5 + 6*(-1) - 2n *(-1) = 4n
3n - 15 - 6 + 2n = 4n {add like term in LHS}
3n + 2n - 15 - 6 = 4n
5n - 21 = 4n {add 21 to both sides}
5n -21 + 21 = 4n +21
5n = 4n + 21 {subtract 4n from both sides}
5n - 4n = 4n -4n +21
n = 21
Which of the following is a correct proportion?
А. 2/3 = 4/9
B. 5/7 = 10/11
C. 4/6 = 8/12
D. 3/4 = 12/9
First, we'll solve A.
2 x2 = 4
3 x2 = 9
3x2=6, not 9.
So it is not A.
5 x2 = 10
7 x2 = 11
7x2=14, not 11.
So B. is out too.
It isn't D. because 12/9 is improper and 3/4 isn't.
So C. is left.
4 x2 = 8
6 x2 = 12
hope it helps!
===============================================
Explanation:
Let's go through the answer choices
-----------
Choice A.
Assume that the given equation here is correct. If so, then we can cross multiply to get
2/3 = 4/9
2*9 = 3*4
18 = 12
The last equation is false, so the first equation is also false. Choice A is not the answer.
-------------
Choice B.
We could do the similar trick as with choice A, but I'll use another method.
Use your calculator to find that
5/7 = 0.714 approx
10/11 = 0.909 approx
We get different decimal values for each fraction, so there's no way the two sides are the same. Choice B is crossed off the list.
-------------
Choice C.
I'll use another method here. Note how the denominators are 6 and 12, and how 6*2 = 12. If we multiply top and bottom of 4/6 by 2, then
(4/6)*(2/2) = (4*2)/(6*2) = 8/12
meaning that 4/6 = 8/12 is a true equation. We can see it through cross multiplication
4/6 = 8/12
4*12 = 6*8
48 = 48
or we could use our calculator to find that
4/6 = 0.667 approx
8/12 = 0.667 approx
Another calculator trick you can use is type in "4/6 - 8/12" without quotes and you should get 0 (or very close to it) as a result. This is using the idea that if x = y, then x-y = 0.
Choice C is the answer
----------------
Choice D.
Since we found the answer, we technically don't need to check choice D. But let's do so anyway.
Right off the bat, we know that 3/4 is less than one, while 12/9 is greater than one. So there's no way 3/4 = 12/9 could be true.
In the diagram below, which distances would need to be the same in order for point A to be on the bisector of angle W? Explain why this is true.
Answer:
PA = XA
Step-by-step explanation:
Construction of an angle bisector,
1). Mark an arc from point W with the help of a compass which intersect lines WS and WZ at the points P and X respectively.
2). Marc two arcs of the same length form the points P and X which intersect each other at a point A.
3). Joint the points A and W.
Thus AW will be the angle bisector of angle PWX where PA = XA.
Therefore, distances PA and XA will be equal in measure.
