6 × n + 15 = -42
6n + 15 = -42
6n = -42 - 15
6n = -57
n = -57/6
n = -19/3

b + 3/2b + b + 45 + 2b - 5 + 90 = 540
b + 1.5b + b + 45 + 2b - 5 + 90 = 540
5.5b + 130 = 540
5.5b = 540 - 130
5.5b = 410
b = 410/5.5
b = 74.5
Angles are
b = 74.5
1.5(74.5) = 111.75
74.5 + 45 = 119.5
2(74.5) - 5 = 144

For each problem you need to make sure that the angles are the same.
So x + 22 = 90
x = 90 -22 = 68 degree

In the diagram, P, Q, R, S, and T are collinear. PT=54 QT= 42 QS= 31 and RS= 17. Then find PQ, QR, ST, PS, PR, RT
Answers
If the points like P, Q, R, S and T are collinear they will follow the segment addition postulate.
Length of segments will be,
PQ = 12 units
QR = 14 units
ST = 11 units
PS = 43 units
PR = 26 units
RT = 28 units
It's given in the question,
P, Q, R, S, T are collinear.And the lengths of different segments are,
PT = 54QT = 42QS = 31RS = 17By segment addition postulate,
PQ + QT = PT
PQ = PT - QT
PQ = 54 - 42
= 12 units
QR + RS = QS
QR = QS - RS
= 31 - 17 = 14 units
ST = QT - QS
= 42 - 31 = 11 units
PS = PT - ST
= 54 - 11
= 43 units
PQ + QR = PR
12 + 14 = PR
PR = 26 units
RS + ST = RT
17 + 11 = RT
RT = 28 units

Write 0.24 repeating as a fraction in simplest form.
Answers
Answer:
24/100
Step-by-step explanation:
Simplest fractional form of 0.24 repeating will be 6/25.
Fractions: A number in p/q form where q must not be zero is termed as fractions.
Given, that number 0.24 is repeating in nature.
So, to convert 0.24 from decimal to fraction .
Remove the decimal by dividing the whole number by 100 as decimal is two places behind.
0.24 = [tex]\frac{24}{100}[/tex]
Simplify the fractional form,
GCF of 24 and 100 = 4
So divide 24 and 100 by 4,
Therefore the required fraction is ,

Answers
Answer:
I)
[tex]\displaystyle A + B + C = 2x^2 + 4xy + 2[/tex]
II)
[tex]\displaystyle A - B + C = 6x^2 -8xy[/tex]
III)
[tex]\displaystyle A + B - C= -4x^2 + 10xy -12[/tex]
Step-by-step explanation:
We are given the three equations:
[tex]\displaystyle A = x^2 + xy -6,\, B = 6xy - 2x^2 +1 \text{ and } C = 3x^2 + 7 -3xy[/tex]
I)
We want to find:
[tex]\displaystyle A + B + C[/tex]
Substitute:
[tex]\displaystyle = (x^2 + xy - 6) + (6xy -2x^2 + 1) + (3x^2 + 7 -3xy)[/tex]
Rewrite:
[tex]\displaystyle = (x^2 + 3x^2 - 2x^2) + (xy + 6xy - 3xy) + (-6 + 1 + 7)[/tex]
And combine like terms. Hence:
[tex]\displaystyle A + B + C = 2x^2 + 4xy + 2[/tex]
II)
We want to find:
[tex]\displaystyle A - B + C[/tex]
Likewise, substitute:
[tex]\displaystyle = (x^2 + xy - 6) - (6xy - 2x^2 + 1) + (3x^2 + 7 - 3xy)[/tex]
Distribute:
[tex]\displaystyle = (x^2 + xy - 6) + (-6xy +2x^2 - 1) + (3x^2 + 7 - 3xy)[/tex]
Rewrite:
[tex]\displaystyle = (x^2 + 2x^2 +3x^2) + (xy - 6xy -3xy) + (-6 -1 + 7 )[/tex]
And combine like terms. Hence:
[tex]\displaystyle A - B + C = 6x^2 -8xy[/tex]
III)
We want to find:
[tex]\displaystyle A + B - C[/tex]
Substitute:
[tex]\displaystyle = (x^2 + xy - 6) + (6xy - 2x^2 + 1) - (3x^2 + 7 - 3xy)[/tex]
Distribute:
[tex]\displaystyle = (x^2 + xy - 6) + (6xy - 2x^2 + 1) + (-3x^2 - 7 + 3xy)[/tex]
Rewrite:
[tex]\displaystyle = (x^2 - 2x^2 - 3x^2) + (xy +6xy +3xy) + (-6 +1 - 7)[/tex]
And combine like terms. Hence:
[tex]\displaystyle A + B - C= -4x^2 + 10xy -12[/tex]
