Answer:
138
Step-by-step explanation:
G + H = 180 {G, H are linear pair}
12x + 6 + 4x - 2 = 180
12x + 4x + 6 - 2 = 180
16x + 4 = 180
16x = 180 - 4
16x = 176
x = 176/16
x = 11
G = 12x + 6
= 12*11 + 6
= 132 + 6
= 138

Jason wants to solve the following system using the elimination method:
x + 3y = 10
2x + y = 5
What number should the equation 2x + y = 5 be multiplied by to eliminate y?
a. 2
b. -3
c. -2
d. 3
Answers
Answer:
No single Correct answer. Both b and d will work
Step-by-step explanation:
You want to get rid of y.
The first equation has a 3 in front of the y
Therefore you would have to multiply the second equation by 3 or - 3
If you use -3 you would add the two equations
If you use 3 you would subtract the two equations.
It is either b or d. Both will give you the same answer.
- Three
x + 3y = 10
-6x - 3y = - 15 Add
-5x = - 5 Divide by - 5
x = -5/-5
x = 1
+ Three
x + 3y = 10
6x + 3y = 15 Subtract
-5x = - 5
x = -5/-5
x = 1 Same thing.

Answer:
20, 31, 42, 53, 64, 75, 86, 97
Step-by-step explanation:
The difference of 18 means the difference of digits is 18/9 = 2. Since the number you seek is the larger number, the 10s digit will be 2 more than the 1s digit. Possible numbers are ...
20, 31, 42, 53, 64, 75, 86, 97
_____
If t and o are the tens and ones digits respectively, the relation you seek is ...
(10t +o) -(10o +t) = 18
9(t -o) = 18
t - o = 2 . . . . as above
Since both t and o must be single digits, the minimum will be t=2, o=0, and the maximum will be t=9, o=7.
Answer:
10a+b=10b+a-18
9a+9b = -18
9(a+b) = -18
a+b = 18/9
a + b =2

Find the regression equation, letting the first variable be the predictor (x) variable. Find the best predicted Nobel Laureate rate for a country that has 78.8 Internet users per 100 people. How does it compare to the country's actual Nobel Laureate rate of 2 per 10 million people
Answers
The table is missing, so i have attached it.
Answer:
Regression equation is;
y = 0.2028x - 8.443
The predicted value is not at all close to the actual novel rate
Step-by-step explanation:
The internet users will be the x-values while the novel laureates will be the y-values.
Thus, sum of x values is;
Σx = 79.5 + 79.6 + 56.8 + 67.6 + 77.9 + 38.3 = 399.7
Sum of y values is;
Σy = 5.5 + 9 + 3.3 + 1.7 + 10.8 + 0.1
Σy = 30.4
Σx² = 79.5² + 79.6² + 56.8² + 67.6² + 77.9² + 38.3²
Σx² = 27987.71
Σy² = 5.5² + 9² + 3.3² + 1.7² + 10.8² + 0.1²
Σy² = 241.68
Σxy = (79.5 × 5.5) + (79.6 × 9) + (56.8 × 3.3) + (67.6 × 1.7) + (77.9 × 10.8) + (38.3 × 0.1)
Σxy = 2301.16
The regression line will be;
y = b1(x) + b0
b1 is expressed as;
b1 = [nΣxy - (Σx • Σy)]/[nΣx² - (Σx)²]
Where n is number of given data which is n = 6.
Thus;
b1 = [(6 × 2301.16) - (399.7 × 30.4)]/[(6 × 27987.71) - (399.7)²]
b1 = 1656.08/8166.17
b1 = 0.2028
b0 is expressed as;
b0 = [(Σy • Σx²) - (Σx • Σxy)]/[nΣx² - (Σx)²]
b0 = [(30.4 × 27987.71) - (399.7 × 2301.16)]/[(6 × 27987.71) - (399.7)²]
b0 = -68947.268/8166.17
b0 = -8.443
Thus, regression equation is;
y = 0.2028x + (-8.443)
y = 0.2028x - 8.443
Best predicted value is given as;
y¯ = (Σy)/n
y¯ = 30.4/6
y¯ = 5.067 per 10 million people.
The predicted value is far greater than the actual value of 2 per 10 million people.
Thus, we can say that the predicted value is nowhere close to the actual value

Answer:
a = 54 deg
Step-by-step explanation:
Recall that for a triangle, any exterior angle equals the sum of its two remote interior angles (see attached for reference).
In our case the exterior angle is 2a and the remote interior angles are (a+10) and 44
hence,
2a = (a+10) + 44
2a = a + 10 + 44
2a = a + 54 (subtract a from both sides)
2a - a = 54
a = 54 deg
