Step-by-step explanation:
a+2= b
5a - 8 =2b
a= b- 2
since(a= b- 2)
5(b-2) -8 = 2b
5b -10 - 8 = 2b
3b -18 =0
3b=18;b=6
since b =6
a= 6-2 ; a= 4

the angle measures of a triangle are in the ratio 5:6:7. find the angle measures of the triangle
Answer:
50°, 60°, 70°
Step-by-step explanation:
Sum the parts of the ratio, 5 + 6 + 7 = 18 parts
The 3 angles in a triangle sum to 180° , then
180° ÷ 18 = 10° ← value of 1 part of the ratio, then
5 parts = 5 × 10° = 50°
6 parts = 6 × 10° = 60°
7 parts = 7 × 10° = 70°
The angle measures of the triangle are 50° , 60° , 70°

~ N(,)
What is the probability that the average of 35 numbers will be less than 7.9?
Answer:
22.5
Step-by-step explanation:
The required Distribution, selection and probability is X to U(4,11), x to N (7.5, 0.3415) and 0.87932 respectively.
(a) Distribution of X is uniform distribution X to U(4,11).
(b) Sample size (n) = 35, distribution of mean would be moderate with value = (4+11)/2 = 7.5
Standard deviation = √ [(11-4)^2/(12*35] = 0.3415
Now
x to N (7.5, 0.3415)
(c) We have to find probability that the average of 35 numbers will be less than 7.9.
P(x < 7.9) = P(x < 7.9; 7.5; 0.3415)
Z = (7.9 -7.5)/0.3415
Z = 1.1713
P(x< 7.9)= P(Z < 1.1713)= 0.87932.
Thus, The required Distribution, selection and probability is X to U(4,11), x to N (7.5, 0.3415) and 0.87932 respectively.

Answer:
the answer is 22 percent which is science
Answer:
100 marks have been obtained in the hindi subject.
Step-by-step explanation:
First you have to find how many marks are obtained by one degree. So you have:
450marks/360°=1.25marks/degree
Then you have to find how many marks are obtained for each subject.
1.25marks/degree×80°= 100 marks
1.25×72= 90 marks
1.25×70= 87.5 marks
1.25×90= 112.5 marks
1.25×48= 60 marks
100+90+87.5+112.5+60=450 marks

7. Write the equation of a line which passes through the points (-3,5) and (6,23)
Answer:
answer to the equation is
[tex]y = 2x + 11[/tex]
Step-by-step explanation:
[tex]y = mx + b[/tex]
first find the slope of the line using the two points
[tex]slope \: m = \frac{y2 - y1}{x2 - x1} = \frac{23 - 5}{6 - ( - 3)} \\ = \frac{18}{9} \\ slope \: m = 2[/tex]
substitute 2 for m and use one of the points for x and y and solve for b
[tex]5 = 2( - 3) + b \\ 5 = - 6 + b \\ 5 + 6 = b \\ b = 11[/tex]
Now that you found b, the y-intercept, you can substitute that into the equation for your line
[tex]y = 2x + 11[/tex]

If you look carefully, you will see that all pairs are congruent.
They have all corresponding sides equal and all corresponding angles equal too.
They would overlap after rotation, translation or combination of both.
Correct choice is E

In the diagram below, AB and CB each have a length of 5 centimeters. If m<A=6(x-3) and m<C=4(x+1), determine the value of each angle of the triangle.
Considering that angles A and C are equal, and the sum of the internal angles of a triangle is 180º, we have that:
The measure of angle A is of: 48º.
The measure of angle B is of: 84º.
The measure of angle C is of: 48º.
-----------------------------
Segments AC and CB have the same length, thus, angles A and C have the same measure, and then:[tex]6(x - 3) = 4(x + 1)[/tex]
[tex]6x - 18 = 4x + 4[/tex]
[tex]2x = 22[/tex]
[tex]x = \frac{22}{2}[/tex]
[tex]x = 11[/tex]
[tex]6(11 - 3) = 6(8) = 48[/tex]
The measure of angle A is of: 48º.
The measure of angle C is of: 48º.
The sum of the internal angles of a triangle is of 180º, and this is used to find the measure of angle B.
[tex]mA + mB + mC = 180[/tex]
[tex]2(48) + mB = 180[/tex]
[tex]mB = 84[/tex]
The measure of angle B is of: 84º.

six less than twice a number x is 38 whats the value ofx
Answer:
x=22
Step-by-step explanation:
We would do the opposite so "six less" we would add 6 to 38. 6+38= 44 and "twice a number" we would divide by 2. 44 /2= 22. So the answer would be 22.
Hope this helps! :)
Answer:
Answer is 22
Step-by-step explanation:
38+6=44
44 ÷ 2= 22

Solve the equation: 3/8g + 2 = 5
Answer:
3/8g + 2 = 5
Subtract the number 2 from both sides of the equation.
3/8g = 3
Now divide 3/8 from both sides of the equation.
3/8 divided by 3/8 equals 0. 3 divided by 3/8 equals 8.
The final answer is:
g = 8
------------------------------------------------------------------------------------------
Check your answer:
3/8g + 2 = 5
Substitute 8 into the spot where the variable g was.
3/8 X 8 + 2 = 5
So our answer x = 8 is true.

The field trip will cost $7 per student plus a one time fee of $55 for a bus to rent.
Write an expression to find the total cost of the field trip for (s) students.
Answer:
$55*($7s)
Step-by-step explanation:
So there is a one time fee for the bus. Its $55. You only pay for it once. However each student has to pay $7 to get on the bus. So 7 times how ever many students there are plus 55 dollars for the bus rent fee.
