Answer:
an=3+12n
Step-by-step explanation:
The sequence is
15, 27, 39, 51
The first term: a 1 = 15
The common difference of this sequence : d = 27 − 15 = 12
The nth term of an arithmetic sequence is given by formula
an=a+(n−1)d
So a n for this sequence will be:
an = 15 +(n−1) 12
an =(15)+12n−12
an = 3+12n
The measures of the angles of a triangle are shown in the figure below. Solve for x.
(6x+3)°
27°
Answer:
x = 10
Step-by-step explanation:
1. The sum of all angle measures in any triangle is equal to 180 degrees.
This means that 90 + 6x + 3 + 27 = 1802. (Solving)
Step 1: Combine like terms.
[tex](6x)+(90+3+27)=180[/tex] [tex]6x + 120 = 180[/tex]Step 2: Subtract 120 from both sides.
[tex]6x + 120 - 120 = 180 - 120[/tex] [tex]6x = 60[/tex]Step 3: Divide both sides by 6.
[tex]\frac{6x}{6}=\frac{60}{6}[/tex] [tex]x = 10[/tex]Therefore, x = 10.

g = f - d / v what is f
Answer:
f = g + d/v
Step-by-step explanation:
g = f - d/v
add d/v to both sides
g + d/v = f
switch sides
f = g + d/v
Please help me with this question
Answer:
x = 2
Step-by-step explanation:
Any lower base angle is supplementary to any upper base angle, then
51x + 3 + 75 = 180
51x + 78 = 180 ( subtract 78 from both sides )
51x = 102 ( divide both sides by 51 )
x = 2

Answer:
smaller t= 0
larger t= 4
Step-by-step explanation:
smaller t is the t sqrd
larger t is the 4t
h(t) = t^2 + 4t + 3
h(0) = (0)^2 + 4(0) +3
0 + 0 + 3

The ratio of boys to girls in the sixth grade is 3:5. If there are 20 more girls than boys, how many total students are in the sixth grade?
Answer:
80
Step-by-step explanation:
.375, .525, .25 difference. 20/.25 =80
There are 80 students in the sixth grade.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
Thus, a = px, b = qx
We have been given that ratio of boys to girls in the sixth grade is 3:5. If there are 20 more girls than boys, then
Now we need to do as;
b = 20 + g
3x = 20 + 5x
x = 10
Now The students are 8p
8 x 10 = 80
Hence, there are 80 student.

Find the slope and y-intercept from the graph. Then enter the equation for the graph in slope-intercept form.
The table numbers are (0,9) (1,13) (2,17) (3,21) (4,25)
Answer: y=4x+9
Slope = 4
Step-by-step explanation:
y2-y1/x2-x1
Given 3,21 and 4,25
25-21/4-3 = 4/1 = 4
Slope = 4
You can use the point-slope formula to get the following equation in slope-intercept formula.
y-y1 = m(x-x1)
(4,25)
->
y-25=4(x-4)
Distribute
y-25=4x-16

Name the common vertex of all the angles.
The measures of the angles of a triangle are shown in the figure below. Find the measure of the smallest angle
Answer:
x=7, so the smallest angle would be 44?
Step-by-step explanation:
Okay, so in a triangle, all the angles have to add up to 180°. So your equation would be 44 + (5x+20) + (9x+18) = 180
So in order to find the smallest angle, you have to find x, so let's simplify the equation.
Add the like terms (5x + 9x = 14x) and then the regular integers (44 + 20 + 18 = 82)
So now we have 14x + 82 = 180. Subtract 82 from both sides of the equation, and you will have 14x = 98.
Divide both sides by 14, and you will get x = 7.
Now plug this in to both equations, and see which one is the smallest.
9(7) + 18 = 63 + 18 = 81
5(7) + 20 = 35 + 20 = 55
I'm not sure whether or not your problem meant "find the smallest angle with a variable" or just the smallest angle in general, but I hope this helps.

Which of the following is the graph of 2x - 3y = 6?
Answer:
Option B (second graph)
Step-by-step explanation:
Given the linear equation in standard form, 2x - 3y = 6:
It's easier to figure out the corresponding graph by transforming the equation into its slope-intercept form, y = mx + b:
2x - 3y = 6
2x - 2x - 3y = 6 - 2x
-3y = -2x + 6
Divide both sides by -3:
[tex]\frac{-3y}{-3} = \frac{-2x+6}{-3}[/tex]
y = 2/3x - 2
Now that we have the slope-intercept form, it's easier to tell that Graph B represents the given equation because:
The graph's y-intercept occurs at (0, -2).The slope, m = 2/3, is positive. If you use the "Rise over run" technique, you'll see that Graph B rises by 2 units, and runs by 3 units.Therefore, the correct answer is Graph B.
