Answer:
X = 5
Step-by-step explanation:
28 = 7x + 3 - 2x
28 = 5x + 3
28 - 3 = 5x + 3 - 3
25 = 5x
25/5 = 5x/5
X = 5
Answer:
X = 5
Step-by-step explanation:
1. Combine like terms.
2. Subtract 3 from both sides.
3. Simplify.
4. Divide both sides of the equation by the same term.
5. Simplify.

The right one will be Brainliest and be given 20 points
Answer:
an-1+8 where a1 =10
Step-by-step explanation:
Since 10 is the starting variable we know that a1 is 10.
The Recursive Formula is [tex]a_n[/tex] = 10 + 8n.
What is Recursive Formula?Any term of a series can be defined by its preceding term in a recursive formula (s).
For example: The recursive formula of an arithmetic sequence is, an = an-1 + d. The recursive formula of a geometric sequence is, an = an-1r.
Given:
Opening amount in bank= $10
Each week he will deposit $8.
On End of first week = 10+ 8= $18
On End of second week = 18 + 8= $26
On End of third week = 26+ 8= $34
Continuing this way we get
By end of n weeks, [tex]a_n[/tex] = 10 + 8n

what equation in slope-intercept form represents the line that passes through the points (0,–7) and (–8,3)
Answer:
y=-.5x-7
Step-by-step explanation:
Given m∠8 = 123° and m∠11 = 79°, find the measure of each missing angle.
m∠14 =
m∠9 = 79
m∠4 =
m∠2 =
Picture of question is in the attachment below :
Answer:
m∠1= 157°
m∠2= 23°
m∠3= 157°
m∠4= 23°
m∠5= 157°
m∠6= 23°
m∠7= 157°
Step-by-step explanation:
Given that:
m∠8 = 23°
m∠6= 23 ; m∠8 = m∠6 (vertically opposite angles)
m∠5 = m∠7 ( vertically opposite angles)
m∠5 + m∠6 + m∠7 + m∠8 = 360° (sum of angles at a point)
x + 23 + x + 23 = 360
46 + 2x = 360
2x = 360 - 46
2x = 314
x = 314 / 2
x = 157
Hence,
m∠5 = m∠7 = 157°
m∠1 = m∠5 = 157° corresponding angles
m∠4 = m∠8 = 23° corresponding angles
m∠3 = m∠7 = 157° corresponding angles
m∠6 = m∠2 = 23° corresponding angles

Suppose that it takes a worker aged over 55 an average of 22 weeks to find a new job with a standard deviation of 2 weeks. The distribution is bell shaped. We summarize the distribution as
Answer:
N(22, 2)
Step-by-step explanation:
Suppose that it takes a worker aged over 55 an average of 22 weeks to find a new job with a standard deviation of 2 weeks. The distribution is bell shaped. We summarize the
Mean time of finding a new job : μ = 22
Standard deviation ; σ = 2
Since the distribution give is bell shaped ; this defines a distributon usually described as normal which in standardized form has a mean of 0 and standard deviation of 1.
Hence, the distribution is approximately normal with mean of 22 and standard deviation of 2

In the neighborhood park there is a circular grassy picnic area, but half of the grass has died. The city wants to replant the grass, but needs to know the square footage of the damaged area. If the circular picnic area is 150 feet across, what is the square footage of the damaged area? Let pi = 3.14
Answer:
Thus, πr^2 is the equation for the area of a circle, which is equal to 17662.55 if we quantify it.
Then we have half that to get the dead grass area (square miles), which is 8831.25 square feet, then option B is the solution.

Find the constant of proportionality (r) in the equation y = rr.
Answer:
r = 1
Step-by-step explanation:
We know that x and y are proportional, with the the equation y = rx representing the proportional relationship. Where r = constant of proportionality
Thus the constant of proportionality would be:
r = y/x
Using any of the given pair of values from the table, say (5.8, 5.8),
r = 5.8/5.8
r = 1
What is the equation of the line that passes through the point (−2,1) and has a slope of -5/2
Answer:
You need to make turn this information into slope intercept form: y = mx + b. The m is your slope, the b is your y-intercept. x and y represents the coordinates that the line passes through. Make y = 1, make m = -2, and make x = 2, and you will get: 1 = -2(2) + b. When you simplify, you get 1 = -4 + b, add 4 to both sides and you'll get 5. So my equation is y = -2x + 5. Remember the -2 came from the slope! To get b, substitute the (2,1) in for (x,y) in the equation.

The sum of three consecutive integers is 48. Find the integers.
Answer:
15,16 and 17.
Step-by-step explanation:
Let the three consecutive integers are x, x+1,x+2
ATQ,
x+x+1+x+2=48
3x+3=48
Subtract 3 from both sides,
3x+3-3=48-3
3x=45
x = 15
First integer = 15
Second integer = 15+1 = 16
Third interger = 15+2 = 17
Hence, three integers are 15,16 and 17.

Every week Jim runs 8 miles and bikes 12 miles.Write an ordered pair to represent how many miles Jim runs a bikes in 5 weeks.Use the drop-down menus to complete the sentence!
Answer:
The ordered pair ( 8,12) can be written as (40,60) for values of r (=x) and
b (=y) for 5 weeks.
Step-by-step explanation:
Every week Jim runs 8 miles and bikes 12 miles.
Let the week be represented by w , running miles by r and biking miles by b
therefore
1w= 8r + 12 b
Multiplying both sides by 5
5(1w= 8r + 12 b)
5(1w) = 5(8r + 12 b )
5w= 40r + 60b
Jim runs 40 miles and bikes 60 miles in 5 weeks
The ordered pair ( 8,12) can be written as (40,60) for values of r (=x) and
b (=y) for 5 weeks.
The answer is written in the form (x, y) where x is written before y in the ordered pair. We treat running miles as x and biking miles as y.
A drawing has been enlarged using a scale of 1inch = 1.5 inches.if the original drawing was 4.6inches long , how long is the is the enlargement?
Answer:
6.9 inches
Step-by-step explanation:
From the above question:
Scale =
1 inch = 1.5 inches
Original drawing = 4.6 inches
Hence:
1 inch = 1.5 inches
4.6 inches = x
Cross Multiply
x = 4.6 × 1.5 inches
x = 6.9 inches.
Therefore, the length of the enlargement = 6.9 inches
