Answer:
5*(x+8)-(7*x+38)=0
5 • (x + 8) - (7x + 38) = 0
2 - 2x = -2 • (x - 1)
-2 • (x - 1) = 0
-2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
x-1 = 0
x = 1
Lin has a pet German shepherd that weighs 38 when measured in one unit and 84 when measured in a different unit. which measurement is in pounds, and which is in kilograms?
Given :
Lin has a pet German shepherd that weighs 38 when measured in one unit and 84 when measured in a different unit.
To Find :
Which measurement is in pounds, and which is in kilograms.
Solution :
We know, mass in kg and pounds are related as :
[tex]m_P = 2.2m_{kg}[/tex]
Putting, [tex]m_{kg}=38[/tex] and [tex]m_P=84[/tex] , we get :
LHS = 84
RHS = 2.2 × 38 = 83.6 ≈ 84
Since, LHS = RHS .
Therefore, 38 units is Kg and 84 units in Pounds.
Hence, this is the required solution.

Answer:
y-intercept is 1500 and represents the fixed cost.
slope is 100 and represents the number of wristbands sold.
Step-by-step explanation:
Slope is rise over run.
100 up, 1 over.
y-intercept is where the line meets the y-axis, this case 1500. 1500 represents the payment Appleseed spent without selling any wristbands.
The park district is starting a new softball league. The table shows
how many coaches will be needed, depending on how many
players sign up.
Players 20 35 50
Coaches 4 7 10
Using the proportional relationship in the table, how many
coaches will be needed for 80 players?
A8
16
21
40
Answer:
16
Step-by-step explanation:
Since there is always a certain amount of coaches per # of players we have to find that. If there are 20 players and 4 coaches that means 5 players per coach. if there are 35 players and 7 coaches that means again 5 players per coach. Therfore we know that 5 players per coach is constant. If we have 80 players we set up a proportion to solve. 80players / x coaches = 5 players per/ 1 coach. Cross multiply and solve. 80=5x

What is meant by expression?In mathematics, an expression is a sentence that contains at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression, also known as an algebraic expression, is a mathematical statement made up of numbers, variables, and an arithmetic operation between them. For example, 4m + 5 is an expression in which the terms 4m and 5 are separated by the arithmetic sign + and m is the variable of the given expression.Given,
5 (4 + 3) - 3 (3 + 2)
Follow the PEMDAS order of operations

The regular price of a swimsuit in the junior department of a store is $54. The store advertises an end-of-season sale at 40% off the regular price of all swimsuits. Two weeks later the store advertises a bonus sale at an additional 1/5 off the end-of-season sale price of all swimsuits. Shannon and Mary decide this is a great time to shop for swimsuits. Shannon figures that the swimsuits are now 60% off the regular price. Mary disagrees, because she figures that the total discount is actually less than 60%.
a. What is the cost of a swimsuit during the end-of-season sale? Justify your reasoning using a model.
b. What is the cost of a swimsuit during the additional 1/5-off bonus sale? How can you show this with a model?
c. Did Shannon or Mary figure the discount correctly? Use a model to explain.

Martha wants to go to band camp this summer that costs $103.50 she has $10 and plans to save $5.50 each week. How many weeks will it take her to save the money? In algebra pls
Answer:
19 weeks
Step-by-step explanation:
You'll be looking for an equation the form of
y=mx+b
Given:
b = $103.50
m = $5.50
x = ? (where x is in weeks)
Next, set y = 0
--> mx+b = 0
Rearrange
x = (-b/m)
Plug in b and m:
x = (-(-103.5)/5.5) = 18.818
Rounding up, it will Martha 19 weeks to save enough money.

Answer:

Step-by-step explanation:
The exterior angles of the polygon are the supplement of the interior angles, so are ...
180° -174° = 6° . . . . measure of each exterior angle
The sum of exterior angles is 360°, so ...
n(6°) = 360°
n = 360°/6° = 60
The polygon has 60 sides.
Answer:
The polygon has 60 sides.
Step-by-step explanation:
Each interior angle = 174°
Each exterior angle = 180° - 174° = 6°
Sum of all exterior angles = 360°
6x = 360° (x = no. of exterior angles)
x = 360°/6
x = 60
If it has 60 exterior angles it has 60 interior angles.
