Answer:
20p = x
Step-by-step explanation:
Since Lily sold 5 purses in week one and 15 purses in week two that adds up to be a total of 20 purses sold in two weeks. Since p represents the profit for each purse she can use the expression below which simply multiplies the profit per purse (p) by the total amount of purses sold in the two weeks which would give her the total amount of profit (x) that she made from all of her sales.
20p = x

x = a
Answer:
x=3
Let me know if you need an explanation.
Answer:
x = 3
Step-by-step explanation:
Step 1. add 11 to both sides
3x + 4 = 8x - 11
+11 +11
3x + 15 = 8x
Step 2. subtract 3x from both sides
3x + 15 = 8x
- 3x -3x
15 = 5x
Step 3. divide by 5 to isolate x
15 = 5x
/5 /5
x = 5
5 divided by 15.90

128 lb of dog food for 16 dogs
4. A store offers packing and mailing services to
customers. If a customer ships a box
weighing 4 pounds, it would cost $15. If a
customer ships a box weighing 8 pounds, it
would cost $23. Identify the following
characteristics:
Answer/Step-by-step explanation:
In the situation explained in the question, the cost of shipping is dependent on the weight of the box to be shipped.
For a box of 4 pounds, total shopping cost (x) => $15 (y)
For a box of 8 pounds (x), total shopping cost => $23 (y)
Therefore:
a. The input is weight of box
b. The output is cost of shipping
c. Using the 2 given pair (4, 15) and (8, 23), slope is calculate using the formula below:
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{23 - 15}{8 - 4} = \frac{8}{4} = 2 [/tex]
Slope = 2
d. The slope represents the amount charged per pound of weight. That is, $2 per pound.
e. Let's derive an equation to represent the situation using the slope-intercept formula given as y = mx + b
y = total cost of shipping
x = weight of box
m = average cost per pound = slope
b = y-intercept = flat fee charged for shipping before adding the cost of weight per pound
Substitute x = 4, y = 15, m = 2 into y = mx + b, and solve for b
15 = 2(4) + b
15 = 8 + b
15 - 8 = b
7 = b
b = 7
The equation would be y = 2x + 7
The y-intercept = 7
f. The y-intercept, 7, is the starting amount, that is the flat fee charged before the cost per pound of weight of a box is added to give total cost of shipping.

Step-by-step explanation:
A hill on a hiking trail goes up to 69 feet over a distance of 138feet. Find the grade of the hill
Answer: The grade of the hill = 50%
Step-by-step explanation:
The grade is the slope( expressed as a percent). To evaluate the slope we divide the rise by the run.
Given: A hill on a hiking trail goes up to 69 feet over a distance of 138 feet.
So, rise= 69 feet , run = 138 feet.
The grade of the hill = [tex]\dfrac{rise}{run}\times100[/tex]
[tex]=\dfrac{69}{138}\times100=50\%[/tex]
Hence, the grade of the hill = 50%

Triangle H J K is shown. Lines are drawn from each point to the opposite side and intersect at point G to form line segments H C, J E, and K D.
In the diagram, JG = 5 cm and GE = 10 cm. Based on this information, can G be a centroid of triangle HJK?
Point G cannot be a centroid because JG does not equal GE.
Point G cannot be a centroid because JG and GE are in the ratio 1:2.
Point G can be a centroid because GE and JG are in the ratio 2:1.
Point G can be a centroid because JG + GE = JE.
Answer:its B for anyone doing edge

What is f(5) for the function f(x)=-9x-10
Step-by-step explanation:
In this form, x = 5.
so we'll substitute 5 in for x...
f(5) = -9(5) -10
f(5) = -45 -10
f(5) = -55
essentially saying, when x = 5, y = -55
A square patio has an area of 147 square feet. How long is each side of the patio to the nearest tenth?
Answer:
37. Because 147 divided by 4 (square has 4 sides lol) and you come up with 36.75 and then you gotta round it to the nearest tenth which makes it 37.

A savings account earns 2.7% yearly interest. Which equation shows how many years, t, it will take for the account to double?
Answer:
1.027t = 2
Step-by-step explanation:
Given that :
Saving account earns 2.7% interest yearly
The number it will take for the account to double
Let
Number of years = t
Interest earned yearly = 2.7% = 0.027
Amount = p(1 + rt)
Where P = principal
R = rate ; t = time in years, A = final amount
If p = 1 ;
For account to double,
Final amount = 2 * principal (p)
final amount = 2 * 1 = 2 ; hence, Final amount = 2
2 = 1(1 + 0.027t)
2 = 1 + 0.027t
2 = 1.027t

Answer:
9. y= ¼x -5
10. y= 2x +18
Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the slope (also known as gradient) and c is the y-intercept.
9. The given equation is already written in the slope-intercept form. The coefficient of x is ¼, thus the gradient of the given line is ¼.
Parallel lines have the same gradient and hence, gradient of line is also ¼.
Substitute m= ¼ into the equation:
y= ¼x +c
To find the value of c, substitute a pair of coordinates.
When x= 8, y= -3,
-3= ¼(8) +c
-3= 2 +c
c= -3 -2
c= -5
Thus, the equation of the line is y= ¼x -5.
10. Gradient of given line= 2
Parallel lines have the same gradient.
Thus, gradient of line= 2
Substitute m=2 into the equation:
y= 2x +c
When x= -4, y= 10,
10= 2(-4) +c
10= -8 +c
c= 10 +8 (+8 on both sides)
c= 18
Therefore, the equation of the line is y= 2x +18.
Nora jogs 414 miles on Monday. She jogs 112 fewer miles on Tuesday. Write and evaluate an addition expression to find how many miles Nora jogs on Tuesday.
Answer:
Let's define the variables:
M = # of miles that Nora jogs on Monday
T = # of miles that Nora Jogs on Tuesday
We know that:
"Nora jogs 414 miles on Monday"
Then we have:
M = 414 mi
"She jogs 112 fewer miles on Tuesday"
This can be written as:
T = M - 112 mi
This is the equation that we need to solve.
Here we can simply replace the value of M by 414mi and get:
T = 414 mi - 112 mi = 302 mi.
Nora jogs 302 miles on Tuesday.

Will anyone help me on this? what do i shade green and red?? please let me know! everyone who's answered on this app has given weird, random responses. thanks in advance!
Step-by-step explanation:
Hοmοzygous means both letters are uppercase, or both are lowercase.
Heterozygous means one is uppercase and the other is lower case.
Dominant is represented by uppercase. Recessive is represented by lowercase.
"Hοmοzygous dominant" is NN.
"Heterozygous" is Nn.
"Hοmοzygous recessive" is nn.
Shade NN red, and shade Nn green. Leave nn unshaded.
