Audrey read 280 pages and David read 140 pages in 7 days. Then the correct option is C.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Audrey and David are reading the same book. Audrey reads 40 pages each day. David reads 20 pages each day.
Then the number of pages read after 7 days by Audrey will be given as,
⇒ 40 x 7
⇒ 280
Then the number of pages read after 7 days by David will be given as,
⇒ 20 x 7
⇒ 140
Audrey read 280 pages and David read 140 pages in 7 days. Then the correct option is C.

0.01
0.48 or -1.2
Step-by-step explanation:
Easye as pie
16 ounce is 2.24
24 ounce is 3.12
ok 2.24/16
0.14 price per ounce
for first one
now second one
3.12/24
0.13price per ounce
second one
0.14-0.13=0.01
for last question
2 large boxes=6.24 dollars
each large box=24ounces
2 boxes=48
0.13*48=6.24
6.24 dollars for 2 large boxes
3 small boxes=5.04
0.14 each ounce and 12 each small box
so 12*3=36
36*0.14
5.04
so if the smalle box had 48 ounces it would costs 6.72
2 Large Box=6.24
3 Small box=5.04

The profit y(in dollars) for a business from selling x coats is represented by y=47x . Graph the equation.
The graph of the equation is attached .
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The slope-intercept form of the line equation
y= mx + c
where m is the slope
b is the y-intercept
We are Given that the profit y (in dollars) for a business from selling x coats is represented by the equation
y=47x .
Now comparing with the slope-intercept form of the line equation;
m = 47
We know that the value of the y-intercept can be determined by setting x = 0
substitute x = 0 in the equation
y = 47(0)
y = 0
Thus, the y-intercept b = 1
Thus,
The slope m = 47
The y-intercept b = 1
The graph of the equation is also attached.
(1,47) (2,94) (3,141)
Hence, the line passes through the origin with the y-intercept 0.

Explain how you can find the volume of the figure below. Then, solve- what is the volume of the figure? Make sure to include your units
Answer: a) The figure can be reasonably divided into two geometries:
• a rectangular prism
• a hemisphere.
b) The volume of the rectangular prism is given by
V = lwh
V = (10 cm)(5 cm)(4 cm) = 200 cm³
The volume of the hemisphere is given by
V = (2π/3)r³
V = (2π/3)(3 cm)³ = 18π cm³
c) The total volume of the figure is
total volume = (prism volume) + (hemisphere volume)
V = 200 cm³ + 18π cm³
V ≈ 256.549 cm³

3(x-4)=5(x+2)
Answer:
x = -11
Step-by-step explanation:
1. Distribute 3 to the parenthesis and distribute 5 to the parenthesis
3x-12 = 5x + 10
2. Combine like terms (subtract 3x on both sides and then subtract 10 on both sides)
2x = -22
3. Divide both sides by 2
x = -11
please give me brainliest if this helped
Answer:
x=−11
Step-by-step explanation:
3(x-4)=5(x+2)
Simplify both sides of the equation:
3(x−4)=5(x+2)
(3)(x)+(3)(−4)=(5)(x)+(5)(2)(Distribute)
3x−12=5x+10
Subtract 5x from both sides
−2x−12=10
add 12 to both sides
−2x=22
Divide by -2 both sides
x=−11

Which expression has a value that is equal to the given expression when n = 8? 2n + 10 A. 3n
B. 10n + 2
C. n² + 5
D. 2(n+5)
Answer:
D.
Step-by-step explanation:
2n + 10
When n = 8 we have
2*8 + 10
= 16 + 10
= 26.
When n = 8:
2(n + 5)
= 2(8 + 5)
= 2*13
= 26.
So it's D.
Answer:
D. 2(n+5)

−15x−40=23−8x
What does x =
Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
Add 8x to both sides
-15x + 8x - 40 = 23
-7x - 40 = 23
Add 40 to both sides
- 7x = 23 + 40
-7x = 63
Divide both sides by (-7)
x = 63/-7
x = -9
Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
add 8x to both sides to bring -8x to the left side
-15x + 8x - 40 = 23
add 40 to both sides to bring -40 to the right side
-15x + 8x = 23 + 40
add the common terms
-7x = 63
for x to be alone divide -7 to both sides
x = -9

What value of w makes the equation 145 = w + 27 true?
Answer:
118
Step-by-step explanation:
In the equation 145 = w + 27, you can solve for w by subtracting 27 from 145. That would give you 118. You can check this is correct by adding 27 to 118. 118 plus 27 = 145.
Answer:
118
Step-by-step explanation:
145 = w + 27
Switch the + sign before the 27 and switch into a minus and move it to the other side.
145-27=w
145-27=118
w=118
