Answer:
Step-by-step explanation:
Simplifying :8x + -20 = 3x + 5
Reorder the terms:-20 + 8x = 3x + 5
Solving:-20 + 8x = 5 + 3x
Add '-3x' to each side of the equation:-20 + 8x + -3x = 5 + 3x + -3x
Combine like terms: 8x + -3x = 5x :-20 + 5x = 5 + 3x + -3x
Add '20' to each side of the equation:-20 + 20 + 5x = 5 + 20
Combine like terms: -20 + 20 = 0 :0 + 5x = 5 + 20
5x = 5 + 20
Divide each side by '5':x = 5
Simplify:x=5

8 $42,000
9 $48,000
10 $54,000
Answer:
The answer is "p= $5,246".
Step-by-step explanation:
Using formula:
Present value of [tex]\frac{in-flow}{out-flow}[/tex] = cash-flow [tex]\times[/tex] present value of discounting factor(rate %, time period)
[tex]\to -p-\frac{2p}{1.08}-\frac{4p}{1.08^2}- \frac{8p}{1.08^3}-\frac{16p}{1.08^4} =\frac{24000}{1.08^5}+ \frac{30000}{1.08^6}+ \frac{36000}{1.08^7} + \frac{42000}{1.08^8}+ \frac{48000}{1.08^9}+ \frac{24000}{1.08^{10}}\\\\[/tex]
[tex]\to -p[1+\frac{2}{1.08}+\frac{4}{1.08^2}+ \frac{8}{1.08^3}+\frac{16}{1.08^4}] = 127960.43169\\\\\to -p[24.3923427] = 127960.43169\\\\\to -p = \frac{127960.43169}{24.3923427}\\\\\to p= 5245.93\\\\\to p= 5246[/tex]

Emilie rides her bike x miles before she gets a flat tire. She walks 1/3 mile to a bus stop and then takes a bus for 2 1/2 miles. Which expression shows how many miles Emilie travels in all?
Answer there is no choice, but it is x+1/3+2 1/2.
Step-by-step explanation:
Answer:
The answer is x + 2 5/6.
Step-by-step explanation:
Emilie rides her bike x miles before it gets a flat tire.
She walks 1/3 mile to a bus stop and then goes another 2 1/2 miles or 5/2 miles on a bus.
The equation would be:
x + 1/3 + 2 1/2
But, since that isn't an option, we have to simplify the equation.
x + 1/3 + 5/2
= x + [tex]\frac{2+15}{6}[/tex]
= x + 17/6
= x + 2 5/6
Thus, the answer is x + 2 5/6.

$685.25
$748.72
$721.19
Answer:
The correct answer is 748.72
Step-by-step explanation:
$748.72 is applied to the principal balance if you pay $1,678.93 at the end of the first month.
What is principal amount?The loan amount that the lender gave to the borrower is referred to as the primary amount. Also, it is the factor the lender uses to calculate interest.
Please be aware that the amount you pay toward your loan's principal is without the interest that is charged on that amount. Your lender determines how much interest customers will pay over a specific length of time based on the amount still owing. The principle amount is simply the amount you owe their lender before interest.
principal amount = 4.75% of $1,678.93
= 4.75% × $1,678.93
= $748.72
Therefore, $748.72 is applied to the principal balance if you pay $1,678.93 at the end of the first month.

which represents an even function?
y=cos(x)
I think the one that represents a even function is cos(x)
Answer:
The cosine is an even function which means that if (x,y) is on the graph of the function so too is the point (-x,y). Since y corresponds to cos(x) then this means that cos(-x) = cos(x).

Candice scored 74 on an exam that had a mean of 66 and a standard deviation of 4. Erin scored 58 on an exam with a mean of 42 and a standard deviation of 7. Who scored better?
Answer:
Erin
Step-by-step explanation:
Z score formula:
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
For Candice:
Z score = 74 -66/4
Z score = 2
For Erin
Z score = 58 - 42/7
Z score = 2.28571
Erin z score is larger hence, he did better

A.25·4·3/5
B.5/3·25·1/4
C.3\5·25·1\4
D.3/5·1/25·1/4
Answer:
C
Step-by-step explanation:
The expression that uses the commutative property is 3/5 × 25 × 1/4
What is the commutative property?The commutative property is a math rule that says that the order in which we multiply numbers does not change the product.
Given is an expression 3/5 × 1/4 × 25
We know that,
The commutative property of multiplication states that:
A × B × C = B × C × A
Using the above equation, we have the result of the commutative property to be:
3/5 × 1/4 × 25 = 3/5 × 25 × 1/4
Hence, the expression that uses the commutative property is 3/5 × 25 × 1/4

A circular fountain has 132 feet of railing around it. What is the area of the fountain to the nearest square foot? Use 3.14 for π. *
Answer:
139
Step-by-step explanation:
First we need to find diameter 132/3.14=42 rounded
Then we halve it to find radius 42/2=21
Formula for area is radius x radius x 3.14
21 x 21 = 441 x 3.14 = 138.74 round up is 139
Answer:
18.8 feet, 59.1 feet to the nearest tenth
Step-by-step explanation:
The diameter is the line drawn that divides the circle into two while the circumference is the perimeter of the circle. Both are a measure of the radius of the circle.
The diameter D = 2r where r is the radius of the circle
The circumference = 2Πr = ΠD where Π = 22/7
Given that the circular fountain has a radius of 9.4 feet
Its diameter = 2 × 9.4 feet = 18.8 feet
The circumference = 22/7 × 18.8 feet
=59.09 feet
≈ 59.1 feet to the nearest tenth
A submarine is -18 feet below the surface of the ocean. The submarine then dove to a depth of -50 feet below the surface of the ocean. What was the change in depth?
Answer:
-32ft
Step-by-step explanation:
Given parameters:
Original depth of the submarine = -18ft
New depth = -50ft
Unknown:
Change in depth = ?
Solution:
The change in depth will be the difference in depth between the new and original depth.
Change in depth = New depth - original depth
Change in depth = -50ft - (-18ft) = -32ft
The change in depth of the submarine is -32ft.
