What is the solution to the equation?

O v = 2
O v = 10
ng
v=4
o
v=-4
Answers
Answer:
v =10
Step-by-step explanation:
8v - 4(v + 8) = 8
Distribute
8v -4v -32 = 8
Combine like terms
4v -32 = 8
Add 32 to each side
4v -32+32 =8+32
4v = 40
Divide by 4
4v/4 = 40/4
v =10
Answer:
v = 10
Step-by-step explanation:
Expand 8v - 4(v + 8) = 8 and then combine like terms:
8v - 4v - 32 = 8, or
4v = 40
Then v = 40/4, or v = 10
Holly has $225 to spend at the shopping mall. She decides to buy sweaaters and pants with her money. Sweaters cost $45 each and pants cost $25 each. The equation 45s + 25p = 225 represents this situation.
If Holly buys 3 sweaters, what is the greatest number of pants she can buy?
Answers
Answer:
3 pairs of pants
Step-by-step explanation:
Plug 3 in for s. Your equation should now be 45(3) +25p=225
Then distribute 135+25p=225
Subtract 25p=90
Divide p=3.6
Since you cannot buy half of a pair of pants you need to round down to three

A painter painted about a fifth of a room in a fifth of a day. Coley estimated the painter would paint 6 rooms in 6 days. Is Coley's estimate reasonable? Complete the explanation.
EXPLANATION: Coley's estimate (is not/is) reasonable because the painter's unit rate is (blank) room per day, so in 6 days the painter would paint about (blank) rooms.

equivalent answers for 64 to the power of 2/3
Answers
Answer:
16
Step-by-step explanation:
Dealing with a fraction exponent on hand can be converted by using the fractional exponents rule where the fraction exponent is converted to something like this:
[tex]64^\frac{2}{3} = \sqrt[3]{64^{2}}\\[/tex]
As you can see, the denominator of the fractional exponent is now the index of the radical. Here is a guide to know what goes where.
[tex]64^\frac{x}{y} = \sqrt[y]{64^{x}}[/tex]
Both the original problem (64^2/3) and the converted formula can be put into a calculator.
Simplify (if you want to)
[tex]\sqrt[3]{64^{2}}\\\sqrt[3]{4096}\\16[/tex]
64 to the power of 2/3 is 16.

Write the following in standard form.
Answers
Answer:
[tex]\huge\boxed{3x+y=23}[/tex]
Step-by-step explanation:
First off, let's note that when given a slope and a point, we will write our equation in the form [tex]ax+by=c[/tex], where a is the slope and c is the y-intercept.
Since we know the slope, but not the y-intercept, we can start to fill in what we already know.
[tex]3x+y=c[/tex]
Therefore to finish this equation, we must find the y-intercept.
Since we know that the point (7, 2) runs through this line, we can plug it into our formula ([tex]3x+y=c[/tex]) to find the y-intercept, b.
2 is the y, 7 is the x, -3 is the slope, so we can plug it into the equation to find b.
[tex]3(7) + 2 = c[/tex] [tex]21+2=c[/tex] [tex]23 = c[/tex]This means that the y-intercept for our graph is 23. Now that we know this, we can plug it into our equation ([tex]3x+y=c[/tex]) as b and finish up the equation for the line.
[tex]3x+y=23[/tex]

Answer:
The rate is 15 minutes per meter.
Step-by-step explanation:
It takes 9 minutes to fill a depth of meters.
Filling meters take 9 minutes time.
Filling 3 meters of the aquarium takes = 45 minutes time (Multiplying by 5 both the numbers).
In order to fill 1 meter of the aquarium it will take minutes (Dividing by 3 both the numerical values).
===================================================
Work Shown:
8 minutes = (2/5) meters
5*(8 minutes) = 5*( (2/5) meters )
40 minutes = 2 meters
40/2 minutes = 2/2 meters
20 minutes = 1 meter
The unit rate in minutes per meter is 20 minutes per meter.
In other words, it takes 20 minutes to raise the level 1 meter.

There is a little trick to find out if it is a function or not.

Prove step by step that 5^20-5^19 is an even number with out using a calculator Please can you tell me the steps and why?
Answers
9514 1404 393
Answer:
factor out 5^19
Step-by-step explanation:
a) Reason from parity:
both 5^20 and 5^19 are products with only odd numbers (5) as factors. Hence each is an odd number. The difference of odd numbers is always even.
__
b) Factor:
5^20 -5^19 = 5^19(5 -1) = 5^19×4
This product has an even factor (4), so is even.

The bicycle with a 30-inches diameter rolls approximately 28.8 more than a tire with the diameter with 21-inches.
How to solve:
First use the formula: C = 3.14dReplace the d value with 30 and solve the equation:C = 3.14 x 30 ⇒ 94.2477796077
Then solve the equation again but 21 as the d value:C = 3.14 x 21 ⇒ 65.9734457254
Then subtract 65.9734457254 from 94.2477796077 to get the approx. answer of 28.8Which table has a constant of proportionality between yyy and xxx of 0.30.30, point, 3?

Find the slope?
Answers
Answer:
1/4
Step-by-step explanation:
the equation for slope is (y2 - y1) / (x2 - x1)
so the equation is (4-8)/(3-19)
= -4/-16
= 4/16
= 1/4, therefore, the slope is 1/4 or 0.25 as a decimal
