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?
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

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 28.8PLEASE I NEED HELP!! what are two ways that you can tell that two ratios form a proportion? i really need to pass this test to get my grades up, I'm not trying to cry my whole winter break.
Answer:
A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "twenty is to twenty-five as four is to five."
Step-by-step explanation:
Answer:
A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fraction in it’s simplest form. Another way is to see if the numbers in the ratios are factors or multiples of each other. For example, 10:5 and 30:15. 10:15= 10/5 and 30:15= 30/15. Then you put it in simple form. 10/5 = 2 and
30/15 = 2. Therefore 10:5 and 30:15 are proportional.

Which of these relations is a function?
I’m I correct??
Answer:
the first one on the bottom
Step-by-step explanation:
There is a little trick to find out if it is a function or not. This trick is called the vertical line test. if you can scan the figure with a virtual line and it does not touch more than one side of the figure at one time then it is a function. if it touches more than one side or line of the figure it is not a function.

8v - 4(v + 8) = 8
O v = 2
O v = 10
ng
v=4
o
v=-4
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

using the equation y=-6x+1: if you choose -2 as the input ,what will be the output
Answer: 13
Step-by-step explanation: you substitute x for -2 because the input is known as x. The output is known as y; solving the new equation y=-6(-2)+1 you will get y=12+1 then y=13

equivalent answers for 64 to the power of 2/3
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.

Find the slope?
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

Which table has a constant of proportionality between yyy and xxx of 0.30.30, point, 3?
Answer:
Answer
Step-by-step explanation:
The answer is C
You would do 1.2 ÷ 4 which is 0.3
2.4 ÷ 8 is 0.3
3.9 ÷ 18 is 0.3
A is wrong because the constant of proportionality is 0.33333
B is wrong because the constant of proportionality is 0.6

Step-by-step explanation:
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.
Answer:
yes he is correct
Step-by-step explanation:
if he is painting 1/5 of a room in 1/5 of a day he is painting 1 room in 1 day therefore he can paint 6 rooms in 6 days
Write the following in standard form.
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]
Hope this helped!
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?
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.
