Your friend states that he has quarters and dimes in his pocket that total to $5.00. He
also states that there are 6 more quarters than dimes. If there are 26 coins altogether,
how many quarters and dimes are there?
Need help!!
Answer: There are 16 quarters and 10 dimes.
Step-by-step explanation:
Let x = Number of quarters
y= Number of dimes.
As per given,
x+y = 26 (i)
x= y+6 (ii), substitute this in (i), we get
y+6+y= 26
⇒2y+6=26
⇒ 2y = 26-6=20
⇒ 2y =20
⇒ y =10 [Divide both sides by 2]
Put this in (ii), x= 10+6 =16
So there are 16 quarters and 10 dimes such that 16 (0.25)+10(0.10)= $5 .

Equation: y = 2x + 4
72 = 2x + 4
68 = 2x
x = 34
Hope this helps! :)
Slope of the line: rise/run = 4/2 = 2
y-intercept = 4
Plug into y = mx+b
y = 2x + 4
Plug 72 for y

The function c(x) = 2.5x + 15 shows the cost, in dollars, to make x necklaces.
What is c(10)?
What is c(15)?
What is the best interpretation of c(20) = 65 in terms of the problem?
Answer:
c(10)=40
c(15)=52.5
Step-by-step explanation:
c(10) means you plug 10 into your x same with (c15) you plug in 15 so for c(10) it would be 2.5(10) + 15 which is 40
The value of c(10) and c(15) is 40 and 65 respectively.
The given function is c(x) = 2.5x + 15.
What is the function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Now, c(10)=2.5(10)+15=40
c(15)=2.5(15)+15=52.5
Given c(20) = 65
So, 65=2.5x+15
⇒50=2.5x
⇒x=20
Therefore, the value of c(10) and c(15) is 40 and 65 respectively.

The function f(x)=0.39x+10.9 can be used to predict diamond production. For this function, x is the number of years after 2000, and f(x) is the value (in billions of dollars) of the year's diamond production. Use this function to predict diamond production in 2006 The diamond production in 2006 is predicted to be $[ ] nothing billion.
Answer:
The diamond production is 2006 is expected to be 13.24 billion
Step-by-step explanation:
Here, we want to predict the diamond production is 2006
The equation to use is given in the question as;
f(x) = 0.39x + 10.9
Since x is the number of years after 2006, in this particular question, x will be 2006-2000 = 6
So f(6) = 0.39(6) + 10.9
f(6) = 2.34 + 10.9
f(6) = 13.24 billion
PLEASE HELP!50 POINTS! Brainiest if you know how to do it. I will report you if you're just guessing or very wrong. How do I find the least common denominator in these?
Which of the following is the least common denominator for w-5/w-7 and w+8/3w?
A. 3w (w − 7)
B. w (w − 7)
C. 3w − 7
D. 3(w + 7)
Answer:
A) 3w(w-7)
Step-by-step explanation:
[tex]\frac{w-5}{w-7} and \frac{w+8}{3w}[/tex]
w-7 is a binomial, and 3w is a monomial. Because you cannot put one denominator into the other or multiply both denominators by a number when you have this type of difference where multiplying by a number won't get you the same result, you must multiply them each other.
Therefore:
3w(w-7) would be your LCD.
Answer:
A. 3w (w − 7)Step-by-step explanation:
GivenFractions
(w- 5)/(w-7) and (w + 8)/3wTo findCommon denominatorSolutionWe observe that the fractions can't be simplified any more and they are in the simplest form
Next, the denominators w - 7 and 3w don't have common factors
Therefore the common denominator is the product of denominators:
3w(w - 7)Correct option is A

Steven has £1100.
He pays £530 for a new TV.
His mortgage payment is £480.
How much money does he have left after paying for the TV and
paying his mortgage?
Answer:
£90
Step-by-step explanation:
Total money=£1100
Cost of new tv=£530
Mortage payment=£480
Therefore total money left =1100-(530+480)
=1100-1010=£90

Answer: can it be a fraction?
Step-by-step explanation:
Answer: y = 4/3 + 1/4x
Step-by-step explanation: 6y - 1.5x = 8
Add 1.5x to get y alone, 6y = 8 + 1.5x
Divide everything by 6, y = 8/6 + 1.5x/6

what is y when the equation is x^2 - 3xy -4y^2 =0
Answer:
y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))
Step-by-step explanation:
Solve for y:
-4 y^2 - 3 x y + x^2 = 0
Hint: | Multiply both sides by a term to make the coefficient of y^2 positive.
Multiply both sides by -1:
4 y^2 + 3 x y - x^2 = 0
Hint: | Using the quadratic formula, solve for y.
y = (-3 x ± 5 sqrt(x^2))/8:
Answer: y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))
