Answer:
Some examples of linear equations in two variables are: 1.2s + 3t = 5, p + 4q = 7, πu + 5v = 9 and 3 = 2 x – 7y. Note that you can put these equations in the form 1.2s + 3t – 5 = 0, p + 4q – 7 = 0, πu + 5v – 9 = 0 and 2 x – 7y – 3 = 0, respectively.

Taylor has dd dimes and qq quarters. She has a maximum of $4 worth of coins altogether. Write this situation as an inequality.
Answer: .10d+.25q<_ 4
Step-by-step explanation:
d= dimes and q = quarters
dimes are worth .10 and quarters are worth .25
The inequality for the given situation is
0.1d + 0.251 ≤ 4
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
10 dimes = 1 dollar
1 dime = 0.1 dollar
4 quarters = 1 dollar
1 quarter = 0.25 dollar
Now,
The maximum amount is $4.
So,
0.1d + 0.251 ≤ 4
Thus,
The inequality is 0.1d + 0.251 ≤ 4.

How can percents show proportional relationships between
quantities and be used to solve problems?
Answer:
By testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin
Step-by-step explanation:
Percentages are simply the measures of a quantity over a hundred (100), while proportional relationships are relationships that have a constant equivalent ratio
Solving proportional relationships using percentage
A proportional relationship is represented as:
[tex]y = kx[/tex]
Where k represents the proportionality constant, and x and y are the variables (or quantities).
Using percentages, then k has to be represented as a percentage.
Take for instance,
20 is 5% of 1007 is 5% of 140When the above instance are represented as a proportional relationship, we have:
[tex]y = 5\% \times x[/tex]
Such that
[tex]k = 5\%[/tex]

company should Sally go with if she wishes to choose the cheapest?
Answer:
car help
Step-by-step explanation:
In order to determine which type of house insurance would be considered as cheapest first it is necessary to determine either monthly or either weekly
As we know that
Generally in the month there is a 4 weeks
So For Car Help, the monthly would be
= $8.60 × 4
= $34.40
And for Car safety, the quoted price is $36.10 per week
So according to the above calculation the car help would be choose as the cheapest

Cost to store: ?
Markup: 15%
Selling price: $85.10
Answer:
115% = 85.10
divide both sides by 115 to find 1%
1% = 0.74
now multiply both sides by 100 to find 100%
100% = 74
cost price = $74

Answer:
6
Step-by-step explanation:
you want to create two equations for each situation so if v=number of students that can fit in a van and c=number of students that can fit in a car then you can create the equations 3v+1c=22 and 2v+4c=28
then you want to make both equations equal to c
so for the first one you subtract both sides by 3v and you get c= -3v+22
and for the second one you subtract 2v from both sides and end up with 4c=-2v+28 and then divide both sides by 4 leaving you with c= -1/2v+7
then you make both of those equations equal to each other and solve for v
so -3v+22= -1/2v+7 and you end up with v=6
therefore, each van can hold 6 students

Write an equation to fond the nth term of each sequence. Then find a9. 5,20,80
Answer: a₉ = 327,680
Step-by-step explanation:
This seems to be a geometric sequence.
The recursive relation for this type of sequence is:
aₙ = aₙ₋₁*r
Where r is a constant.
Then we also have:
aₙ/aₙ₋₁ = r.
then we can find the value of r if we take the quotient of different consecutive terms, for example, the quotient of the second and firs term is:
r = 20/5 = 4
And the quotient between the third and second term is:
r = 80/20 = 4
Then we can conclude that r = 4.
And also, the n-th term of this sequence can be written as:
aₙ = a₁*r^(n - 1)
such that:
a₁ = 5
r = 4
Then the n-th term of this sequence is:
aₙ = 5*(4)^(n - 1)
Then the term a₉ can be found if we just replace n by 9 in the above equation:
a₉ = 5*(4)^(9 - 1) = 5*(4)^(8) = 327,580

UD = ?
Answer:
UD = 20
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the external part and the entire secant, that is
12² = 7.2(7.2 + CD)
144 = 7.2² + 7.2CD
144 = 51.84 + 7.2CD ( subtract 51.84 from both sides )
92.16 = 7.2CD ( divide both sides by CD )
12.8 = CD
Thus
UD = UC + CD = 7.2 + 12.8 = 20

Mickey said that 45.7654 rounded to the nearest thousandth is 45.765 and Nicole said that it was 45.766. Who is correct and why?
Answer:
Mickey
Step-by-step explanation:
Mickey is correct because if you look at the number 45.7654 whenever you round to the nearest thousandth it'll be 45.765
5 is the thousandth place so look to the right. If the number to the right is greater than 5 it'll round to 47.766 but since it's a four ti rounds down.

True or False: The starting value of an exponential function determines if it
is exponential growth or exponential decay. *
Answer:
True.
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
f(x) = ab^x
The starting value is a and it is the y intercept, not the starting value. Whatever is in the b value determines if it's exponential growth or exponential decay.
