Aiden buys ice cream and apples at the store.
He pays a total of $15.05.
• He pays a total of $3.80 for the ice cream.
• He buys 3 bags of apples that each cost the same amount.
Write and solve an equation which can be used to determine x, how much each bag
of apples costs.

Answers

Answer 1

Answer:

Equation: y = 3x + 3.80

Cost of each bag: $3.75

Step-by-step explanation:

y = 3x + b

y = $15.05

x = cost of each bag

b = $3.80

3 = # of bags

15.05 = 3x + 3.80

11.25 = 3x

3.75 = x

Answer 2

The equation to determine x is y = 3x + 3.8

and cost of each apple bag is $3.75.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Total amount paid by Aiden = $15.05

Total amount paid for ice cream =  $3.80

Number of bags of apple = 3

So if x is the amount of each apple bag and y is the total amount paid by Aiden,

So,Cost of apple bags = 3x

And total amount = 3x + 3.8

or y = 3x + 3.8

this is the equation to determine x.

Now since, total amount paid is $15.05

⇒ 15.05 = 3x + 3.8

or,3x = 15.05 - 3.8

or 3x = 11.25

⇒ x = 11.25/3

⇒ x = $3.75

Thus,the equation to determine x is y = 3x + 3.8

and cost of each apple bag is $3.75.

f(x)

m = y - y1

x - x1

m = 2 - 0

3 - 2

m = 2

y - y1 = m(x - x1)

y - 0 = 2(x - 2)

y = 2x - 4

f(x) = 2x - 4

g(x)

(2/3, 0) and (1, 2)

m = y - y1

x - x1

m = 2 - 0

1 - 2/3

m = 6

y - y1 = m(x - x1)

y - 2 = 6(x - 1)

y = 6x - 4

g(x) = 6x - 4

since both equations are linear that means the graphs will be straight lines with y-intercept being -4 for both of the graphs.

if,

g(x) = f(k*x)

f(x) = 2x - 4

f(k*x) = 2k*x - 4

6x - 4 = 2k*x - 4

6x = 2kx

6 = 2k

k = 3.

Answer:

Step-by-step explanation:

One of the things you should keep in mind about parallel lines is that there are 8 angles in this configuration.

4 are equal to one value

and 4 other angles which are the supplements to the first four. If you know the value of one of the 8 angles, you know the value of the other seven.

So angles (8) 6 4 and 2 are all 82 degrees.

Angles 1 3 5 7 and all equal to 180 - 82 = 98

Number 8 is given as 82. It's the red number.

number 6 is vertically opposite number 8 so those two are equal

Number 6 is an alternate interior angle to 4. Those two are equal.

Number 2 is number 4s vertically opposite angle. The others are all done somewhat the same way.

Answers

plug your coordinate points into the equation for slope (left corner or the paper)

multiply by the denominator on both sides of the equation

x-6 cancels out and leaves y-23=3(x-6)

multiply x and -6 by 3

add 23 to both sides to isolate y

Once converted, 75% is actually .75

At this point you can move the decimal place two place up, and put it over 100, in a fractal form

75/100  

You can then simplify this to

You can then use this fraction as a conversion factor with any number, for example if we took the number 8

A meteorologist says that there is a 50% greater chance of rain than no rain on Wednesday. What is the probability that it will rain on Wednesday?

Answers

Answer:

2/3

Step-by-step explanation:

The probability that it will rain on wednesday will be 0.75.

What is a expression? What is a mathematical equation? What is Probability?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. The formula to calculate the probability of occurrence of an event 'A' can be written as -  

P(A) = n(A)/n(S)

where -

n(A) = Number of outcomes favorable to event A.

n(S) = Total number of outcomes.

We have a meteorologist who says that there is a 50% greater chance of rain than no rain on Wednesday.

Assume that the probability that it will rain on wednesday be [x]. Now, we can write -

P[R] = P[N.R.] + 1/2

P[R] + P[R] = P[N.R.] + P[R] + 1/2

2 P[R] = 1 + 1/2

2 P[R] = 1.5

P[R] = 1.5/2

P[R] = 0.75

Therefore, the probability that it will rain on wednesday will be 0.75.
