Frank's Auto Corner recorded its sales for the second quarter (April, May and June) of 1999. April sales were 89 cars, May sales were 98 cars, and June sales were 115 cars. During the same quarter in the previous year, 1998, the total sales were 287 cars. How many cars were sold at Frank's Auto Corner during the second quarter of 1999? How many more cars were sold during the second quarter in 1999 than in the second quarter of 1998? Explain how you got your answer.
The number of cars sold at Frank's Auto Corner during the second quarter of 1999 is 302 cars.
The number of cars sold by which 1999 sales exceeds 1998 sales is 15 cars
What is the number of cars sold in second quarter of 1999?
The number of cards sold by Frank's Auto Corner in the second quarter of 1999 is the sum of April sales, May sales and June sales as provided in the scenario given, hence, we just need to sum up the three figures to ascertain total number of cars sold
cars sold in second quarter 1999=89+98+115
cars sold in second quarter 1999=302 cars
The difference between the number of cars sold in second quarter of 1999 over that sold in the second quarter of 1998 is computed by taking the difference between 302 cars and 287 cars
difference in car sales=302-287
difference in car sales=15 cars

what is 58,413,000,000 in scientific notations
Answer:
[tex]\huge\boxed{58,413,000,000=5.8413\cdot10^{10}}[/tex]
Step-by-step explanation:
The scientific notation:
[tex]a\cdot10^k[/tex]
where
[tex]1\leq a<10,\ k\in\mathbb{Z}[/tex]
We have the number:
[tex]58,413,000,000[/tex]

There are 625 students in Weaver Junior High School. Jimmy surveyed 30 students in his English class regarding their favorite subject. Twenty-four of the students responded that they liked history best. If his class is representative sample of the entire school, how many students in the school could Jimmy predict would choose history as their favorite subject?
24 of the 30 students surveyed liked history.
24/30 = 0.8 = 80% of the students surveyed liked history.
Multiply total students by 80%
625 x 0.8 = 500
500 of the total students like history.
The number of students in the school could Jimmy predict would choose history as their favorite subject is 500.
Calculation of the number of students:Since
There are 625 students in Weaver Junior High School. Jimmy surveyed 30 students in his English class regarding their favorite subject. Twenty-four of the students responded that they liked history best.

give the equation of the x- axis and identify the type of line it represents (vertical or horizontal ).
___Fill_in_blank_here_______________________________________
Answer:
Equation of x-axis is y=0, it is a horizontal line.
Step-by-step explanation:
We need to find the equation of the x- axis and type of line it represents (vertical or horizontal ).
On the x-axis, the value of y is always 0 and the value of x can be and real number. Since y is free from x and its value is 0, therefore the equation of x-axis is
[tex]y=0[/tex]
Value of y remains same. So, it represents a horizontal line which intersects the y-axis at 0.
Therefore, equation of x-axis is y=0, it is a horizontal line.

Diego's age d is 5 more than 2 times his sister's age s. This situation is represented
by the equation d = 2s +5. Which equation is equivalent to the equation d = 2s +5?
a. d = 2(s+5)
b. d - 5 = 2s
C.
d - 2 = s +5
d. = 5+5
Answer:
d-5=2s
Step-by-step explanation:
Diego's age d is 5 more than 2 times his sister's age s.
The equation used to represent it is :
d = 2s +5
We need to find the equivalent equation for the above equation.
If we take 5 to LHS of the equation, it will become -5 such that,
d-5=2s
Hence, option (b) is the equivalent equation.

determine the x-intercept and y-intercept of the following linear equations
standard form and show you did it
Answer:
Step-by-step explanation:
the x intercept takes coordinate (x,0)
the y intercept takes coordinate (0,y)
x intercept y intercept
40: x+y=5 (5,0) (0,5)
x=0 , y=5, when y=0 x=5
41: x-y=5 (5,0) (0,-5)
x=0, -y=5 then y=-5, when y=0, x=5
42: 3x+4y=12 (4,0) (0,3)
x=0, 4y=12⇒y=12/4⇒y=3
y=0, 3x=12⇒x=12/3⇒x=4
43: 2x+3y=6 (3,0) (0,2)
x=0 , 3y=6⇒y=6/3=2
y=0 ,3y=6 ⇒ y=6/3 ⇒y=2
44: 3x+4y=-24 (-8,0) (0,-6)
x=0 , 4y=-24⇒y=-24/4 ⇒ y=-6
y=0 , 3x=-24⇒ x=-24/3⇒x=-8
45: 1/3x+2/3y=5/6 (5/2,0) (0,5/4)
x=0 , 2/3 y=5/6 ⇒12y=15 ⇒ y=15/12 ⇒y=5/4
y=0 , 1/3 x=5/6 ⇒6x=15 ⇒x=15/6 ⇒x=5/2
46: x=-2 (-2,0) no y intercept
it is vertical line , there is no y intercept
47: y=15 no x intercept (0,15)
horixzontal line, no x intercept
48: 3x-7y=8 (8/3,0) (0,-8/7)
x=0 , -7y=8 ⇒y=-8/7

Olivia is going to an amusement park. The price of admission into the park is $40, and once she is inside the park, she will have to pay $4 for every ride she rides on. How much money would Olivia have to pay in total if she goes on 13 rides? How much would she have to pay if she goes on r rides?
Cost for 13 rides:
Cost for r rides:
Answer:
Cost for 13 rides: $92
Cost for r rides: I am guessing it would be 40+4r
Step-by-step explanation:
If you automatically pay 40 dollars to get in, then that is the constant, and paying 4 dollars per ride is a coefficient, so that would be multiplied by how many rides you go on, the variable. Once you plug those into the equation above, you would get 92 dollars for the thirteen rides.
Tyler bought a book for $15.00. He had a coupon for 20% off his purchase. How much was the book after the discount? *
Answer:
The book was $12 after the 20% discount
Step-by-step explanation:
Recall that 20% corresponds to the decimal fraction 0.20.
Thus, the price of the book after discount is found by multiplying $15 by
1.00 - 0.20, or 0.80:
0.80($15) = $12

In a certain region, 6% of a city’s population moves to the surrounding suburbs each year, and 4% of the suburban population moves into the city. A 2019 census measures 10,000,000 residents in the city and 800,000 in the suburbs. (a) Set up a difference equation (of the form ~xn+1 = A~xn) that describes this situation, where ~x0 is the initial population in 2019. (b) Estimate the populations in the city and suburbs two years later, in 2021.
Answer:

Step-by-step explanation:
Following are the differential equation:

In equation:
[tex]\to t = 0, \ as \ 2019\\\\\to Ct = 10,000,000 \\\\\to St = 800,000,000\\[/tex]
[tex]\to P(C, S)1 = (0.94Ct + 0.04St, 0.96St + 0.06Ct) \\\\[/tex]
[tex]= (0.94(10000000) + 0.04(800000), 0.96(800000) + 0.06(10000000))\\\\ = (9,400,000 + 32,000), (768,000 +6000000))\\\\ = (9432000, 1368000)[/tex]
[tex]\to P(C, S)2 = (0.94(9432000) + 0.04(1368000), 0.96(1368000) + 0.06(9432000))[/tex]
[tex]=(8,866,080 + 54,720), (1,313,280 + 565,920)\\\\=(8,920,800, 1,879,200)[/tex]

To find:
The reason for each statement.
Solution:
We have,
[tex]7(x+1)+11x=-2x-5[/tex]
Using distributive property, we get
[tex]7x+7+11x=-2x-5[/tex]
On combine like terms, we get
[tex]18x+7=-2x-5[/tex]
Using addition property of equality, add 2x on both sides.
[tex]20x+7=-5[/tex]
Using subtraction property of equality, subtract 7 from both sides.
[tex]20x=-12[/tex]
Using division property of equality, divide both sides by 20.
[tex]x=-\dfrac{12}{20}[/tex]
[tex]x=-\dfrac{3}{5}[/tex]
Therefore, the required reasons are:
2. Distributive property
3. Combining like terms
4. Addition property of equality
5. Subtraction property of equality

-7x + 2y = 4
Answer:
y = 9
Step-by-step explanation:
Given
- 7x + 2y = 4 ← substitute x = 2 into the equation
- 7(2) + 2y = 4
- 14 + 2y = 4 ( add 14 to both sides )
2y = 18 ( divide both sides by 2 )
y = 9
Solution is x = 2, y = 9
