Last week, Jack sold x number of hot dogs at the
football game. This week he sold twice as many as
last week, and then he sold 10 more. Write an
expression to show how many hot dogs Jack sold
this week.
Answer:
2x+10
Step-by-step explanation:
Hi there!
To represent last weeks sale, you would have f=x
x= the number of hot dogs he sold last week
Now, to get the expression of this week, you know that he sold TWICE as many as last week, and we know that x represents last week's sale, so you would get 2x.
2 represents twice the sales of the last week, and x represents last week's sales.
But then you also know that he sold 10 more. So he sold twice as many as last week's hot dogs but he also sold 10 more. That's where you get 2x+10
Again, 2x represents twice as many sales this week and the 10 is the 10 more hot dogs he sold.
Really hope this helps!
An expression for hot dogs Jack sold this week is 2x+10.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

But then you also know that he sold 10 more. So he sold twice as many as last week's hot dogs but he also sold 10 more. That's where you get 2x+10

The number of DVD's sold at Fry's Electronics in a month was 920 and the number of DVD's sold decreased by 12 per month. The number of Blu-ray discs sold at Fry's Electronics in the same month was 502 and the number of Blu-ray discs sold increased by 26 per month. Write a system of equations to model th situation. If this trend continues, in how many months will the number of DVD's sold each month equal the number of Blu-ray discs sold each month? How many each disc is sold in that month?
Answer:
11 months
788 disc
Step-by-step explanation:
Let
x = number of months
Fry's Electronics;
= 920 - 12x
Blu-ray discs:
= 502 + 26x
Equate both equations
920 - 12x = 502 + 26x
920 - 502 = 26x + 12x
418 = 38x
x = 418/38
x = 11 months
number of months = 11
Substitute 11 into any of the equation
Fry's Electronics;
= 920 - 12x
= 920 - 12(11)
= 920 - 132
= 788 disc sold in that months

Answer:
A): 22/5 = 4 2/5 in mixed fraction. 22/5 = 4.4 in decimal. B): 0.875
Step-by-step explanation:
Since you can't divide 7/8 it will turn into decimal. If you use calculator, it will be decimal. Basically in order to do long division, you would need to drop down zeros like add zeros if the divisor and dividend don't equal. You keep adding zeros until it's equal. IF it is more likely to be continuous, then you would need to add a repetend on the last digit. For example, 3/1 you can know it would be 1.333333 and so on. Example of how to do it:
550 visitors paid for admission to Hope State Park during one week. Of those 550 visitors, 3/5 of them purchased guide books. How many visitors purchased guide books?
Answer:
the number of visitors purchased guide books is 330 visitors
Step-by-step explanation:
The computation of the number of visitors purchased guide books is shown below;
= Number of visitors × visitors purchased guide books
= 550 × 3 ÷ 5
= 330
Hence, the number of visitors purchased guide books is 330 visitors
Given that slope = -1 and a point (3,-1), write an equation in slope-intercept form of the line?
Answer:
Step-by-step explanation:
point-slope equation of the line: y+1 = -(x-3)
rearrange to solve for y:
y+1 = -x+3
y = -x + 2 slope-intercept form
Answer:
y = -x + 2
Step-by-step explanation:
We are given that a line has a slope of -1 and passes through the point (3, -1)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept
As we are already given the slope, we can immediately plug its value into y=mx+b.
Replace m with -1 in y=mx+b.
y = -x + b (there's no need to write -1 in front of x. If -1 is the coefficient in front of a variable, just writing a minus sign in front of the variable is enough).
Now we need to find b.
As the equation passes through the point (3, -1), we can use it to help solve for b.
Substitute 3 as x and -1 as y.
-1 = -3 + b
Add 3 to both sides
2 = b
Substitute 2 as b in the equation so far.
y = -x + 2
Topic: finding the equation of the line (in slope-intercept form).

The pass mark for a test is 86%.
Steve scores 52 out of 61 marks.
Does he pass the test?
Answer:
He fails
Step-by-step explanation:
Marks = 52/61
Percentage = 52/61 x 100 ~ 85%
Pass amrk =86%
85% < 86%
So , he fails
Answer:
nope

52÷61=0.85
0.85x100=85%
he needs 86% so he does not pass
Write an exponential function in the form y=ab^x that goes through points (0,7) and
(9, 3584).
Answer:y=7(2)^x
Step-by-step explanation:
The exponential function in the form y=ab^x that goes through the given points is f(x) = 7(2)ˣ.
What are Exponential Functions?Exponential functions are functions where the independent variable, x is in the exponent.
The general form of exponential function is,
f(x) = abˣ
The function passes through (0,7) and (9, 3584).
Substituting (0, 7),
7 = a b⁰
7 = a (since b⁰ = 1)
So, a = 7
Function is f(x) = 7bˣ
Now Substituting (9, 3584),
3584 = 7 b⁹
b⁹ = 3584 / 7
b⁹ = 512
b⁹ = 2⁹
b = 2
So the function is f(x) = 7(2)ˣ
Hence the function is f(x) = 7(2)ˣ.

Shawn had a piece of string 1/2 m long. He used 1/3 of it to tie a box. Find the length of the string which was used to tie the box.
Answer:
7/50
Step-by-step explanation:
First we have to find how much string we are going to cut into 5 pieces. We do this by taking 1/5 of 7/8 meter.
1/5 × 7/8 = 7/40
Now we have to subtract this from the original amount...
7/8 - 7/40 =
35/40 - 7/40 =
28/40 = 14/20 = 7/10
Now we divide this remaining string by 5 to find the length of the individual pieces...
7/10 ÷ 5 =
7/10 × 1/5 =
7/50 meter

What is the equation of parabola whose vertex is (h, k)?The equation of the parabola whose vertex is (h, k) is
[tex]y = a(x-h)^{2} + k[/tex]
According to the given question.
We have a graph for the function f(x) and g(x).
[tex]f(x) =x^{2}[/tex]..(i)
⇒ the equation of parabola whose vertex is (0, 0)
Since, we know the standard form of the equation of parabola is
[tex]y = a(x-h)^{2} +k[/tex]
Substitute h = 0 and k = 0 in the above equation.
⇒ [tex]y = a(x-0)^{2} +0[/tex]
⇒ [tex]y = ax^{2}[/tex]..(ii) (where, y = f(x))
On comparing the first two equations we get a = 1.
From the graph we can see that g(x) is a equation of parabola, whose vertex is (0, 2).
Therefore, the equation for red graph is given by
[tex]g(x) =a(x-0)^{2} + 2[/tex]
[tex]g(x) = 1x^{2} +2[/tex] (because a = 1)
⇒ [tex]g(x) = x^{2} +2[/tex]
Hence, option c is correct.
