The answer for part (3) is $1.5 each fry, answer for part (5) is 10 four-person table, and answer for part (7) is $3.5 each order of ice cream.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
3)
Let x be the cost of each fry.
4×5 + 3x = 24.50
20 + 3x = 24.50
3x = 4.5
x = $1.5 each fry
5)
Let x be the number of tables for a four-person.
Couple means two persons.
56 - 2×8 = 4x
4x = 40
x = 10 four-person tables
7)
Let x be the cost of each order of ice cream:
12 + 6x = 33
x = $3.5 each order of ice cream.
Thus, the answer for part (3) is $1.5 each fry, answer for part (5) is 10 four-person table, and answer for part (7) is $3.5 each order of ice cream.

Write an equation that represents the tile pattern in the table below
Answer:
y=3x+2
Step-by-step explanation:
First find the slope or m in the line of equation y=mx+b
to find slope you need two points, plug in to y2-y1 / x2-x1
so lets use points (0,2) (1,5)
5-2 / 1-0 = 3
m=3
we have y=3x + b
now we find b by pugging in a point, let's use (0,2)
2 = 3(0) + b
b= 2
y=3x+2

A total of 600 advertisements were sold for a certain magazine. If 20 percent of the first 200 sold were in color, 40 percent of the next 300 sold were in color, and 80 percent of the last 100 sold were in color, what percent of the 600 advertisements were in color?
Answer:
40%
Step-by-step explanation:
First, find how many of the first 200 were in color:
200(0.2)
= 40
Then, find how many of the next 300 were in color:
300(0.4)
= 120
Find how many of the last 100 were in color:
100(0.8)
= 80
Then, add these all together to find how many were in color:
40 + 120 + 80
= 240
Then, divide 240 by 600 to find the percent that were in color:
240/600
= 0.4
So, 40% of the 600 advertisements were in color
josephin is going on a run around the lake. she knows the distance around the lake. but she would like to complete her run in a certain amount of time. josephine knows she can use the formula d= rt.
which equation correctly rearranges the formula to find the time it will take her to run around the lake?
look at picture and tell me if it is a, b, c, or d.
Answer:
A. [tex]t = \frac{d}{r}[/tex]
Step-by-step explanation:
Given
[tex]d = rt[/tex]
Required
Determine the time
From the question, we understand that:
[tex]d = distance[/tex]
[tex]r = rate[/tex]
[tex]t = time[/tex]
This question implies that we make t the subject of formula.
[tex]d = rt[/tex]
Divide both sides by r
[tex]\frac{d}{r} = \frac{rt}{r}[/tex]
The equation becomes:
[tex]\frac{d}{r} = t[/tex]
Reorder the equation.
[tex]t = \frac{d}{r}[/tex]
The correct option is (a) [tex]t = \frac{d}{r}[/tex]
A student took two national aptitude tests. The national mean and standard deviation were 325 and 100, respectively, for the first test, and 50 and 6, respectively, for the second test. The student scored 425 on the first test and 65 on the second test. Use z-scores to determine on which exam the student performed better relative to the other test takers. first exam
Answer:
Second test
Step-by-step explanation:
Given that :
FIRST TEST
Mean (m) = 325
Standard deviation (s) = 100
Score (x) = 425
SECOND TEST
Mean (m) = 50
Standard deviation (s) = 6
Score (x) = 65
Express both scores as standardized scores:
Zscore = (x - m) / s
First Score :
Zscore = (425 - 325) / 100
Zscore = 100/100 = 1
SECOND SCORE :
Zscore = (65 - 50) / 6
Zscore = 15 / 6 = 2.5
Student performed better on second test :
Zscore second > Zscore first

What is Decimals numbers?Decimal numbers are numbers which has basically a whole number part and a fractional or decimal part after a point called decimal point.
Decimal number system describes the base 10 number system.
Here we have to find the difference of 1 - 0.4308.
Here, the number is 0.4308, which is a decimal number.
Write 1 as the decimal number as 1.0000
