The scatter plot below shows the number of pizzas sold during weeks when different numbers of coupons were issued. The equation represents the linear model for this data. y = 3.4x + 43
According to the model, what is the average number of pizzas sold in one night if no coupons are issued?
Question 5 options:
A 43
B 0
C 11
D 21
Answers
Answer:
option: A is correct.
Step-by-step explanation:
We are asked to find the average number of pizzas sold in one night if no coupons are issued.
i.e. we have to find the value of y such that x=0 i.e. no coupon was issued.
We are given a equation which represents the linear model for this data:
y = 3.4x + 43
where y denotes the average number of pizza sold and x denotes the number of coupons issued.
Hence when x=0 we have value of y from the above linear equation as:
y=3.4×0+43=0+43=43
i.e. y=43.
Hence, average number of pizzas sold in one night if no coupons are issued are 43.

A regular 7 sided figure is divided into 7 congruent triangles ,each with a base of 12 inches and a height of 12.5 inches. What is the area of the 7 sided figure.
Answers
A=bxh/2
b=12 inches (the base of the triangle)
h=12.5 inches (the height of the triangle)
When you substitute these values into the formula, you obtain:
A=bxh/2
A=(12 inches)(12.5 inches)/2
A=75 inches²
You already have the area of one triangle. So, you only have to multiply this area by 7, because the seven (7) triangles are congruent, which means that they have the same area:
At=Ax7
At=(75 inches²)(7)
At=525 inches²
What is the area of the 7 sided figure?
The answer is: 525 inches²
Answer:
Step-by-step explanation:
I did (1/2 divided by 12) and then I got 6 so I times it with 12.5 and got 75 then I times it by 7 to get 525

Answers
..lou's will have (x+y)+y=x+2y ...
Tom=x+3y....
Charlie=x+4y.....
now as we know that the combines scones of robbie and Cameron is 3/7 times of total of louis.....
x+(x+y)=3/7 (x+3y+x+2y+x+4y)....solve this ...and this will be your 1st equation...and second equation will be x+x+2y+x+3y+x+4y=60.......And solve both equation simultaneously and then you will have the answers of x and y the put the values of x and y in each of the equation that i have written above for each person

Ivan has 4 hours of Music on his MP3 player jazz makes up 1/6 of the total time how many hours of jazz are on Ivan's MP3 player show your work
Answers
The answer for this problem is 2/3
The hours of jazz are on Ivan's MP3 player, if Ivan has 4 hours of Music on his MP3 player is 2/3 or 0.7 hours.
What is fraction?Only verbal descriptions of a portion of the whole were used to write fractions in ancient Rome. The numerator and denominator of fractions are first written in India with one number above the other but without a line. The line used to divide the numerator and the denominator were only added by Arabs.
Given:
Ivan has 4 hours of Music on his MP3 player,
jazz makes up 1/6 of the total time,
Calculate the hours of jazz on Ivan's MP3 player as shown below,
The hours of jazz are on Ivan's MP3 player = 1 / 6 of the total time
The hours of jazz are on Ivan's MP3 player = 1 / 6 × 4 hours
The hours of jazz are on Ivan's MP3 player = 4 / 6
The hours of jazz are on Ivan's MP3 player = 2 / 3
Thus, the time of jazz is 2 / 3 or 0.7 hours.

What is 312.501 rounded to the nearest whole number? A. 310 B. 311 C. 312 D. 313
Answers
Hope it helps!
In mathematics, the principle of rounding instructs us to look at the decimal part . If it's .5 or higher, we round up; if it's less than .5, we round down. Hence, 312.501 rounded to the nearest whole number is 313.
Explanation:The question pertains to the concept of rounding numbers. In mathematics, rounding means replacing a number with an approximate value that has a shorter, simpler, or more explicit representation. To round 312.501 to the nearest whole number, we look at the decimal part of the number. If the decimal is .5 or greater, we round up; if it's less than .5, we round down. In this case, the decimal part is .501, so we round up to the next whole number.
So, 312.501 rounded to the nearest whole number is D. 313.

Use the elimination method to solve the system of equations.
5x + 2y = 7 −5x + 4y = 5

There are an infinite number of solutions.

There is no solution.
Answers
-5x + 4y = 5
You can immediately eliminate the x-terms and subtract:
2y = 7
4y = 5
-_____
-2y = 2
y = -1
Substitute back to find x:
-5x + 4y = 5
5x + 4(-1) = 5
5x - 4 = 5
5x = 9
x = 1.8
Finally, substitute back to check your work:
5x + 2y = 7 => 5(1.8) + 2(-1) = 7 => 9 - 2 = 7 <--True
-5x + 4y = 5 => -5(1.8) + 4(-1) = 5 => -9 - 4 = 5 <--False

We have to find the sum of (7x-6y) and (x+y)
(7x-6y) and (x+y) are two Algebraic expressions
Sum of two algebraic expressions is also a algebraic expression
So, (7x - 6y) + (x+y) = 7x - 6y + x + y
= 7x + x + y - 6y
= x (7 + 1) + y - 6y
= 8x + y - 6y
= 8x + y ( 1 - 6 )
= 8x + y ( -5 )
