Answers

aritmetic average=sum of values / number of values
x=number of meals that the cafetery sold in Friday.

aritmetic average=69
number of days=5

69=(64+71+73+60+x) / 5
69=(268+x) / 5
69*5=268+x
268+x=345
x=345-268=77

Answer: C. 77 meals.

Alyssa bought a soft drink of four dollars and seven candy bars. She spent a total of 39 dollars. How much did each candy bar cost?

Answers

answer is $5. if the drink was $4 and the total was $39 then subtract 39-4 u get 35. then do 35/7 because there are 7 bars, and we wanna figure out of much THOSE where, thus is why we subtracted 4.

Value of x in the solution to the system of equations.
6x+3y=13
3x-y=4

Answers

The two easiest ways to solve a system of equations (in my opinion) are to add the equations together while getting rid of a variable, or solving for a variable in one equation and plugging it into another. The latter is the method I will use.

3x - y = 4 (solve for y)
3x = 4 + y
3x - 4 = y
y = 3x - 4

Now we can plug y into the other equation:
6x + 3y = 13
6x + 3(3x - 4) = 13
6x + 9x - 12 = 13
15x = 25
x = 25/15
x = 5/3
The answer is x = 5/3

If you ever needed to find y as well, you can plug this into either equation to find y.
3x - y = 4
3(5/3) - y = 4
5 - y = 4
y = 1

How do you do 4and 6 plssss help me

Answers

Answer:

4. y+3=-1/3(x-9) 6a. 15x-y=0 6b. $150

Step-by-step explanation:

Point slope form formula: y-y1=m(x-x1)

Includes origin and point (9,-3)

m= y2-y1/x2-x1

-3-0/9-0= -3/9=-1/3

slope= -1/3

Since we already have the point (9,-3),

enter the information above into the point slope form formula.

y-(-3)=-1/3(x-9)

y+3=-1/3(x-9)

3h--> $75

1h--> $15

Standard form: Ax + By = C

m(slope)=15

y=15x

y-15x=0

-15x+y=0

15x-y=0

10 hours of work---> $150
