Answer:
Step-by-step explanation:
5x=y+6 --------- equ 1
2x-3y=4 -------- equ 2
5x - 6 = y
y = 5x - 6
substitute in equ 2
2x-3(5x - 6) =4
2x - 3*5x + 3*6 = 4
2x - 15x + 18 = 4
- 13x = 4 - 18
-13x = -14
x = -14/-13
x = 14/13
substitute in equ 1
5*14/13 = y+6
70/13 - 6 = y
y = ( 70 - 78)/13
y = -8/13
Answer:
Probably play video games and drink hot chocolate. Maybe go sledding to.
Step-by-step explanation:
picture unclear because it is to find the sum of consecutive numbers 1 to 100, you multiply the number of sets (50) by the sum of each set (101): 101(50)=5050.{\displaystyle 101(50)=5050.} So, the sum of consecutive number 1 through 100 is 5,050 .
The break-even point is when there is no profit and no loss. Given the two equations for cost and revenue, we simply have to equate the two equations to solve for the unknown value, n. This is shown below:
C = 20n + 134000
R = 160n
R = C
160n = 20n + 134000
140n = 134000
n = 957.14
Among the choices, the nearest answer is D. 957.
