Answer:
D
Step-by-step explanation:
out of the choices
A) 2x-y=-2
3x+2y=-10
B) x+4y=3
2x+5y=3
C) 2x+3y=5
x-4y=-14
D) 3x+4y=15
x+y=5
only the system in D has a solution of x=5 and y=0
solve by substitution x+y=5 so x=5-y
plug into the other equation so 3(5-y)+4y=15
distribute 15-3y+4y=15 then minus 15 on both sides and combine like terms
so y=0 then put that value back into the other equation
so x+y=5 equals x+0=5 so x=5 this means the solution to the system of equations is the point (5,0)
Hope this helps! :)
31 seconds it will take to get around without it stopping
C(8)=29 you have to plug in 8 for n in the equation and solve. Hope this helps!!!
Answer:
your answer is correct -7,-2
Step-by-step explanation:
A.) First, you find the total sales. $2030 + $1540 + $1800 = $5370. Then, divide each with the total. The answer would be:
Lola: 203/537
Ahmed: 154/537
Tommy: 60/179
b.) Divide 100 by 3 for equal shares. Each person receives $33.3.
