Answer:
Their weekly sales would have to be $10,000 before they can be earning the same amount for the week
Step-by-step explanation:
If they are to be earning the same thing each week, it means whatever Toni is earning is what Nicky would be earning.
We proceed by equating their earnings so we would get x;
800 + 0.07x = 600 + 0.09x
Collect like terms
800-600 = 0.09x -0.07x
200 = 0.02x
x = 200/0.02
x = 10,000
Q19) the answer is 4 as 1 kg = 1000 and 1000 divided by 250 is 4
Q20) 3kg as 225 x 2 = 500 plus 800 x 3 = 2400 and 500 + 2400 = 2900 which is closer to 3000g which is 3kg
Q21) the blue and gold macaw as 1kg = 1000g and 800g is closet to that
Answer:
x=9, y=-4. (9, -4).
Step-by-step explanation:
2x+5y=-2
4x+7y=8
--------------
-2(2x+5y)=-2(-2)
4x+7y=8
---------------------
-4x-10y=4
4x+7y=8
--------------
-3y=12
y=12/-3
y=-4
2x+5(-4)=-2
2x-20=-2
2x=-2+20
2x=18
x=18/2
x=9
