Given parameters:
x = 150 minus 6 y
Interpreting this gives;
minus = subtraction = -
x = 150 - 6y
Now bring the variables together;
x + 6y = 150
The option that matches with this equivalent.
The other choices are wrong;
a, x + 150 = 6 y
x - 6y = 150 wrong
c. 2x + 3y = 75 mulitply through by 2;
2(2x + 3y) = 2(75)
4x + 6y = 150 wrong
d. 2x - 3y = 75
Multiply by 2;
2(2x -3y) = 2(75)
4x - 6y = 150
Answer:
(x - 7)^2 + (y - 2)^2 = 5^2
Step-by-step explanation:
Center at (7, 2); radius 5
Adapt (x - h)^2 + (y - k)^2 = r^2 to this situation. Replace h by 7, k by 2 and r by 5:
(x - 7)^2 + (y - 2)^2 = 5^2
Answer:
Each batch of scones needed 0.67 kg of flour
Step-by-step explanation:
16.45 - 6.4 = 10.05kg (remaining)
15 batches = 10.05kg
1 batch = 0.67kg
