Answer:
x = 8 , y = 3
Step-by-step explanation:
3x + 2y = 30
3x - y = 21 -> y = 3x - 21
3x + 2 (3x - 21) = 30
3x + 6x - 42 = 30
3x + 6x = 30 + 42
9x = 72
x = 72/9 = 8
y = 3*8 - 21 = 24 - 21 = 3
∴ x = 8 & y = 3
Answer:
GCF of 3 and 6 is 3.
LCM of 3 and 6 is 6.
Step-by-step explanation:
Answer: B (3 cups)
Step-by-step explanation:
Add 2 cups + 1 cup together, and you get 3 cups. C is incorrect (in this scenario) because it doesn’t describe what measurement it’s in.
Answer:
y = 1/2x + 3
O f(x)= 1/2x+3
Step-by-step explanation:
f(x) = 2x - 6
y = 2x - 6
x = 2y - 6
2y = x + 6
y = (x + 6)/2
y = 1/2x + 3
