Answer:
48
Step-by-step explanation:
If she already has 22 and she can buy 2 for $1 and she has $13, multiply 2 by 13 to get how many she can buy, or 26. Then add the amount she already owns to how many she can buy to get how many she can own, or 48.
Answer:
slope = 2
Step-by-step explanation:
Pick two points to find the slope. (1, 2) and (3, 3)
From the left (1, 2) to (3, 3), it goes up 2 units and to the right 1 unit.
We can plug this into the slope equation which is rise/run
2/1 = 2 = slope
Answer:
Coin a is 33 and coin b is 11
Step-by-step explanation:
Answer:
Subtract $4.60 from 0.05
Step-by-step explanation:
X2 + y2 - 14x + 10y = 250
x2 -14x + 49 - 49 + y2 + 10x + 25 - 25 = 250
(x - 7)^2 - 49 + (y+5)^2 - 25 = 250
(x-7)^2 + (y+5)^2 = 250 + 49 + 25
(x-7)^2 + (y+5)^2 = 324
Therefore the radius, r
r = 324^0.5
r = 18
