Answer:
y = 8
Step-by-step explanation:
First substitute x with 6 in the equation
2y + 1/3(6) = 18
Multiple 1/3 with 6, which is 2
2y + 2 = 18
Solve the equation by subtracting 2 from both sides
2y + 2 = 18
- 2 - 2
You get 2y = 16, so you divide 2 frm both sides
You get y = 8
Let Lisa's height be x, Ian's be y and Jim's be z
x = 10 + y . . . (1)
y = 14 + z . . . (2)
y + 14 + z + 14 = 170 + x + 14
y + z - x = 170 + 14 - 28 = 156 . . . (3)
From (2), z = y - 14 . . . (4)
Putting (1) and (4) into (3) gives,
y + y - 14 - 10 - y = 156
y = 156 + 24 = 180
Therefore, Ian's height is 180 centimeters
Answer:you need to sell 25 muffin baskets before you will begin to make profit
Step-by-step explanation:
Let x represent the number of muffin baskets that you fill.
Each empty basket will cost $2.50 to purchase and you will fill it with muffins that you have baked.
You have spent $75 on muffin mix ingredients.
Total cost of x baskets filled with baked muffins is
2.5x + 75
If you sell your muffin baskets for $7.50 each, then total amount received for x muffin baskets would be 7.5x
At the point where you begin to make profit,
2.5x + 75 = 7.5x
7.5x - 2.5x = 75
5x = 75
x = 15
Answer:
168
Step-by-step explanation:
Start by finding the whole prism's volume. 9 x 3 x 8 = 216 Then find the volume of the missing part. 8 x 6 x 1 = 48. Subtract the missing volume from the whole volume. 216 - 48 = 168
