Answer:
87.96 square inches
Step-by-step explanation:
The soup can is a cylinder, and we can find how many square inches the label will take up by finding the lateral surface area
Use the formula, LA = 2rh
The diameter is 4 inches, so the radius is 2 inches
Plug in the radius and height into the formula, and solve:
LA = 2rh
LA = 2(2)(7)
LA = 28
= 87.96
So, the label will take up approximately 87.96 square inches

Answer:
The number of cards Frank has is 18 and the number of cards his friend has is 24.
Step-by-step explanation:
<u><em>The correct question is </em></u>
Two friends are collecting cards. Frank has 6 more than half the number of cards as his friend. Together they have 42 cards. How many cards does each friend have?
Let
x ----> the number of cards that Frank has
y ----> the number of cards that his friend has
we know that
Together they have 42 cards
----> equation A
Frank has 6 more than half the number of cards as his friend
---> equation B
Solve the system by substitution
Substitute equation B in equation A
solve for y
<em>Find the value of x</em>
therefore
The number of cards Frank has is 18 and the number of cards his friend has is 24.
Answer:
Step-by-step explanation:
6. Use PEMDAS
-3 x (7 + (-3)*2) / 3
-3 x (7 + 9) / 3
-3 x 16 / 3
-48 / 3
-16
7. 9 (x) = -63
X = - 63 /9
X = -7
