Answer:
4
Step-by-step explanation:
If ten people each get three slices, they will need 30 pieces.
10 x 3 = 30
Each pizza has 8 slices, so we divide 30 by 8 to get the number of pizzas needed.
30 / 8 = 3.75
You can't buy 3.75 pizzas, so you must get 4 to ensure everyone gets enough.
The first one is A and then the next one I believe should be 210 for both
Answer:
<u>10</u>
Step-by-step explanation:
Let the missing side be 'x'.
Using Pythagorean Theorem, we can find the missing side.
- x² + 8² = (2√41)²
- x² + 64 = 4(41)
- x² + 64 = 164
- x² = 100
- x = <u>10</u>
Answer:
y=-2x-3
Step-by-step explanation:
subtract 4x from both sides
4x-4x+2y=-6-4x=
2y=-6-4x
divide both sides by 2
-6/2 and -4x/2
simplify
hope this helps
