There’s not actually a question. But I might be able to help if u show the full problem
Answer:
15205.3
Step-by-step explanation: H=30 R²=484 3.14=π →= rounded up to tenth V = Volume
<em><u>formula (no numbers): H x R² x π ÷</u></em><u> </u>
<u> (or 3) </u><em><u>= V</u></em>
<u><em>how i got the answer : 30 x 484 x 3.14 ÷ 3 = 15205.31 → 15205.3</em></u>
The second equation, its setup is correct
Do each equation individually and compare if they are the same end answer in each question. which ever one is unequal than that is the answer
Answer:
(8, 2 )
Step-by-step explanation:
Given the 2 equations
x + 4y = 16 → (1)
- x + 3y = - 2 → (2)
Adding the 2 equations term by term will eliminate the x- term
0 + 7y = 14
7y = 14 ( divide both sides by 7 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (1)
x + 4(2) = 16
x + 8 = 16 ( subtract 8 from both sides )
x = 8
solution is (8, 2 )
