3:5=x:50
Therefore 5 ×x = 50
x = 10
Therefore 3 × 10 = 30
therefore 30 blue pens
proof = 30 blue + 50 red= 3+ 5
therefore 80 = 8x
Answer:
5029
Step-by-step explanation:
There is a common difference between consecutive terms, that is
d = - 201 - (- 215) = - 187 - (- 201) = - 173 - (- 187) = 14
This indicates the sequence is arithmetic with sum to n term
= [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = - 215 and d = 14 , then
= [ (2 × - 215) + (46 × 14) ]
= 23.5 (- 430 + 644)
= 23.5 × 214
= 5029
Answer:
the answer may be this: 8 √3
Answer:
it increased 30.36%
Step-by-step explanation
100/56=1.785714286
1.785714286x73=130.35714286
130.35714286-100=30.35714286
30.35714286=30.36%
Hello,
Degre 5==> even number of imaginary roots and odd number of reals.
Real roots must be a divisor of 7.
