5 0

Step-by-step explanation:

n = 0 : 2(0) -1 = -1

n = 1 : 2(1) - 1 = 1

n = 2 : 3

n = 3 : 5

n = 4 : 7

n = 5 : 9

sum = -1 + 1 + 3 + 5 +7 + 9 = 25

Problem<br> 1<br> + 10x + 13 = 4
lutik1710 [3]

Answer:

x = -1

Step-by-step explanation:

Equation: 1+10x+13=4

Step 1: Balance both parts of the equation.

1+10x+13=4

(10x)+(1+13)=4

10x+14=4

10x+14=4

Step 2: Reduce 14 from both parts of the equation.

10x+14-14=4-14

10x= -10

Step 3: Split both sides by 10, because \mathrn {10x = -10}.

\frac{10x}{10} = \frac{-10}{10}

10 / -10 = -1

Therefore, x = -1.

Suppose vanilla beans cost $600 per kilogram. Julie bought 9 grams of vanilla beans. Jacques bought 70 grams of vanilla beans.
GenaCL600 [577]
The Correct option is 36.60
Step-by-step explanation:
The key to solving this question lies
around measurement
conversion,specifically converting
grams into its equivalence in
kilograms.
1000 grams equal one kilogram
9 grams=9/1000 kg
9 grams=0.009 kg
70 grams=70/1000 kg 1000 grams equal one kilogram
9 grams=9/1000 kg
9 grams=0.009 kg
70 grams=70/1000 kg
70 grams=0.07 kg
Julie pays=$600*0.009=$5.4
Jacques pays=$600*0.07=$42
Jacques pays $36.60 more ($42-
$5.4) than Julie paid
Option is wrong because that was Jacques pays=$600*0.07=$42
Jacques pays $36.60 more ($42-
$5.4) than Julie paid
Option is wrong because that was
what Julie paid
Option D is wrong because that was
what Jacques paid
Option B is obviously wrong
