Answer:
[tex] 6.4 * 10^{3} km[/tex]
Step-by-step explanation:
Scientific notation can be defined as a way of expressing and writing a very small or large real number in decimal form. Generally, to use the scientific notation, we will multiply the real number by a power of 10.
Given that the length of Amazon River is 6,400 kilometers.
[tex] \frac{6400}{1000} = 6.4[/tex]
[tex] 1000 = 10^{3}[/tex]
Therefore,
6, 400 kilometers = 6.4 × 10³ kilometers.

Step 1: Add -3 to both sides.
|x+1|+3+−3<4+−3
|x+1|<1
Step 2: Solve Absolute Value.
|x+1|<1
We know x+1<1 and x+1>−1
x+1<1(Condition 1)
x+1−1<1−1(Subtract 1 from both sides)
x<0

Step-by-step explanation:
Nilda has $250 in her savings account. She plans to save $15 per week from her salary. Iona has only $200 in her account but can save $20 a week from her paycheck. How many weeks will it take before the amount in each savings account is the same?
Answer: 10 weeks
Step-by-step explanation:
Nilda's money = 250 +15x being x the number of weeks that have passed
Lona's money= 200+20x
If they have the same amount, then
250+15x=200+20x
250-200=(20-15)x
50=5x
50/5=x
10=x
Answer:
10 weeks
Step-by-step explanation:
Nilda's money = 250 + 15x
Lona's money = 200 + 20x
250 + 15x = 200 + 20x
250 - 200 = (20 - 15)x
50 = 5x
10 = x
10x-5y=20 solve for x

16r6sc/8r2s6 Which expression is equivalent to the given expression? Assume the denominator does not equal zero. A. B. C. D.
Answer:
B.
Step-by-step explanation:
The required expression is equivalent to the given expression is C.
An equivalent expression for 16r6sc/8r2s6 is to determine.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Numerator = it is the term positioned above in the ratio
Denominator = it is the term positioned below in the ratio
Here,
= 16r6sc/8r2s6
Factored 16 into 8 * 2
= 8*2r6sc/8r2s6
Rearrange the numerator in order to simplify relative to denominator.
=8r2s6c/8r2s6
8r2s6 are common in the denominator and the numerator of the ratio denominator does not equal zero so it implies
=c/1
Thus the required expression is equivalent to the given expression is C.
