Answer:
x = -2/7 or
x = 6/7
Step-by-step explanation:
|7x-2| + 3 = -1 subtract 3 from both sides
|7x-2| = -4 now there are two probabilities
7x-2 = -4 or
7x-2 = 4 if first probability the value of x would be:
7x-2 = -4 add 2 to both sides
7x = -2 divide both sides by 7
x = -2/7 for the second probability the value of x would be:
7x-2 = 4 add 2 to both sides
7x = 6 divide both sides by 7
x = 6/7
Answer: 1350
Step-by-step explanation:
Here is the correct question.
Raquel can type an average of 63 words per minute. Rick can type 73 words per minute. how many more words can Rick type than Raquel in 135 minutes? Jared chose B as the correct answer. How did he get that answer? Jared said the answer is 4599. How did he get that answer?
Rick's word per minute= 73
Raquel's word per minute= 63
Ricks word in 135minute= 73×135 = 9855
Raquel's word in 135 minutes=63×135 = 8505
=9855 - 8505
= 1350
Rick can type 1350 more words than Raquel in 135 minutes.
Jared's answer is wrong. He got the answer by multiplying 63 by 73 which gives 4599.
Answer:
Step-by-step explanation:
Important things to note:
- The 5 and 3 are multiplied together because they are both regular numbers
- The and are multiplied together because they are they same variable
- When multiplying values with exponents, the exponents are added together
The amount earned from the local account must be greater than that of the online account.
Amount from local account = 6,500(1.0145)ⁿ
Amount from online account = 6,500(1.0225)ⁿ - 4x
Where n is the number of years and x is the number of ATM withdrawals.
6,500(1.0145)ⁿ > 6,500(1.0225)ⁿ - 4x
4x > 6,500[(1.0225)ⁿ - (1.0145)ⁿ]; n = 1
x > 13
The number of withdrawals must exceed 13.
The answer is C.
