Answer:
Step 3
Step-by-step explanation:
Ernesto was doing well until he got to Step 3.
Its a little mistake but that chabges up the entire problem.
Let me explain-
In Step 2: 3(y+7)-2y is showing that you must distribute the 3 to the y and the 7 however Ernesto only did that for the y.
That would be the answer, hopw this helps.
Answer:26 first class stamps and 28 additional.
Step-by-step explanation:
From information given,we can formulate the following equation: 47n +25(54-n ) = 1922
Now we solve for n .
47 + 1350+ 25n =1922
47n -25n =1922- 1350
22n=572
n= 26 .
Therefore 26 first class stamps and 28 additional. 54 total
4/8x - 6 = - 24
First you want to get the x term by itself:
add 6 to both sides:
4/8x = - 18
now isolate x from the numbers:
multiply both sides by 8/4:
x = -36
Given that the first term of the sequence is –1.5, the next term of the sequence would be 3
<h3>How to determine the next term?</h3>
The recursive function is given as:
f(n + 1) = -2f(n)
Substitute 1 for n
f(1 + 1) = -2f(1)
Evaluate
f(2) = -2f(1)
Given that the first term is -1.5, the equation becomes
f(2) = -2 * -1.5
Evaluate
f(2) = 3
Hence, the next term of the sequence is 3

Answer:
The time at which they will all meet at a place together is 350 minutes
Step-by-step explanation:
The time it takes Faiza to cycle the park = 60 seconds
The time it takes Krish to cycle the park = 14 seconds
The time it takes Joe to cycle the park = 25 seconds
Therefore, the time they will all meet at a place together is given by their Lowest Common Multiple as follows;
LCM = 60 × 14 × 25 = 21,000 seconds
Therefore, the time at which they will all meet at a place together in minutes = 21000 seconds/(60)×minute/second = 350 minutes
