This the only option to find x since doing the other way like 3x + 2 = 3x + 2 gives it an infinite solution.

4x - 1 = 3x + 2

-3x       -3x

1x - 1 = 2

   +1    +1

1x = 3

---   ----

1       1

x = 3

Check:

4(3) - 1 = 3(3) + 2

12 - 1 = 9 + 2

11 = 11

Jezebel is planning a party at the skating rink. The cost for each person attending is $3.50 for skate rental and $5.00 for food
SashulF [63]

Answer:

The inequality that could be used is 8.50p≤300 and the greatest number of people that can attend is 35.

Step-by-step explanation:

From the information provided, you can write an inequality where total cost for people attending at the party should be less than or equal to $300:

3.50p+5.00p≤300

8.50p≤300

Now, you can solve for p:

p≤300/8.50

p≤35

According to this, the answer is that the inequality that could be used is 8.50p≤300 and the greatest number of people that can attend is 35.

The first three terms of a sequence are given. Round to the nearest thousandth (if
tangare [24]

The 7th term of the sequence to the nearest thousandth is 223.949

<h3>What are geometric sequences?</h3>

These are sequence that increases in an exponential form.

The formula for calculating the nth term of a geometric sequence is expressed as:

Tn = ar^n-1

Given the following parameters

a = 75

r = 1.2

n = 7

Substitute the given parameter into the formula

T7 = 75(1.2)^6
T7 = 223.949

Hence the 7th term of the sequence to the nearest thousandth is 223.949
