What is the solution to the inequality 7<=-3x-4

kipiarov [429]

Answer:

The nearest option is -3 (negative 3)

So, Option B is correct.

Step-by-step explanation:

We need to solve the inequality $7 \leq -3x-4$

Solving:

Step 1: Switching sides of inequality and reversing the inequality

$-3x-4\geq 7$

Step 2: Adding 4 on both sides

$-3x-4+4\geq 7+4\\-3x\geq 11$

Step 3: Dividing both sides by -3 and reversing the inequality

$\frac{-3x}{-3}\leq \frac{11}{-3} \\x\leq -3.6\\$

The nearest option is -3 (negative 3)

So, Option B is correct.

on the football team, two out of every seven players are seniors. if the team has 84 players, how many are not seniors.

zaharov [31]

There are 60 players on football team that are not seniors.

Step-by-step explanation:

<u>Method 1:</u>

Given

Total students = 84

Also given that

2 out of 7 are seniors

Which is 2/7

So in order to find the total number of seniors we will multiply the whole number of students to 2/7

$Senior\ students = \frac{2}{7} * 84\\= 24$

So there are 24 seniors on the football team.

Players that are not seniors = 84 - 24 = 60

There are 60 players who are not seniors.

<u>Method 2:</u>

We can divide the total number by 7, to get how many sets of 7 players will be there

= 84/7 = 12

Now,

Multiplying 12 with 2 will give us the number of seniors in football team.

12*2 = 24 seniors

So,

Not seniors =84-24 = 60
