Answer:

The lowest score Stephen can get on the fifth test = 94 points    

Step-by-step explanation:

The marks scored by Stephen in test one = 88 points

The marks scored by Stephen in second test = 94 points

The marks scored by Stephen in test third = 89 points

The marks scored by Stephen in test fourth = 85 points

Let The marks scored by Stephen in test fifth be x points

Now, The average score in all the tests = 90 points

Sum of all the five tests = 88 + 94 + 89 + 85 + x

⇒ Sum of all five tests = 356 + x

Now, Average × 5 = Sum of five tests

⇒ 90 × 5 = 356 + x

⇒ 450 - 356 = x

⇒ x = 94

Therefore, The lowest score Stephen can get on the fifth test = 94 points

Set of integers x such that x - 5 ​
My name is Ann [436]

The set of integers that satisfy the inequality is x ∈ (-∞, 30) where x is an integer.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

The question is incomplete.

The complete question is:

Set of integers x such that x - 5 is less than 25​.

We have an inequality:

x - 5 < 25

Adding 5 both sides:

x - 5 + 5 < 25 + 5

x < 30

x ∈ (-∞, 30) where x is an integer.

Thus, the set of integers that satisfy the inequality is x ∈ (-∞, 30) where x is an integer.

In a football tournament, the Bees scored 9 less than three times as many points as the Hornets. The Wasps scored 28 more points
gladu [14]
B = bees, w = wasps, x = hornets

b + w + x = 184
b = 3x - 9
w = x + 28

(3x - 9) + (x + 28) + x = 184...combine like terms
5x + 19 = 184
5x = 184 - 19
5x = 165
x = 165/5
x = 33 <== points scored by Hornets
