Answer 1

Answer:

Step-by-step explanation:

We want to solve the inequality:

[tex]\displaystyle 5.1(3 + 2.2x) > -14.25 - 6(1.7x+4)[/tex]

Distribute:

[tex](15.3+11.22x) > -14.25 + (-10.2x-24)[/tex]

Combine like terms:

[tex]15.3 + 11.22x > -10.2x-38.25[/tex]

We can add 10.2x to both sides:

[tex]15.3 + 21.42x > -38.25[/tex]

Subtract 15.3 from both sides:

[tex]21.42x > -53.55[/tex]

And divide both sides by 21.42. Hence:

[tex]\displaystyle x > -2.5[/tex]

This means all values greater than -2.5. Hence, in interval notation:

[tex](-2.5, \infty)[/tex]

In conclusion, our answer is C.

After a price increase of 20% the cost of entry to a museum rose to $25.80. Find the original
entry fee

Answers

Answer: 21.5

Explanation:

a x 120/100 = 25.8
a x 6/5 = 25.8
a = 25.8 x 5/6
a = 21.5

Where a is the original price.

Let call X the origninal price.

if it rose of 20 % , it's mean that it' be multiplicate by 1.20

so :

X*1,2 = 25.8

1.2X=25.8

Step-by-step explanation:

180-74=106

Answer: 106 degrees

============================================================

Explanation:

As the hint states at the top, supplementary angles add to 180 degrees

If we glued the angles together, then we'd form a straight line.

angleA+angleC = 180

74+C = 180

C = 180-74

When you write that M is a line, the sign for this would be a line with arrows on both of its end like this : <------------>

Now, due to the fact that lines look like this <------------>, we can cross out option C and D as they both aren't lines but points. Points go like this: ---->

Option B says, "line EB", this can't be true because E corresponds with the letter F, it can't become a line with B hence why the only option true here is choice A.

This is the flip side of the previous one I answered. The range is the set of all y-values or outputs. Since you can only spend increments of $1.25, you cannot have all the numbers from 12 to 0 in your range.

The range is 12 dollars minus all possible increments of 1.25, until you can’t buy any more candy.

12
12-1.25 = 10.75
10.75-1.25 = 9.50

The Answer is:

p=15

5x3=15

So that must mean 15/5=3

Hi! I'm happy to help!

To make this equation easier, we can use the inverse operation, multiplication (instead of division).

p÷5=3

3×5=p

Doing this will give you the same answer, it just makes it easier. 3 times 5 is 15, so p=15

We can double check our answer by putting in 15 for p.

p÷5=3

15÷5=3, this is true, so our answer is correct.

IQR:5.5

How does adding 5 to each of the values in the data set impact the measures of variability?

Answers

Answer:

see below:

Step-by-step explanation:

the median will become a larger, different number. The mean will also become a larger number, since it will still be dividing by the same amount of numbers in the equation, only the quantity will become larger. Same with standard deviation. The IQR will change, because the amount of the two numbers you'll be subtracting will end up greater than before.

Concept:

Here, we need to understand the idea of evaluation.

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

Given expression

f(n) = 3n + 5
