Answer:

The answer is

[tex] - 5 < x < 2[/tex]

Step-by-step explanation:

First you have to seperate them :

[tex] - 2 < x + 3[/tex]

[tex]x + 3 < 5[/tex]

Next you can solve it by moving all the unrelated terms to the other side :

[tex] - 2 < x + 3 \\ - 2 - 3 < x + 3 - 3 \\ - 5 < x \\ x > - 5[/tex]

[tex]x + 3 < 5 \\ x + 3 - 3 < 5 - 3 \\ x < 2[/tex]

Answer:

-5 < x < 2

Step-by-step explanation:

Subtract 3 from each of the three sides.

-2 < x + 3 < 5

-2 - 3 < x + 3 - 3 < 5 - 3

-5 < x < 2

Answer:

C. Acute and Isosceles

Step-by-step explanation:

Acute means the angles are less than 90 degrees. All of the triangles angles are less than 90 degrees.

Isosceles means they have 2 sides of equal length. In the triangle, there are 2 sides with the length of 6 in, making this an isosceles triangle

Answer:

D. $66.42

Step-by-step explanation:

If I'm correct (which I highly doubt...)

You multiply 7.38 and 9

That should give $66.42

Sorry if I'm wrong...

And if I'm wrong, my second option would be C. $0.82

Answer:

7 children tickets

Step-by-step explanation:

Answer: The MAD is 1.6

Step-by-step explanation:To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.

Answer:

1. No, Joe is not correct

2. [tex]\angle 5=72^{\circ}[/tex]

Step-by-step explanation:

Given: b and c are parallel lines

To find:

1. whether the given statement is correct or not

2. [tex]\angle 5[/tex]

Solution:

1.

Sum of two angles that form a linear pair is equal to [tex]180^{\circ}[/tex]

[tex]\angle 3+72^{\circ}=180^{\circ}[/tex] (linear pair)

[tex]\angle 3=180^{\circ}-72^{\circ}=108^{\circ}\neq 90^{\circ}[/tex]

So, Joe is not correct

2.

If two lines are parallel then alternate interior angles are equal.

As b and c are parallel lines,

[tex]\angle 5=72^{\circ}[/tex] (alternate interior angles)

Answer: 36%; yes, the % change is equal to the percent discount

Step-by-step explanation:

Initial price = $69.99

Final price = $44.99

change in price = |(final - initial)|

change in price = |(44.99 - 69.99)|

change in price = $25

25/69.99 = x/100

100(25/69.99) = x

100(0.357) = x

35.7% = x

x = 36%

Answer:

B. F(11) = 32

Step-by-step explanation:

From the explicit equation,

F(n) = 2 + 3(n - 1)

F(11) = 2 + 3(11 - 1)

F(11) = 2 + 33 - 3

F(11) = 35 - 3

F(11) = 32

The 11th term of the sequence with an explicit rule is 32

Hello! The answer is 20.66

Step-by-step explanation:

1. You have to add up all the numbers in the set (248)

25) x = 18 26) x = 50

Step-by-step explanation:

25) 108 + 4x = 180

108 + 4x = 180

-108           -108

4x = 72

x = 18

26)

101 + (x + 29) = 180

101 + 29 + x = 180

130 + x = 180

-130        -130

x = 50

Answer: C.

f(t) = P(1.02)4t

Step-by-step explanation:

f(t) = P(1.02)4t will have the greatest compound interest because the interest is on quarterly bases with an increment of 1.02 and the rate of 8%

Note : 8/100 × 1/4 = 0.02

There is no increment in D and A is yearly based. Option C is for 6 month.

Answer:

30t−4

Step-by-step explanation:

Answer: z=2.8

This is how I do!

Step-by-step explanation:

51-2z-8z=23

We simplify the equation to the form, which is simple to understand  

51-2z-8z=23

We move all terms containing z to the left and all other terms to the right.  

-2z-8z=+23-51

We simplify left and right side of the equation.  

-10z=-28

We divide both sides of the equation by -10 to get z.  

z=2.8

Answer:

Z=2.8

Step-by-step explanation:

51-10z=28

Step-by-step explanation:

i took the test and got it right so... and do you have Mr. Hoffman

The sum of the first six terms of the following sequence is ∑(from i=1 to 6) (-10 - 3(i-1)), the correct option is A.

Lets suppose its initial term is f=a , multiplication factor is  r

and let it has total n terms, then, its sum of a geometric sequence is given as:

[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]

(sum till nth term)

We are given that;

The sequence;  −10, −13, −16, …

Now,

The given sequence is an arithmetic sequence with first term (a1) = -10 and common difference (d) = -3.

Using this formula, we can find the first six terms of the sequence as follows:

a1 = -10

a2 = -10 + (-3) = -13

a3 = -10 + 2(-3) = -16

a4 = -10 + 3(-3) = -19

a5 = -10 + 4(-3) = -22

a6 = -10 + 5(-3) = -25

We can represent the sum of the first six terms using sigma notation as:

∑(from i=1 to 6) ai = (-10) + (-13) + (-16) + (-19) + (-22) + (-25) = -105

The sum of the first six terms of the given sequence is -105.

Using sigma notation, we can write this as:

∑(from i=1 to 6) (-10 - 3(i-1)) = -105

Therefore, by the geometric sequence the answer will be ∑(from i=1 to 6) (-10 - 3(i-1)).
