Answer:
x = -7
Step-by-step explanation:
-5( x + 3 ) = 20
Distributive property ( multiply whatever is in the parenthesis by -5)
-5 * x + -5 * 3 = 20
-5x - 15 = 20
Add 15 on both sides
-5x - 15 + 15 = 20 + 15
-5x = 35
Divide by -5 on both sides to isolate the variable
-5x/-5 = 35/-5
x = -7
Check...
Substitute the "x" with -7 since we already got that as our solution
-5( x + 3 ) = 20
-5( -7 + 3 ) = 20
Distributive property
-5 * -7 + -5 * 3 = 20
35 - 15 = 20
20 = 20 CORRECT

The first rule is multiply by 2, then subtract 4 starting from 6. The second rule is add 3, then multiply by 2 starting from 1. What are the first four ordered pairs using the two sequences?
(0, 0) (6, 1), (8, 2), (12, 22)
(6, 1), (10, 8), (14,22), (22, 50)
(6, 1), (8, 8), (12, 20), (20, 45)
(6, 1), (8, 8), (12, 22), (20, 50)
Answer:
(6,1), (8,8), (12,22), (20,50)
Step-by-step explanation:
The required sequence of ordered pairs is (6, 1), (8, 8), (12, 22), (20, 50). Option D is correct.
The first rule is to multiply by 2, then subtract 4 starting from 6. The second rule is to add 3, then multiply by 2 starting from 1. What are the first four ordered pairs using the two sequences to be determined?
In mathematics, it deals with numbers of operations according to the statements.
Let the number be x for the first sequence and y for the second sequence.
The first rule is to multiply by 2, then subtract 4 starting from 6.
= 2x - 4
the sequence can be given as
6 is the first number
next number = 2(6) - 4
= 12-4
= 8
So the next term is 8. Similarly next 2 terms can be given as 12 and 20
Values of x = 6, 8, 12, 20
Now, the second rule is to add 3, then multiply by 2 starting from 1.
= (y + 3)2
First term = 1
Next term = (1 + 3)2
= 8
Similarly, the next two terms can be obtained.
y = 1, 8, 22, 50
Thus, the ordered pair can be formed as (6, 1), (8, 8), (12, 22), (20, 50).

1) width = 10 + 2x
length = 20 + 2x
2) area = (10 + 2x)(20 + 2x)

3) 4(5 + x)(10 + x) = 600
(5 + x)(10 + x) = 150
50 + 15x + x^2 = 150
x^2 + 15x - 100 = 0

Find the 24th term.
-9, 0, 9, 18, 27, ...
24th term = [? ]
Answer:
198
Step-by-step explanation:
Answer: 198
Step-by-step explanation:
Firstly, you must find the nth term.
the sequence is: -9, 0, 9, 18, 27, ...
find the difference between each term. in this sequence, the difference is 9, so it is 9n
then you must find the difference between the sequence 9n and this sequence. 9n is:
9, 18, 27, 36, 45, ...
now find the difference between 9n and our sequence.
adjustment = -18
so the nth term is 9n - 18
now you need to substitute 24, as that is the term you would like to find out, in place of n.
so, our n term looks like this: 9(24)-18
9 x 24 = 216
216 - 18 = 198
hence, the answer is 198.
hope this helps.

The diameter of a hat is 6.8 inches. What is the distance around the hat using π = 3.14? Round to the hundredths place.
2.17 inches
10.68 inches
21.35 inches
36.29 inches
The required distance around the hat is approximately 21.35 inches. Option C is correct.
What is the circumference of the circle?To find the circumference of a circle, we use the formula C = πd, where C is the circumference, π is the mathematical constant pi (approximately equal to 3.14), and d is the diameter of the circle.
Here,
The distance around a circle is given by the formula circumference = π × diameter.
Substituting the given values, we get:
circumference = 3.14 × 6.8
circumference = 21.352
Rounding to the nearest hundredth, we get:
circumference ≈ 21.35 inches
Therefore, the distance around the hat is approximately 21.35 inches.

You are given a triangle with side lengths of 6, 9, and 12. Is the triangle a right triangle? How do you know?
Answer:
No, it's not
Step-by-step explanation:
You choose the longest side which is 12 and apply the theory of phitagors
The longest side which is the hypotenuse in a right triangle = square root the square sum for each side
So to be a right triangle it should be
\( \sqrt{ {9}^{2} + {6}^{2} } = 10.8 \: \: that \: doesnt \: equal \: 12\)
So it's not a right triangle.
Look at the famous right triangle whose side are 5(hypotenuse), 4, 3
\( \sqrt{ {4}^{2} + {3}^{2} } = 5\)
So it's a right triangle

Distribute the 7, then solve for x.
7x - 35 = x + 13
6x = 48 (Added 35, subtracted x)
x = 8 (Divided by 6)
One solution
-6x=-5(x-1)-x
Distribute the -5, then combine like terms. Solve for x.
-6x = -5x + 1 - x (negative times negative equals positive)
-1 = 0 (Added 6x, subtracted the x from 1x, subtracted 1)
No solution
-4(x-2)=-2(x-17/2)
Distribute the -4 and -2, then solve for x.
-4x + 8 = -2x + 17 (negative times negative equals positive) (the 2's cancel out to be 17)
-9 = 2x (Added 4x, subtracted 17)
-9/2 = x
One solution
3 - 4x + 5 = 2(8 - 2x)
Distribute the 2, combine like terms. Solve for x.
8 - 4x = 16 - 4x

In the diagram of a fan below, CA = 9.5 in. this is the distance from the center to a point on the fans blade. what is the distance point A travels in one rotation of the fans blade
Answer:
About 59.66 inch
Step-by-step explanation:
To find the circumference you first have to find the diameter which is the double the radius. Since 9.5 is the radius of this circle, the diameter is, 9.5x2=19.
With the diameter of 19, you multiply the 19 with pie which is approximately 3.14. The answer is 19x3.14=59.66
