42x=252
x=252/4
x=6
well hope that helps
Answer: Answer is the steps
Step-by-step explanation:
Step 1: Richie rewrite the equation as 24x + 18(x-2) =216
Step 2: Richie applied the distributive property to eliminate the parentheses and got the equation 24x + 18x - 32 = 216
Step 3: Richie combine like terms to get the equation 42x -36 =216
Step 4: Richie added 36 to both sides to get the new equation 42x = 252
Richie was not done solving for x so in
Step 5: Richie should have divided both sides by 42 to get the final answer
x = 6.
A luxury liner leaves a port on a bearing of 110 degrees and travels 8.8 miles. It then turns due west and travels 2.4 miles. How far is the liner from the port, and what is its bearing from the port?
Answer:
Distance= 6.6 miles
Bearing= N 62.854°W
Step-by-step explanation:
Let's determine angle b first
Angle b=20° (alternate angles)
Using cosine rule
Let the distance between the liner and the port be x
X² =8.8²+2.4²-2(8.8)(2.4)cos20
X²= 77.44 + 5.76-(39.69)
X²= 43.51
X= √43.51
X= 6.596
X= 6.6 miles
Let's determine the angles within the triangle using sine rule
2.4/sin b = 6.6/sin20
(2.4*sin20)/6.6= sin b
0.1244 = sin b
7.146= b°
Angle c= 180-20-7.146
Angle c= 152.854°
For the bearing
110+7.146= 117.146
180-117.146= 62.854°
Bearing= N 62.854°W
1. Explain the process for combining like terms for 12x - 3y + 8 - 5x + 4y
Answer: 7x+y+8
Step-by-step explanation:
Combining like terms is just like what it sounds. You take the like terms, or terms that have the same variables and such, and add them together.
For this problem, we can see that 12x and -5x are like terms because they both consist of a numerical coefficient and the variable x.
We can see that -3y and 4y are like terms because they both have a numerical coefficient and y for variable.
Now, we can combine like terms.
12x-3y+8-5x+4y [combine like terms]
7x+y+8
Is the product of fifteen negative integers positive or negative?
Answer:

I need some help on this
Answer:
When we are multiplying the same number, let it be n, m times, what we do is:
[tex]n^m[/tex], where n is the base and m the exponent.
In this case we have 4 fives, 2 threes, 3 x and 1 y which are being multiplied , so we can convert them to exponents:
4 fives: [tex]5^4[/tex]2 threes: [tex]3^2[/tex]3 x: [tex]x^3[/tex]1 y: yThen we multiply all: [tex]5^4*3^2*x^3y[/tex]

in the diagram?
<1and <3 measure

<2 and <4 measure
degrees.
(3x - 1)
1
3
2
(2x + 9)
Answer:
angle 1 and 3 are equal by vertically opp. angle
3x-1 = 2x +9
3x-2x = 9+1
x = 10
put the value of x in any equation
3(10)-1 = 29
angle 1 = angle 3 = 29
angle 2 + angle 3 = 180 ° (linear pair)
angle 2 = 180 -29
angle 2 = 149
angle = angle 3 = 149.

The 1-inch diameter pizza bite for $1 or the 10 inch diameter pizza for $10
Answer:
both same if we see. the one inch also costs l dollar wheras 10 dollar costs 10 inch. ok
Answer:
10in pizza
Step-by-step explanation:
We need to find the area of each pizza.
A = [tex]\pi[/tex][tex]r^{2}[/tex]
radius is 1/2 the diameter.
1in pizza 10in pizza
A = [tex]\pi[/tex]([tex].5^{2}[/tex]) A = [tex]\pi (2.5^{2} )[/tex]
A = .25[tex]\pi[/tex] A = 6.25[tex]\pi[/tex]
A = .79 A = 19.63
19.63/10 for [tex]in^{2}[/tex] per $1
So the 1in pizza bite is $1 for .79[tex]in^{2}[/tex] and we can see from the 10in pizza it's $1 for 1.96[tex]in^{2}[/tex]. So it is much better to get the 10in pizza.
Find all solutions by factoring.
4v2 - 25v = 21
Answer:
(4v + 3) and (v - 7)
Step-by-step explanation:
First rewrite 4v2 - 25v = 21 as 4v^2 - 25v - 21.
Let's now analyze -25v and -21. We need to identify two integers whose product is 21 and whose sum is -25.
Note that factors of -21 are ±1, ±3, ±7 and ±21. Factors of 4 (the coefficient of v^2) are ±1, ±2 and ±4.
Check out the following trial factors: (4v + 3) and (v - 7). Does this product come out to the given 4v^2 - 25v - 21? Yes. So the desired factors of 4v2 - 25v = 21 are (4v + 3) and (v - 7). Note how (3)(-7) = -21 and how 4(-7) + 3v add up to -25, the coefficient of the v term.

We can solve this problem in two ways.
1. From the description we conclude that the described sequence is a geometric sequence where the first term a₁ = 2 and common ratio r = 3, so:
[tex]\boxed{a_n=2\cdot3^{n-1}}[/tex]
Answer D.
2. The easiest way. We know that a₁ = 2, so let's substitute n = 1 for each of the possible answers:
A. 3·2ⁿ = 3·2¹ = 3·2 = 6 - Wrong
B. 2·3ⁿ = 2·3¹ = 2·3 = 6 - Wrong
C. 3·2ⁿ⁻¹ = 3·2¹⁻¹ = 3·2⁰ = 3·1 = 3 - Wrong
D. 2·3ⁿ⁻¹ = 2·3¹⁻¹ = 2·3⁰ = 2·1 = 2 - Correct.

Yes
No
Answer:yes
Step-by-step explanation:well its just yes so your welcomeWhich of these is least likey to describe a distance below sea level? Whole Number ,Integer, Rational Number, Real Number
Answer: A) Whole number
Explanation:
The set of whole numbers is {0,1,2,3,...} showing that negative values are not in this set. A distance below sea level is written as a negative (where positive values are above sea level). So you won't use the set of whole numbers for this type of problem.
In contrast, something like the set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ... } including negatives this time. For example, we can write -10 to indicate we're 10 feet below sea level. Rational numbers and real numbers can also be negative.

The golfer with the highest score in a tournament was nine over par. The golfer with the lowest was five below par. What was the range in golf scores?
Answer: The range in golf scores was 14.
Step-by-step explanation:
Range = Maximum - minimum
Values above some limit are represented by positive integers whereas values blow a certain limit is represented by negative numbers.
Given: The golfer with the highest score in a tournament was nine over par i.e. (9). The golfer with the lowest was five below par i.e. (-5 ).
So, the range in golf scores = 9-(-5)
= 9+5
= 14
Therefore, the range in golf scores was 14.

Answer: [-5,∞)
Step-by-step explanation:
z-18 ≥ -23 Add 18 to both sides
+18 +18
z ≥ -5
Which means x has to be greater than negative 5.
In interval notation it will be [-5,∞)
Answer:

E. 1
F. 3
G. 5
H. 6
please provide explanation
Answer:
y = 5
Step-by-step explanation:
We khow that x and y are consecutive integers and that x^2 is greater than y^2 since x^2-y^2=11
● so x is greater than y
● wich means that x = y+1
● x^2-y^2=11
● (y+1)^2-y^2 = 11
● y^2+2y+1-y^2=11
● 2y + 1 = 11
● 2y +1-1 = 11-1
● 2y = 10
●2y/2 = 10/2
● y = 5
