2 2/3 x64 come on i give you lot of points
Answer:
170 2/3
Step-by-step explanation:
2 2/3 x 64 is the same thing as:
[tex]\frac{8}{3}[/tex] × [tex]\frac{64}{1}[/tex] = ?
Multiply across.
8 x 64 = 512
3 x 1 = 3
Simplify the fraction.

Considering the points on the unit circle, it is found that the angle is on the second quadrant, hence the possible angles are between 90º and 180º.
What is the unit circle?For an angle [tex]\theta[/tex] the unit circle is a circle with radius 1 containing the following set of points: [tex](\cos{\theta}, \sin{\theta})[/tex].
In this problem, we have a negative cosine and a positive sine, hence it is an angle on the second quadrant, which can be values between 90º and 180º.

What will be the total cost of Maria's ARM if the term of the loan were 25 or 20 years instead of 30? Use the variable rate loan calculator to find the answers. Write them in the spaces below.
Mortgage Term | Total Cost
25 years: |
20 years: |
Answer:
The total cost of the loan goes down as the term decreases. Although the amount of the loan itself remains the same, the total amount of interest Maria would have to pay in interest decreased when the term of the loan decreased. However, the monthly payments increased when the term decreased. So, a shorter term saves interest but requires greater monthly payments.

Solve the system of equations using subtraction.
2x−4y=−4
2x+ y =11
Answer:
(4, 3 )
Step-by-step explanation:
2x - 4y = - 4 → (1)
2x + y = 11 → (2)
subtract (2) from (1) term by term to eliminate x
(2x - 2x) + (- 4y - y) = - 4 - 11
0 - 5y = - 15
- 5y = - 15 ( divide both sides by - 5 )
y = 3
substitute y = 3 into either of the 2 equations and solve for x
substituting into (2)
2x + 3 = 11 ( subtract 3 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
solution is (4, 3 )
x+8=6 solve each equation
Answer:
=> x = -2Step-by-step explanation:
=> x+8=6
=> x = 6-8
=> x = -2
Answer:
-2
Step-by-step explanation:
x= negative 2
-2 + 1= -1
-2 + 2=0
-2 + 3=1
-2 + 4=2
-2+ 5=3
-2 +6=4
-2 + 7=5
-2 +8=6 so this problem is x + 8 and the x= - 2 so your answer is -2 + 8=6

what is the coefficient in the expression below 2x-8
Answer:
2x - 8
Parts of an equation:
2 - coefficient
x - variable
8 - constant
The number 2 is not a coefficient in the expression. FALSE.
The expression has three terms. FALSE. two terms only: 2x & 8
The variable in the expression is x. TRUE
The number 2 is a constant in the expression. FALSE
The expression has one variable term. FALSE. 2x is term but it's a combination of a number and a letter. Variable term is letter only.
Hello.
The coefficient is the number before a variable (letter)
The constant is also a number.
What's the difference between a constant and a coefficient?
Well, a coefficient is always before a variable, and a constant is just a number (without any variables next to it)
In this case, the variable is x, the number before x is 2, and 8 is the constant.
Therefore, 2 is the coefficient in this expression.
I hope it helps.
Have a nice day.

What is the value of x in the figure below?
Answer:
9
Step-by-step explanation:
3x+8 = 35
3x = 27
x = 9
Hope this helps :)
Step-by-step explanation:
Here, (3x + 8)° and 35° are vertically opposite angles which are equal, therefore,
3x + 8 = 35
3x = 35 - 8
3x = 27
x = 27/3
x = 9

Answer:
Given,
Area of the Square = ( x² - 10x + 25 ) m²
We have to find: Length of the side of the square.
Let s be the side of square.
We find length of side of the by using factorization.
According to the question,
s² = x² - 10x + 25
s² = x² - 5x - 5x + 25
s² = x( x - 5 ) - 5( x - 5 )
s² = ( x - 5 )( x - 5 )
s² = ( x - 5 )²
Taking square root on both sides we get,
s = x - 5
Therefore, Expression that represents the length of one side of the square is x - 5.

(6r-7)
55°
Answer:
r=7
Step-by-step explanation:
6r-7+90+55=180
6r+138=180 ----- 6r=180-138
6r=42 ----- divide both sides by 6
r=7
(We get the 90 from the 90degrees in the middle of this supplementary angle and the total, 180, from the straight angle made from all three angles.)

Answer: the question wasn't clear hence just defined the meaning to it
Step-by-step explanation:
A linear inequality resembles in form an equation, but with the equal sign replaced by an inequality symbol. The solution of a linear inequality is generally a range of values, rather than one specific value. Such inequalities arise naturally in problems involving words such as 'at least' or 'at most'.

Answer:
width = 9/2 inches, length = 18 inches
Step-by-step explanation:
Step-by-step explanation:
l = length
w = width
l×w = 81 in²
l = 2w + 9
we can use the identity of the second equation in the first equation :
(2w + 9)×w = 81
2w² + 9w = 81
2w² + 9w - 81 = 0
the general solution to such a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = w
a = 2
b = 9
c = -81
w = (-9 ± sqrt(9² - 4×2×-81))/(2×2) =
= (-9 ± sqrt(81 + 648))/4 =
= (-9 ± sqrt(729))/4 = (-9 ± 27)/4
w1 = (-9 + 27)/4 = 18/4 = 9/2 in
w2 = (-9 - 27)/4 = -36/4 = -9
a negative solution for a side length does not make any sense, so, width = 9/2 in is the only valid solution.
l = 2w + 9 = 2×9/2 + 9 = 9+9 = 18 in
so, the last answer option is correct.
