-8 (4 - 4a) -2 = 222
Answer:
a = 8
Step-by-step explanation:
-32 + 32a -2 = 222
-34 + 32a = 222
32a = 256
a = 8
Answer:
[tex]a = 8[/tex]
Step-by-step explanation:
Step 1: Distribute
[tex](-8 * 4) + (-8 * -4a) - 2 = 22[/tex]
[tex]-32 + 32a - 2 = 222[/tex]
Step 2: Combine
[tex](-32 - 2) + 32a = 222[/tex]
[tex]-34 + 32a = 222[/tex]
Step 3: Add 34 to both sides
[tex]-34 + 32a + 34 = 222 + 34[/tex]
[tex]32a = 256[/tex]
Step 4: Divide both sides by 32
[tex]32a / 32 = 256 / 32[/tex]
[tex]a = 8[/tex]
Answer: [tex]a = 8[/tex]
Simplify the expression. (x1/2y1/3)(x1/4y1/6) A) x1/2y1/2 B) x1/8y1/18 C) x2y2 D) x3/4y1/2
Answer:
[tex](D)x^{3/4}y^{1/2}[/tex]
Step-by-step explanation:
We are required to simplify the expression: [tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})[/tex]
This is a product and the first thing we will do is to collect like terms:
[tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})=x^{1/2}x^{1/4}y^{1/3}y^{1/6}[/tex]
Next, we apply the addition law of indices: [tex]x^a X x^b =x^{a+b}[/tex]
[tex]x^{1/2}x^{1/4}y^{1/3}y^{1/6}=x^{1/2+1/4}y^{1/3+1/6}\\\\=x^{3/4}y^{1/2}[/tex]
Therefore, [tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})=x^{3/4}y^{1/2}[/tex]

a. How much money do you have left if you ride each ride once?
You have $
left.
b. Do you have enough money to ride each ride twice? Explain.
It costs $
to ride each ride once, and you have $
left.
Question 2
response - correct
To find out how much money you have left after riding each ride once, subtract the total cost of all the rides from the amount of money you have. To find out if you have enough money to ride each ride twice, multiply the cost of each ride by 2 and check if it is less than or equal to the amount of money you have.
Explanation:a. To determine how much money you have left if you ride each ride once, you need to know the cost of each ride. Let's say each ride costs $3. To find out how much money you have left, you subtract the total cost of all the rides ($3 x number of rides) from the amount of money you have. So, in this case, you have $15 - ($3 x number of rides) left.
b. To determine if you have enough money to ride each ride twice, you multiply the cost of each ride by 2 and check if it is less than or equal to the amount of money you have. So, if each ride costs $3, you would calculate $3 x 2 = $6 to see if it is less than or equal to $15.

What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The block has the following dimensions:
( L x w x h ) = ( 8 x 5 x 6 ) in
We will determine the surface area of each unique face of the block given in the attachment.
Surface area of the face ( 8 x 5 ):
Area = ( 8 )×( 5 )
Area = 40 in²
Surface area of the face ( 8 x 6 ):
Area = ( 8 )×( 6 )
Area = 48 in²
Surface area of the face ( 6 x 5 ):
Area = ( 5 )×( 6 )
Area = 30 in²
Hence, Create a stack where the 6-inch-by-8-inch faces of the blocks touch is the correct strategy for stacking the blocks

A scientist calculated the mean and standard deviation of a data set to be Mu = 120 and Sigma = 9. She then found that she was missing one data value from the set. She knows that the missing data value was exactly 3 standard deviations away from the mean. What was the missing data value?
Answer:
The missing data value is 147
Step-by-step explanation:
The mean is 120
The standard deviation is 9
Missing data value = ?
From the question, the missing data value is 3 standard deviation away from the mean.
3 standard deviation = 3 * 9 = 27
3 standard deviation from the mean = 120 + 27 = 147
The missing data value is what we get after adding 3 standard deviation from the mean.
Away here means ahead which is sum.

38.5 centimeters squared
44.0 centimeters squared
150.0 centimeters squared
153.9 centimeters squared
The area of a circle is πr². We know r is 7, so the area is π * 7² = 49π.
Substituting, we have 49 * 3.14 = 153.86, which rounds to 153.9 centimeters squared.
The area of circle with a radius of 7 cm is,
⇒ 153.9 centimeters squared
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We have to given that;
Radius of circle = 7 cm
Now, We know that;
Area of circle is,
A = πr²
Where, 'r' is radius of circle.
Here, Radius of circle = 7 cm
Hence, The area of circle with a radius of 7 cm is,
⇒ A = πr²
⇒ A = 3.14 × 7²
⇒ A = 3.14 × 49
⇒ A = 153.9 centimeters squared
Thus, The area of circle with a radius of 7 cm is,
⇒ 153.9 centimeters squared

Explain hard to tell whether (2,-1) is a solution of the equation Y= 3X -2 without using the graph
Answer:
Considering the equation given:
[tex]y= 3x -2[/tex]
As a function:
[tex]f(x)= 3x -2[/tex]
[tex]$(2, -1)$[/tex] states for [tex](x, y)[/tex], which means, [tex]x=2[/tex] and [tex]y=-1[/tex]
[tex]f(2)= 3(2) -2\\f(2)= 6-2\\f(2)= 4[/tex]
[tex]4\neq -1[/tex]
Therefore, [tex]$(2, -1)$[/tex] is not a solution for the equation given and for the function.
Final answer:
To determine if (2,-1) is a solution of Y = 3X - 2, we substitute x=2 into the equation and simplify. The resulting y-value does not match the y-coordinate of the point, therefore (2,-1) is not a solution.
Explanation:
To verify whether the point (2,-1) is a solution to the equation Y = 3X - 2, we need to substitute the x-value of the point (2) into the equation and see if the resulting y-value equals the y-value of the point (-1). If they match, then the point is a solution of the equation.
Let's go through the step-by-step process:
Substitute the x-coordinate of the point into the equation: Y = 3(2) - 2.Simplify the right side of the equation: Y = 6 - 2 which equals 4.Compare this value to the y-coordinate of the point, which is -1.Since the calculated y-value (4) does not equal the y-coordinate of the point (-1), the point (2,-1) is not a solution of the equation Y = 3X - 2.

Answer:
No he is not correct.

(x - 2)(x - 2 + x + 4) = 4(4 + 5)
(x - 2)(2x + 2) = 4(9) = 36 ← distribute and simplify the left side
2x² + 2x - 4x - 4 = 36
2x² - 2x - 4 = 36 ( subtract 36 from both sides )
2x² - 2x - 40 = 0 ( divide through by 2 )
x² - x - 20 = 0 ← in standard form
(x - 5)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4
