Answer:
46x + 23 = 46x +23
Step-by-step explanation:
46x - 23 = 46x + 23
Subtract 46x from each side
-23 = 23
This is not true so there are no solutions
-46x + 23 = 46x + 23
Add 46x to each side
23 = 96x +23
Subtract 23 from each side
0 = 96x
x=0 one solution
46x + 23 = 46x +23
Subtract 46x from each side
23 = 23
This is always true so there are infinite solutions
-46x - 23 = 46x + 23
add 46x to each side
-23 = 96x +23
subtract 23 from each side
-46 = 96x
x = -1/2
Solve x + x + 2 + 2x = -2.

Answer:
[tex]x=-1[/tex]
Step-by-step explanation:
[tex]x + x + 2 + 2x = -2[/tex]
First, we need to collect like terms:
[tex]4x+2=-2\\4x=-4[/tex]
Then we divide both sides by 4:
[tex]\frac{4x}{4}=\frac{-4}{4}\\x=-1[/tex]
The answer is x = -1.
To solve this equation, you must collect like-terms by adding together x terms and numbers, and then rearrange to get x on one side and numbers on the other:
x + x + 2 + 2x = -2
4x + 2 = -2
- 2
4x = -4
÷ 4
x = -1

Question:
The quantities x and y are proportional.
x y
5.8 7.5
11.2
Find the constant of proportionality (r) in the equation y=rx
Answer:
The constant of proportionality is 75/58 or 1.29
Step-by-step explanation:
Given
The table above
Required
Find the constant of proportionality
The question has an incomplete table but it can still be solved because x and y are proportional.
Given that
y = rx
Make r the subject of formula
Divide through by x
y/x = rx
y/x = r
r = y/x
When y = 7.5, x = 5.8
Substitute these values
r = y/x becomes
r = 7.5/5.8
Multiply denominator and numerator by 10
r = (7.5 * 10)/(5.8 * 10)
r = 75/58
In this case, it's best to leave the answer in fraction.
However, it can be solved further.
r = 75/58
r = 1.29 (Approximated)
Hence, the constant of proportionality is 75/58 or 1.29
Answer:
the correct answer is 1

The equivalent expression in the simplified form of the expression [4a²(b⁻²)] / [16(a⁻³)b] will be [4 · a² · a³] / [16 · b² · b].
What is an equivalent expression?The equivalent is the expression that is in different forms but is equal to the same value.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The expression is given below.
⇒ [4a²(b⁻²)] / [16(a⁻³)b]
Simplify the expression, then we have
⇒ [4a²(b⁻²)] / [16(a⁻³)b]
⇒ [4 · a² · a³] / [16 · b² · b]
The equivalent expression in the simplified form of the expression [4a²(b⁻²)] / [16(a⁻³)b] will be [4 · a² · a³] / [16 · b² · b].

Starting at time t = 0, the altitude of one helicopter is given by A1 = 600 + 150t, and the altitude of a second helicopter is given by A2 = 1250 + 50t. Which equation represents the difference of their altitudes A at time t?
Answer:
The equation for difference in altitude of the two helicopters is A = 650 - 100t
Step-by-step explanation:
Given;
The altitude of one helicopter is, A1 = 600 + 150t
The altitude of a second helicopter is, A2 = 1250 + 50t
Their difference in altitude, A at time t, is calculated as
A₂ - A₁ = A = (1250 + 50t) - (600 + 150t)
A₂ - A₁ = A = 1250 + 50t - 600 -150t
A₂ - A₁ = A = 1250 - 600 + 50t - 150t
A₂ - A₁ = A = 650 - 100t
Therefore, the equation for difference in altitude of the two helicopters is A = 650 - 100t

Raj's company ships T-shirts in boxes shaped like cubes. The picture below shows the cube
and its net. Raj is designing labels for all of the faces of the boxes. What is the surface area
of each box that Raj needs to cover with labels?
Answer: The surface area of each cube is 24 ft² (24 square feet)
Step-by-step explanation: The boxes according to the question are shaped like cubes, which means the shape we have here has square faces on all sides. Also the boxes have been opened up into nets and this shows each box as having 6 faces.
The area of each face is derived as follows;
Area = L x W
Area = 2 x 2
Area = 4 ft²
Having calculated the surface area of each face, a box or cube with 6 faces will have its surface area as;
Area of box = Face area x 6
Area of box = 4 x 6
Area of box = 24 ft²
Therefore in designing labels for all of the boxes, Raj would need 24 square feet of label for each box.
The surface area of the box is 24 square ft if the side length is 2 ft after using the surface area formula.
What is a cuboid?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape.
We have a box, the side length of the box is 2 ft.
The surface area of the box = 6a²
a is the side length.
a = 2 ft
Surface area of the box = 6(2)² = 24 square ft
Thus, the surface area of the box is 24 square ft if the side length is 2 ft after using the surface area formula.

Which value of x makes this sentence true?
1/2 + x=10/11
A:9/22
B:11/13
C:8/9
D:13/22
Answer:
9/22
Step-by-step explanation:
1/2 + x=10/11
Subtract 1/2 from each side
1/2-1/2 + x=10/11-1/2
x = 10/11 -1/2
Getting a common denominator of 22
x = 10/11*2/2 -1/2 *11/11
x = 20/22 - 11/22
x = 9/22
Answer:
x=9/22
Step-by-step explanation:
u have to subtract 1/2 on both sides, so u can get X by itself
1/2-1/2+x=10/11-1/2
get the common denominator for 10/11 and 1/2
10/11 times 2/2=20/22
1/2 times 11/11=11/22
20/22-11/22= 9/22
x=9/22
ANSWER CHECK
substitute the variable X for 1/22
1/2+9/22=10/11
common denominator
1/2 times 11/11=11/22
11/22+9/22= 20/22 or 10/11

Predict how many times you will roll a number less than 5 if you roll a standard number cube 350 times. Round to the nearest integer, if necessary.
Answer:
233 Times
Step-by-step explanation:
In a standard cube, there are 6 faces labelled 1 to 6.
Numbers less than 5=1,2,3,4
The probability of rolling a number less than 5 =4/6
Therefore, if the standard number cube is rolled 350 times.
Number of Expected Outcome Less than 5
[tex]=\dfrac{4}{6}X350[/tex]
[tex]=233.33\\\approx 233$ (to the nearest integer)[/tex]
We would roll a number less than 5 233 times.
